[TenTec] Orion 2 Firmware 2.044A PTT

I just got my Orion 565AT back on line after the DSP board serial port died
on me. Turns out the chip capacitors that produce the negative volts had
gone bad. Ten-Tec kindly fixed the board I had shipped to them and even more
kindly charged me $140 for the fix but I'm far from complaining, indeed I'm
so delighted they would take just the module, that's a radio company I can
work with.

Having got it working I thought I would have a look at the AM transmit
signal. Bear in mind this is a 565 not a 566 but likely similar in the way
they do AM. Just on a power meter, not got it hooked to the service monitor
as yet. Key down on AM it reads about 16 watts on a Bird 43 but with speech
the Bird rises to about 24 watts. The Bird 43 does not respond to the
modulation, only the carrier so it seems likely that some sort of controlled
carrier is being implemented.

80 watts to 100 watts is about 0.95dB, Accounting for metering variations,
modulation variations, temperature, moon phase, galactic mass ion shift, I'd
say (maybe) near enough. Watts(sic) 0.95dB amongst friends?

Martin, HS0ZED

I'm seeing 14.5 Watts with no modulation and mod peaks 60 to 80 Watts.
