[Moon] VE4MA Results for Microwave Contest

I have to echo what Barry mentioned about the libration on 13cm. Wow.

I was on Sunday morning RX only for a couple hours and heard numerous 
signals clustered from 2304.100 to 2304.110. Couldn't locate ANY signals on 
2320.1 at that time; just lots of birdies.

But the 2304 signals were darn near impossible to copy. I kept getting just 
pieces of calls and many single letters and numbers. Normally, on an 
activity weekend, these stations would be on the loggers which would help to 
identify them. But of course with the contest rules actually being followed 
quite well; I got no help from there at all. Finally identified SV3AAF who 
no one else seems to have mentioned in their reports yet.

After awhile, HB9Q posted his calling freq. on 2320.104 and he was so strong 
that I copied him immediately. Strong enough that even SSB would have been 
possible. (soon I will try to hookup my TX also)

BTW, I was using a linear feed, VE4MA style that I built in the 90's. Still 
cannot get my septum feed to work right.

So, it was great fun once again.

Mr. Murphy also visited this QTH, he had a busy weekend!

On the first night I had high RX signal loss coming from the 6 cm dish and a 
bad relay control cable going to the 13 cm dish ( so no TX), but did hear 
WD5AGO and SP6OPN very FB.

On the second night after fully checking out the systems I had better luck. 
On 13 cm I did QSO OK1CA, K5GW, K1JT, WD5AGO, OZ4MM, G3LTF, DF3RU, HB9Q, 
WA6PY, with SM3BYA and OK1KKD heard.

I got on 6 cm briefly and did work SM6FHZ but did not complete with DL7YC. 
I am being heard much better than I am hearing...this is a problem I had 
when portable in AZ earlier this year. I am using the same feed/ preamps 
relays but different rigs in the station. My sun noise is only 11.5 dB on 6 
cm and no moon noise....same 2.4 m offset dish on 3 cm has 16dB of sun. I am 
suspect of the septum polarizer feed and will check with a linear feed this 
week. In the past I had noticed considerable WiFi QRM in VE4 and at AZ, but 
can't say that it was obvious this weekend?

On 13 cm I seemed to have a difficult time with libration....signals were 
strong but copy was difficult....sorry to those who got "many" QRZs from me 
! I was operating on 2320 but had the satellite QRM that Grant VE6TA 
mentioned, and my received echoes were 3-6 dB below what I was seeing on 
2304.  I saw many signals on 2320 but had trouble identifying them.

Best 73
Barry VE4MA
