Hi all-
There's a better than 50/50 chance I'll have my station up and running  
on 3456 (NOT 3400 yet) by this weekend.

I'd like to know who's planning on being on for the activity period  
that I might be able to work.  I don't think it's wise to make any  
skeds at this point, still too much that could go wrong between now  
and then.  But if you'll let me know when you'll be around, I'll have  
something to shoot for and maybe tail-end.

My station is as follows:
5m solid dish with linear feed (commercial Chapparal-style feed  
designed for this dish- illumination should be near optimum)
60W SSPA (tested last night) at the back of the dish- est 50W at the feed
0.7dB NF LNA (unless I can get something better going before the weekend)
DEMI transverter (old style)
Tracking camera to visually track if the sky is clear
EA4TX tracking interface, F1EHN tracking software regardless of the  
sky conditions
I should be able to be linear either H or V, the feed supports this easily

Note:
I have not measured Sun noise yet, I only got the tracking going last  
weekend.  I have still to build a WR229 to coax transition to get the  
signals in/out of the feed and verify my tracking calibration by  
measuring some Sun (and hopefully Moon) noise.

I hope to hear from you and I definitely hope to work some of you this  
weekend!  It's been too long since I was on 3456 EME (Spring 1987),  
much less EME in general.
