I have a TWT CPII mod. VTA-6193C2 and, I am looking for the original power supply, also not working. I'm not sure but I think the power supply code is VZK-6901 ?? If anyone had one and wanted to sell it, they can contact me. Thanks in advance for any information about it.

Message-ID: <80976110-b64e-3f07-833b-728b83f06995@wannberg.net> Hello all, Less than three months before my 13cm high power permit elapses (probably for good), the 108 MHz oscillator that is the heart of my LO system has gone bad. It is a Vectron model 228-5354 OCXO that has worked perfectly for 11 years; it has usually stabilised to better than 10 Hz off 108 MHz in about 30 minutes and then stayed put for weeks. But last week I lost a sked with F2CT for no good reason and it was only after getting the counter out that I found that the LO frequency was off by about 1100 Hz and moving around erratically by some 5-10 Hz. After mixing with 12 MHz and multiplying by x18 this translates to an offset at 2176 MHz of about 20 +/- 0.2 kHz. BTW, the system also generates a 117 MHz signal (108 + 9) that will be used as LO1 injection for the 6cm DB6NT transverter under construction. There the offset will be almost three times as great, so it had better be fixed... The OCXO case is not warm and the frequency vs. time curve does not follow the normal pattern, so either the oven control system and/or the heater are faulty. But I don't want to risk opening the unit now - it is in a metal case that is soldered shut and will have to be opened with the aid of a gas torch at the risk of totally ruining the oscillator proper... So now I am looking for a working 108 MHz OCXO as a quick fix, preferably an identical Vectron unit but any 108.0000 MHz OCXO should work. I have scoured eBay and a number of surplus dealers' websites with no luck. If anyone happens to have one that you can part with or if you know where to find one, please email me directly at sm3bya AT wannberg.net!

Many folks trust the construction of the connector to keep it weather title. I never have and always put a layer of Scotch33 covering everything and out onto the Co-Ax. Many folks will talk about condensation, but I never had anything other than a pristine connector when I open it up. Be sure and saturate the mating parts with the grease Andrews supplies, it helps too. 73's Stephen Hanselman, KC4SW Datagate Systems, LLC 3107 North Deer Run Road #24 Carson City, Nevada, 89701 (775) 882-5117 office (775) 720-6020 mobile s.hanselman at datagatesystems.com www.datagatesystems.com a Service Disabled, Veteran Owned Small Business DISCLAIMER: This e-mail and any attachments are intended only for use by the addressee(s) named herein and may contain legally privileged and/or proprietary information.

HI all: Hope this is an OK request as I know there are many on here who have likely used, or are still using, these transverters. Any repair experts out there who have dealt with these? I have had the LT-6 through LT-70 for many many years, without issue, though none have been operational since 2007. Yesterday I fired up the LT-2s and was pleased to see it working fine with adjustable output up to 20w, as it should. I set it for 10 watts out as was looking to run an on-air test with a new local ham. I then inserted a new-to-me wattmeter in line with the Bird 43 to check it out. Odd that the Bird was reading 20 watts now......hmmmm...I didn't twig fast enough and suddenly lost all power output. Turns out one of the connectors on the 2nd wattmeter was not screwed all the way in and was open - hence the high reading on the Bird. And now there is zero output. My bad! I do have low level 144 Mhz RF going into the PA, but nil coming out apparently. I can see the strong signal at 144.200 on a nearby SDR rcvr and it gets much stronger with an antenna wire brought close to the PA input. I am really hoping the final transistors are not toast - seems odd that transistors supposedly rated at 50w would die within 5 seconds at 10w out into an open line! I am hoping it is one of the other small parts in there that smoked instead. Either way, I need to pull the PA board, which is not going to be a simple task from the looks of things.

To be used on 10 368 EME It could be the answer to improve the stability of some of the LNB to receive & find the DL0SFH beacon?? The website is ZachTek.com then go to shop.

I worked 8 stations on Saturday and 6 on Sunday. Some of the stations worked Saturday I was off on my elevation a few degrees but fortunately eventually figured it out. I was using a recently setup SDR scope to find CQ callers which was very helpful. I enjoyed hearing all of the CW activity. Currently I get the moon from the first half upon moonrise up. I have offending tree limbs in the way afterwards. I have a tree trimmer on schedule to remove them so I’ll have zero blockage but he may not be able to come out until early October.

