Just putting the shack back together and I'd thought I would check on the
progress of an issue I reported on May 2 2008 regarding transverters. At the
time I elected in fairness to make it a feature request however this time I
decided to bring it up here since the feature request system is quite obviously
no longer managed. This time I have looked more thoroughly at the function and
I am quite concerned at what I have found.
Attempting to operate crossband results in unintended emissions on
inappropriate frequencies:-
Example:
VFO A 50.500 [TX]
VFO B {VHF0, 144.500}
Transmit = normal behaviour. Next split.
VFO A 50.500
VFO B {VHF0, 144.500} [TX]
Transmit = 28.500 at full output at current drive level. TX meter registers 0
watts. This could potentially lead to someone driving 100w into an empty
antenna connector while trying to elicit some RF from their transverter.
Next, exchanging the VFO's and with TX on VFO A, everything is normal. With TX
on VFO B, there is no RF output. This fortunately has no potential for harming
the radio (providing you discount an irate op with a chainsaw) although it is
deeply frustrating. The first example however warrants prompt attention since
the best case scenario is obliviously transmitting on completely the wrong
band. The worst case scenario potentially involves smoke and swearing. . .
I would be grateful if someone else could corroborate these findings, although
I have just re-tested with a clean database with no change to the results above.
