[RTTY] luggable rtty station

[David Hachadorian]

I recommend a pair of TS-850's, powered by a single Astron 
SS-30.

Consider the following comparison of ARRL specs on the 1000D 
and TS-850:

TX power output
1000D  195W
850  100W (I can vouch for this in RTTY so2r contest duty)

Min detectable sig
1000D  -137dB
850 -142dB

Blocking Dynamic Range 80M/20M, w/preamp
1000D 137/154dB
850 141/148dB

3rd Order IMD Dyn Range 80M/20M, w/preamp
1000D 94/98dB
850 100/99dB

3rd Order Intercept 80M/20M, w/preamp
1000D +5/+10dB
850 +7/+7.5dB

I have never seen a situation where I needed more receiver 
than the 850 provides. This includes so2r at 1500 watts, 
with antennas only 6 feet apart, using only two Dunestar 
boxes for isolation. For RTTY, I use the filters 455IF/500hz 
(Kenwood) and 8.8IF/250 Hz (Inrad).