The encoders can only be purchased in lots of 10 items, and Dirk needs to know, if eventually there is any interest in these encoders throughout the community, adjusting the numbers for an order at Megatron. Costs will be roughly 50 Euros per item, not yet finalized.

Condx for NA (I cut several trees in front) seemed to be very good and had good echoes, while the EU window seemed a little noisy (+1dB), in spite that I already cut down hundreds of trees in the neighbor area (of my property). Thanks for the QSO's to my old friends, and new ones, DG5CST #142, VK2JDS #143, IK3MAC #144, and OH1LRY #145.

After getting Bob's permission, I am sharing in the hope that others will find this as useful as I certainly have. Thanks so much, Bob!! Serge VE1KG The LNBF is the easy way to do RX I think. You can get a transverter, but it will have sma connectors. You have to get a signal from and LNA at the feed to the transverter, and any coax will be lossy. Waveguide is better, but the "plumbing" is harder. Waveguide is rigid and will not bend. You can get flexible waveguide, but it's harder to find and probably more lossy. You can buy a preamp that has waveguide input and coax output (around $200+), but you still have to build/buy a feed (see for example https://www.rfhamdesign.com/products/dish-feeds/offset-dish-horn-dish-feed/i ndex.php), and the coax from the preamp to the transverter has to be short. UT141 coax (normally used with SMA connectors) has a loss of 45dB/100ft, so you wouldn't want to run much more than a few feet of it between the preamp and transverter (depending on the preamp gain). Using larger cable may not be practical due to multimode propagation at the very short wavelength. This means you probably need to mount the transverter out at the dish rather than in the shack. You can get coax in and coax out preamps ( https://www.downeastmicrowave.com/product-p/l3-2ulna.htm), but then you have to run coax from a coax output feed the preamp. Evert ft of UT-141 will increase your NF by 0.5dB, plus each connector may add another 0.1dB. The advantage of the LNBF is that it's small and light, there's no external 10Ghz connections to make and cable loss at the 618MHz IF frequency is much lower - plus the LNBF has so much gain that cable loss of 10dB or more won't affect the system noise figure. The disadvantage is you have to use an SDR and figure out tracking and coupling to WSJT-X. That's a bit easier with a regular rig, but most rigs won't tune to 618MHz. And of course you can't transmit, though to make any contacts with a small dish you'd probably need to generate 20-50W of power, and even then you'd only work the larger stations. Rather than an SDR you can use a 618MHz -> 2m converter. There's one here - https://www.ebay.com/itm/618-145-MHz-10368-10-GHz-RECEIVING-CONVERTER-3cm-10 -368-shf-uhf-vhf-/223963858149 - I have no idea how well it works, how stable it is etc., but 618 to 145MHz isn't difficult to so, so I suspect it probably works OK. My main concern would be the stability of the 473 MHz oscillator module that they use for the LO. I suspect it's a simple OX module. 1ppm drift of the IF would give you close to a 500Hz drift of the converted signal and these things can drift from 10 to 50ppm over a large temperature range. I suspect it would be good enough to get you within 1kHz of 10368 and the drift rate (indoors at a constant temperature may be good enough to allow decoding of signals. It would be better with a VCTCXO frequency source, or a synthesized signal based on an OCXO. I don't know any commercial converters like that though. They'd probably be too expensive and you wouldn't expect a very large market for them. This one looks like a cheap and simple way to get 618 to 145MHz conversions and would be an alternative to an SDR of you already have a 145Mhz radio. 10368 would probably then be found in the 144.95 to 145.05 Mhz region. It probably wouldn't be exactly at 145. So then you'd go 10368 -> LNBF -> 618 -> 618/145 converter -> 145 radio -> PC/wsjt-x Hope this gives you some ideas Serge. Your trip to PEI sound like fun. He in Maine the covid-19 situation is pretty good. Certainly much better than many other parts of the US. We are both lucky to be in relatively safe areas. 73 Bob, KA1GT From ea6vq_ml at dxmaps.com Sun Jul 26 18:52:15 2020 From: ea6vq_ml at dxmaps.com (Gabriel - EA6VQ) Date: Sun, 26 Jul 2020 18:52:15 +0200 Subject: [Moon] M2 reseller in Europe?
