[GreenKeys] RTTY

[Duncan Brown]

The Antique Wireless Association Museum has just completed a Ham Shack 
addition with multiple stations.  The grand opening of the Ham Shack 
will be on 27 Sep 2023, as part of the AWA Convention.

I have been adapting one of the stations, a R-390 RX & T-368 TX (400W) 
for RTTY with the addition of a MD-239 FSK modulator and a HAL ST-6000 
TU.  I hope to have the AWA Museum station, W2AN, on the air on RTTY on 
Tuesday afternoon.

What is a good 40M frequency to CQ on?

The MD-239 is set up for low space (LSMFT), but I'll be driving it with 
the low-level DC output from the ST-6000 with a switch to select either 
low-Space or low-Mark.

Plan on running 850 hz shift,  but don't know yet if the ST-6000 will 
drive the MD-239 hard enough, so my shift may be a little low. Still 
have to check that out Tuesday AM.

Was planning on rolling in a M28ASR, but found that it has been modified 
with a fixed 2K in the loop somewhere.  If I can't fix it right away, 
will use a M15 (but no tape).  (Have a M19, but it is not on wheels.)

I will give a shout here when I get on the air.

Hope to be able to contact someone on Tuesday and demonstrate it during 
the convention.

Thanks,
