I would like to say BIG THANKS to Stanislaw SP6MLK for great hospitality and well organize seminar. I was so happy to see after very long time our well known EME guru Erick OE9 ERC and many other friends. Anyway, as I inform you last week here, I was testing setup which will be use in EME expedition to Morocco in October this year. I had built 6cm system, which is finalized and is in final version now. I was so happy to see, that all works well. Great thanks is going to Hannes OE5JFL and Walter ON4BCB for all upgrades of controlling system. To Eddy ON7UN for help with very nice 180cm dish and many others for consultations and discussing. Whole Sun orbit we were able to see shadow on right place in the dish and noise measured was constant all the time. Measured results are: Sun noise 9,8dB - 10dB - exactly according VK3UM calculator Ground noise/Cold Sky noise 5,4dB Own echo visible on spectrum waterfall, but -4dB and very week hearable. Also expected according VK3UM calculation. Last big thanks go to OK1KIR team and Dan HB9Q, which even so worse Moon conditions were on the Moon for test. I was so happy work them as SP6MLK with very good signals and according their report, they did not have any problem to copy me. We worked CW, SSB, and JT4 with HB9Q and CW and JT with OK1KIR. Pity that Jac PA3DZL had so bad WX in that time. Now I am finishing last details in 3cm band TRV upgrade and hope to test it soon. I am happy announce that Yoshiro JA4BLC send me convertor from 220MHz to 144 MHz and I will be able test also JA stations on 10450 MHz.

I used an SM6FHZ feed with linear polarisation to my 2.3m prime focus dish. There was a noticeable improvement over the re-purposed commeercial Chaparral feed I had been using. I was able to quickly change over the feeds to do an A/B comparison. The sun noise/cold sky was improved to 12.2dB from 10.8dB and moon noise from 0.7 to 1.0dB. Ground noise/cold sky on the 'FHZ was 5.2dB I need to improve tracking still further and find a way to incorporate the SSPA. I was so busy making measurements that I didn't really bother to check who the stations were that kept popping up, except HB9Q and OZ1LPR! I felt this was a successful improvement and I feel encouraged. I hope to be fully operational later this year. 73 de Sam, G4DDK From dfaessler at bluewin.ch Mon Jun 26 14:18:22 2017 From: dfaessler at bluewin.ch (=?utf-8?Q?Dominique_F=C3=A4ssler?=) Date: Mon, 26 Jun 2017 14:18:22 +0200 Subject: [Moon] FW: [Moon-Net] Test Message-ID: <004401d2ee76$4df3a350$e9dae9f0$@ch> Peter, Vlada the fact that using a 2.4m dish LIN Pol can truly random copy CP signal from 1m dish with only 50W at PA output (net at feed maybe 40W) is a very strong argument to change to CP for everybody, as decided at the Prague EME conference long ago. Given, the LIN Pol stn would have had CP instead, the signal would have been much easier copied, all losses by the not perfect CP feed included. The advantage would have been approx. 2.5dB. I made 2 fully random QSOs CP with 1m dish and moderate power. Already 1.2m dish would improve another 3dB. Btw: I like "insane" power by others, it enables me to copy them even with small dish and WP "wrong Pol") I think time has come to go CP.

I have also given the CP/LIN some thoughts and I get by using V pol and twist in case of need. Problem is no one get their CP Feeds near the performance of Lin feeds. There are additional losses in the CP feeds. Furthermore when one design a feed it is almost not fitting 100% illumination wise. Specially in Offset dishes that can be felt. Also dimensions are quite critical on 3cm making a good Circular Feed. I would need a waveguide Feed for Andrew/channelmaster dish. I am sure it will be hard to get all to agree on the topic. Agreed power is insane at JLW and at my Station. Well my TWTA is a Class A TWT and does like making max power out in the feed. Otherwise it is just dissipated in the TWT. It draws 3000W from the 230V when PTT. It delives around 750W on the flange but big loss in feeder system. Why alligator power ???. Well it makes everybody able to hear a signal from the moon same as the Beacon but only better as there Is actually a person behind. I try to infect as many as possible to this challenging part of our hobby. Hearing a signal from the moon makes them want more. Even my own kids are very amazed when I let them say a few words and hear them back from the Moon :o). Vlada it is stations like you that makes the band a success as it is always possible to work you. By the way soon I be QROO on 5.7Ghz also I just got the Waveguide feeder so will make 500W where around 300W will hit my Feed horn that actually is CP :O) Have a nice day both of you. 73 Peter LPR From: moon-net-bounces at mailman.pe1itr.com [mailto:moon-net-bounces at mailman.pe1itr.com] On Behalf Of vlada Sent: 26. juni 2017 12:26 To: Dominique Faessler Cc: Moon-net Subject: Re: [Moon-Net] [Moon] Test Hi Dominique, first sincere congrats to 1st CW 3cm QSO. However something still to think about as the both OZ1LPR and SP6JLW have huge TX power. Have you ever found ours 50W signal during the contest ? FYI, we made 32 CW QSOs. E.g. we made also random CW QSO with OK2AQ with 1.2m dish and similar power (close to 50W at max) at spread of 120Hz, but with linear polarisation ! Seems, these 3dB is terrible difference in real ether ! Probably, we shall live with LP vs CP troubles for some years and for many it is not as easy to swap it.

