So interesting test.  I didn’t have a ton of time this weekend so I experimented with diversity 2 ways.  I was using 2 CV-483 (the 2 together make an AN/URA-17) Receive only terminal units,  an R-1051 receiver, an AN/URC-58 Transceiver and my KSR.

1. (iTTY) I fed the same iTTY signal into both while set on diversity then cut the audio from each one to see what would happen.  There was a 1-2 character blip but it pretty much kept right on typing with out any issue.  Very cool.

2. (Same Freq, 2 Antennas)I used the RTTY feed from KPH and fed one from the AN/URC-58 and the other from the R-1051.  One was on an E/W End Fed the other on the N/S end fed.  This was more work as tuning took awhile.  Same results once everything was running.  I could detune one radio and it would just flip to the other with no issues.  Another very cool test.

3. (2 Freqs) I attempted to tune separate frequencies but either the KPH transmitter wasn’t working up on 12mhz or the signal wasn’t making it down.  I figure it wasn’t working because I should have heard something from Point Reyes being that its about 350 miles away.

Next weekend I should have more time to test and make a short video on the action.
