[NLRS] Looking for 902 and 1296 Skeds for Microwave Sprint this Saturday

[Zack Widup]

I hope to work you Lloyd. I am most likely going to start out somewhere
around EN51mr around 7 - 7:30 am and then move to EN52sa. I should have a
good shot from EN51 but the hill in EN52sa isn't so good to the north. But
we'll see. I should have 902 thru 10368 with me.

I made a modification to my 902 transverter. It's the original KK7B design.
The original design used two MAR-6's in the receive chain. That's 40 dB of
total gain minus the filter losses. Adding a LNA preamp seems to produce way
too much gain and I finally figured out all I'm doing is amplifying noise.
The IF rig always had at least S9 noise in it. So I removed the first MAR-6
in the transverter and replaced the one between the hairpin filters with an
INA-10386. On the bench, the noise is now S0. However, there IS an increase
in noise when the transverter minus preamp is turned on and another noise
increase when the preamp is powered. Hopefully it will work better now.

73, Zack W9SZ