The Prague decision was made I think before CP was tested rigorously on 10GHz. The main issue seems to be depolarisation loss, which 10GHz measurements indicate is worse on CP than LP. It seems that the depolarisation effects get increasing more significant as frequency increases, and are becoming noticeable certainly on 10GHz. More info here: http://www.eme2016.org/wp-content/uploads/2016/08/EME-2016-G3WDG-Presentation.pdf I now am able to rotate linear pol very quickly, using a newly developed feed (that is soon to be published in Dubus). I took the opportunity during the contest to see who was using CP and LP , and almost everybody I worked was on LP. The "upside" of LP v CP, as noted in my paper, is that the CP to LP loss is only about 2dB, so you don't lose as much as you think. The paper also notes that for ultra small stations to big station, or small/medium station to small/medium station LP to LP gives better performance (provided spatial offset is small of course). So, for stations deciding to go with CP, you won't lose too much when working linear stations provided your CP is good (ie low axial ratio). I'm not sure how good in this respect all feeds currently in use are. On this basis, I think CP and LP happily co-exist and we don't need to "insist" on one or the other. BTW, re "excuses", I built a CP feed last year that works extremely well, with low loss and an excellent axial ratio, but do not now use it on the air. 73 Charlie > Peter, Vlada > > the fact that using a 2.4m dish LIN Pol can truly random copy CP signal > from 1m dish with only 50W at PA output (net at feed maybe 40W) is a very > strong argument to change to CP for everybody, as decided at the Prague > EME conference long ago. > > Given, the LIN Pol stn would have had CP instead, the signal would have > been much easier copied, all losses by the not perfect CP feed included. > The advantage would have been approx. 2.5dB. > > I made 2 fully random QSOs CP with 1m dish and moderate power.

As we discuss in Italy last year after my presentation. 3cm is so critical for dimensions and accuracy. I will be happy with my V pol for more next years I think :-) About DUBUS contest, as you know I was testing my 10 GHz gear before EME expedition as CN2R in October this year. I was using 180cm dish and 30W RF on the feed. N/F 0,65 dB on the feed. Already worked 20 stations. Everting was working well, including converting to JA band. Just only problem with elevation reader I have to fix, but it is very small project now. Thank you to all for nice QSOs and great fun. I heard during QSOs OF2DG and K2UYH which I did not work. I hope to work many of you from Africa. ---------------------------------------------------------------------------- --------------- 24/06/2017 06:43 HB9Q??????????? JN47CG? O??????? RO??????

On my screen there were at best 7 stations, however weaker than OZ1LPR (8dB anl) and SP6JLW (12dB anl). I started calling SP6JLW first, calling various times - all in all 30 min at least. No QRZ. Then took the second best option, OZ1LPR. Got QRZ after some minutes calling him. 30 min later, my first QSO was fact. I did not believe that it is possible but it came true. So I got more enthusiasm again and restarted calling JLW who finally, after another half hour, sent his first QRZ. When I sent many times my call, I got the report. Then JLW asked for RST, so I sent MMMM for at least 3 minutes.. RRR ended the QSO. Maybe you understand that I did not try to call the weaker stations after all. I was happy and exhausted enough, hi! We will have a QSO next time! By all this it is obvious that skedding would have made everything very very easy. This is one reason I resist to arrange skeds, to enter chat boxes or use internet to simplify EME down to a cheap commodity. 73 Dominique HB9BBD From: vlada [mailto:vlada.masek at volny.cz] Sent: Montag, 26.

