W1TR Main Station

[back to W1TR Home]


The primary operating stations:

ICOM IC-756 Pro 3 + Collins 30L-1 Emtron DX-3 + Palstar AT5K, and

ICOM IC-765 + Amp Supply LK-500ZC + Heathkit SA-2500 Auto Antenna Tuner + various Collins 312B-4 speakers.

The computer is a little Dell 433 Pentium (soon to be upgraded) + 17 inch ViewSonic VA721 flat panel monitor.

The computer controls the rigs via the RigBlaster Pro and Icom CT-17 communications interface.


The 30L-1 is not really all that necessary, but the Emtron doesn’t cover some Government Emergency Service frequencies
and takes a few moments to warm up, whereas the 30L-1 is an “instant on” since it uses 4 x 811a tubes
(too bad it doesn’t work on 160 meters!).  It comes in handy sometimes while waiting for the Emtron to warm up!

Here is a picture of how the operating position tables were constructed, from solid doors and PVC toilet pipe.
They are quite sturdy!  And they have wheels so you can move them to get at the wires in the back!

(all parts are readily available from Home Depot / Lowes, etc)
