[Moon-net] 3.4GHz EME - DL4MEA

[WARD,AL]

Hello
I would tend to agree that shooting for 3400 MHz would be better than 3456 MHz since it does appear that all countries who have 9 cm so far can operate down at 3400 MHz. US and I believe Canada as well have 3300 to 3500 MHz but 100% of all terrestrial activity in North America is at 3456 MHz so getting new blood in the US to migrate down to 3400 MHz by building an entirely new transverter except for the LNA might be a tough task. I have separate transverters for 3400 MHz and 3456 MHz and I expect to keep both in operation. I would also agree that cp is the way to go. I struggled trying to get the customary polarizer screw type feed to have good return loss , isolation, and circularity on both frequencies so there is no doubt that the septum feed would be the way to go in the future in order to cover both parts of the band. In the US, WA9FWD and NA4N operate at 3456 MHz and I believe are linear. I would be interested in their thoughts about moving to cp on 3400 MHz.
It was a fun weekend but I still have feed work to be done. I was able to work G3LTF on both 3400 and 3456. and I also worked G4NNS, OK1CA, and VK3NX on 3400 MHz.

Hello Ed and others,

let me quote first:
"I will only need to build a feed and get a LNA for 3456."

quoting G3LTF
"worked  on 3400MHz
VK3NX, OK1KIR, LX1DB, G4NNS, 
cross band
VE4MA
on 3456MHz
W5LUA, OK1CA (@mea: I believe OK1CA can do 3400, too)

Might it be that the majority of the activity is on 3400MHz and so we can agree that 3400MHz is the primary goal of 9cm EME?

I am currently fixing the problems of 23cm and 13cm, but I have all parts at home in order to become QRV on 9cm. And I know how complicated it is to have three bands on 13cm. As long as there are just a few ones QRV, this might be a chance to create a norm.

BTW, I measured 11dB sun noise on 23cm recently without having the feed perfectly in the focal point. This is nearly 4dB more than during that frustrating contest, so there is definitly some progress.