Does it mean that you found only mentioned two signals and nothing from us or somebody else like G3WDG ? Good joke with WP, I would prefer OP (Other Polarisation). Maybe, I would remind that already in 1993 (before 24 yrs!) OK1KIR used CP with homemade feed and doubled WG switch ( http://www.ok1kir.cz/index.php?page=gals &gallery=35&galpart=1&list=1&start=0&lang=en ) - see enclosed picture. However, it was actually wasted effort regardless 9 yrs after the CP recommendation was agreed on the 10th EME conference in Prague in 2002 and this CP compartment was even exposed to the participants as an example. Therefore later on we designed the new focus compartment only with LP in 2004/2005. I can personally again repeat my statement that CP is the best solution for contests, but for the marginal tests (skeds) the LP is in favour. Nevertheless how many of us can nowadays easy swap CP and LP without any impact ? So, probably it will take more time to prevail ....... 73, Vlada for OK1KIR (if anybody curious, details on www.ok1kir.cz) ______________________________________________________________ > Od: Dominique F?ssler > Komu: "'freetalk moonnet'" , , "'vlada'" > Datum: 26.06.2017 14:18 > P?edm?t: FW: [Moon-Net] [Moon] Test > Peter, Vlada the fact that using a 2.4m dish LIN Pol can truly random copy CP signal from 1m dish with only 50W at PA output (net at feed maybe 40W) is a very strong argument to change to CP for everybody, as decided at the Prague EME conference long ago.

Wkd JA4BLC twice, heard Yoshiro calling CQ for a very long time and no takers so called hem for a second time ;-) Was very happy to work 4 initials. The strongest signal over the weekend was SP6JLW !! It was very easy to see on my waterfall where SP6JLW was calling did not need to tune to that QRG and listen. Also OZ1LPR, YO2BCT, JA4BLC and G3WDG had a big signal. Smallest station i worked this weekend was OK1DFC running a 1.8m PF dish and 30W, great job Zdenek. Wkd K2UYH on 3cm for our "7th band EME QSO" The first EME QSO we made on 432Mhz in 1987 and now 30 years later on 3cm ;-)) Wkd: JA1WQF, JA4BLC, JA8IAD #50, JA4BLC 2nd time, SP6JLW, HB9Q, OK1KIR, OF2DG, OZ1LPR, OK1CA, HB9SV, HB9BHU #51, OK1DFC #52, ES5PC, IK2RTI, YO2BCT, PA?BAT, DL7YC, K2UYH #53, WA6PY, G3WDG and VE4MA.

It is a Channel Master/Andrews 2.4M offset dish with a F1OPA preamp. This gives 1.1dB moon noise and 14.1dB sun noise. Heard on CW OK1KIR, OZ1LPR, HB9Q, IK2RTI, SP6JLW, PA0BAT, DL7YC, and DB6NT. ?Detected ?WA3LBI & G3WDG on JT4 but had finger trouble with WSJTx so couldn't decode them. Already I have resolved a mechanical problem with the dishes autotrak and I am aiming to get a 15W PA installed at the feed. 73sDougG4DZU From vlada.masek at volny.cz Mon Jun 26 15:40:40 2017 From: vlada.masek at volny.cz (vlada) Date: Mon, 26 Jun 2017 15:40:40 +0200 Subject: [Moon] =?utf-8?q?=5BMoon-Net=5D__Test?= In-Reply-To: 000000002d81003f69540062fe6d References: 000000002d81003f69540062fe6d Message-ID: <20170626154040.E3A37131@volny.cz> Hi Dominique, sri, a question repeated. Does it mean that you found only mentioned two signals and nothing from us or somebody else like G3WDG ? Good joke with WP, I would prefer OP (Other Polarisation). ? Maybe, I would remind that already in 1993 (before 24 yrs!) OK1KIR used CP with homemade feed and doubled WG switch ( http://www.ok1kir.cz/index.php?page=gals&gallery=35&galpart=1&list=1&start=0&lang=en ) - see enclosed picture. ? However, it was actually wasted effort regardless 9 yrs after the CP recommendation was agreed on the 10th EME conference in Prague in 2002 and this CP compartment was even exposed to the participants as an example.? ? Therefore later on we designed the new focus compartment only with LP in 2004/2005. I can personally again repeat my statement that CP is the best solution for contests, but for the marginal tests (skeds) the LP is in favour.? Nevertheless how many of us can nowadays easy swap CP and LP without any impact ? ? So, probably it will take more time to prevail ....... ? 73, Vlada for OK1KIR (if anybody curious, details on www.ok1kir.cz) ? ? ? ? ? ? ? ? ? ______________________________________________________________ > Od: Dominique F?ssler > Komu: "'freetalk moonnet'" , , "'vlada'" > Datum: 26.06.2017 14:18 > P?edm?t: FW: [Moon-Net] [Moon] Test > Peter, Vlada the fact that using a 2.4m dish LIN Pol can truly random copy CP signal from 1m dish with only 50W at PA output (net at feed maybe 40W) is a very strong argument to change to CP for everybody, as decided at the Prague EME conference ?long ago. Given, the LIN Pol stn would have had CP instead, the signal would have been much easier copied, all losses by the not perfect CP feed included. The advantage would have been approx. 2.5dB. I made 2 fully random QSOs CP with 1m dish and moderate power. Already 1.2m dish would improve another 3dB. Btw: I like "insane" power? by others, it enables me to copy them even with small dish and WP "wrong Pol") I think time has come to go CP. No more excuses. 73 Dominique HB9BBD ?

