[amsat-bb] HF-HF satellite

[Mike Sprenger]

Wow

I remember going to AC4MY's shack and we used his FT-1000D for RS-12 in mode K.  Had to connect the sub RX to a separate antenna....that was the rig I was in awe of then.  

Many used 2 rigs for more K.  There was a great approach in the Amsat journal to use a rotary encoder to tune 2 rigs with one knob.  I almost finished mine to use with all the mono band all mode rigs. As you turned the encoder it would clock the up / down tuning buttons on the mic connector.  The 910h acquisition preempted that project.  

On RS10 RS12 and RS15 mode A, I used a TR-751 for 2m TX and a TS -450 for 10M RX from my truck and those terrestrial antennas provided contacts nicely.  (Pre-dates the Arrow or elk)

 I would stop in a parking lot and tilt the 2M antenna horizontal to radiate overhead.  

That worked well !!!

Going forward: 

If we had a preponderance of mode A or K  the second / other rig could easily be a Radio Shack HTX10 / 100 Ir similar unless those running terrestrial microwave transverters got all of them :)

Thanks,
Mike