Hi Peter, very well, you touched everything, so I have nothing to add to. Looking for another "insane" beacon power from you on 6cm !

I have also given the CP/LIN some thoughts and I get by using V pol and? twist in case of need. Problem is no one get their CP Feeds near the performance of Lin feeds. There are additional losses in the CP feeds. Furthermore when one design a feed it is almost not fitting 100% illumination wise. Specially in Offset dishes that can be felt. Also dimensions are quite critical on 3cm making a good Circular Feed. I would need a waveguide Feed for Andrew/channelmaster dish. I am sure it will be hard to get all to agree on the topic. ? Agreed power is insane at JLW and at my Station. Well my TWTA is a Class A TWT and does like making max power out in the feed. Otherwise it is just dissipated in the TWT. It draws 3000W from the 230V when PTT. It delives around 750W on the flange but big loss in feeder system. ? Why alligator power ???. Well it makes everybody able to hear a signal from the moon same as the Beacon but only better as there Is actually a person behind. I try to infect as many as possible to this challenging part of our hobby. Hearing a signal from the moon makes them want more. Even my own kids are very amazed when I let them say a few words and hear them back from the Moon :o). ? Vlada it is stations like you that makes the band a success as it is always possible to work you. ? By the way soon I be QROO on 5.7Ghz also I just got the Waveguide feeder so will make 500W where around 300W will hit my Feed horn that actually is CP :O) Have a nice day both of you. 73 Peter LPR ? ?

Hi Dominique, first sincere congrats to 1st CW 3cm QSO. However something still to think about as the both OZ1LPR and SP6JLW have huge TX power. Have you ever found ours 50W signal during the contest ? FYI, we made 32 CW QSOs. E.g. we made also random CW QSO with OK2AQ with 1.2m dish and similar power (close to 50W at max) at spread of 120Hz, but with linear polarisation ! Seems, these 3dB is terrible difference in real ether !? Probably, we shall live with LP vs CP troubles for some years and for many it is not as easy to swap it. ?

Only one CW QSO this weekend, with OZ1LPR, tks for hearing me Peter. Furthermore some TX drift is a good indicator that I need to assemble the OXCO kit laying on the shelf and install it in the transverter box. Besides OZ1LPR, I heard SP6JLW, IK2RTI, PA0BAT, OK1KIR, YO2BCT, PA3DZL, OF2DG, DL7YC, DL0EF, HB9Q, WA6PY , VE4MA and G3WDG. Heavy rain on Sunday did not help either, moon noise dropped considerably. Using a 2.4m prime focus dish, and the label on the amplifier says 19 watts output. Not sure if that is correct, I have no means right now of measuring power on 3cm :-). Moon noise peaking at 1.2 dB on Saturday when it was not raining. Preamp NF measured by HB9BBD to 0.9 dB (tks Dom). During the ARI contest some weeks ago I listened briefly on 3cm and heard SA6BUN, N4EME and PY2BS. As always with me and my equipment, plenty of room for improvements. I might get there in/before the end :-) If it was easy we would not do CW EME... 73 Peter SM2CEW From brian-coleman at tiscali.co.uk Wed Jun 28 10:52:44 2017 From: brian-coleman at tiscali.co.uk (Brian Coleman) Date: Wed, 28 Jun 2017 09:52:44 +0100 Subject: [Moon] Possible 3.4Ghz Activity with 32m antenna Message-ID: Hello Folks If all goes to plan I will be doing some tests on 3.4GHz using the 32m antenna GHY6 at ?Goonhilly Down? loc IO70 on Thursday 29th.
