Steve,
This won't be a solar power application. They want to get the power draw down
to around 3-4 amps to reduce the size of the power supply needed. Rather than
have a big Astron sized unit, they want to use a smaller switching supply. In
addition, the RF output only needs to be a few watts
I'd be very interested in hearing from someone who has used the
standard version of this, particularly the audio spectrum analyzer. I
have been using the limited version of Oscillometer, but a 15 second
run time doesn't cut it and I can't afford the $400 plus price tag.
Thanks,
Scott Madison,
Anyone have any experience with a 450 MCR 100 Desktop repeater??
What does it take to program it? I have the manual.

I don't know if I would call the MCR100. It is a wall mount similar to
the Radius R100.
The freq and PL/DPL are programmed with a computer and programming cable.
However the choice of either PL or DPL is determined by firmware in the
repeater.

You should make the cable 11-12 inches long, like the
manual says. I made mine 6 inches before looking at
the manual or the chassis - way too short. Now I have
to take it all apart and do it all over again. #22 or
#24 stranded wire is fine.

Ok, I wasn't thinking in this direction before, but I do have an audio
band spectrum analyzer handy.
Question is, how can I translate this to a Sinad measurement?
Looking at the receiver in question now, the second harmonic of the
1kHz tone is -40dB, and the noise is at about 5dB below that.
It sure makes a difference when things are designed for low power.
My whole daniels rig, receivers and transmitters for 2M and 440, draws
about 80mA at idle. I have a mobile radio that I use for a control
link, which draws about 300mA at idle.
In the daniels, there's a lot of attention paid

I recall reading somewhere that the SINAD measurement
is the residual signal after the 1kHz tone has been
filtered out. Assuming you have a full-quieting input
signal with 3kHz deviation and you've notched that
out, there snould be nothing left to measure. As the
signal gets noisier, the harmonics

Right
When that level gets to 12dB
below the no-signal noise level, you've reached the

OK, thanks for the input, Bob. I actually measured the cable I have, and it
measures about 7 1/4 overall... So 6 would have been a bit short.
I'm wondering just how critical the shielding is on this particular cable?
I have multi-conductor cable available, but it is unshielded.
Mark - N9WYS
Well, it's only metering signals, and I'm pretty sure
they're DC and filtered on the receiver, so shielding
is just part of the overall effort to keep RF inside
the chassis. I doubt it's critical unless you're using
the receiver in a situation where any leakage of any
kind could be picked up and

Wouldn't the SINAD be the distance between the 1kHz tone Spike and

I'd think it might, but the AC voltmeter is measuring
the average (or RMS-calibrated) signal that remains
after the 1kHz tone has been removed. I suppose it
only has to be attenuated by at least 12dB (probably
more) so it doesn't contribute to the rest of the
signal. But if the 1kHz tone level is

I assume you mean distance in amplitude.
Not quite. I think the noise would have to be summed over all frequencies,
including any harmonics of the 1 kHz that get generated as a

I checked the manual for my HP 334A Distortion
analyzer. The notch filter in that unit seems to be
capable of 80dB, and the bandwidth is quite narrow,
under 0.01%. This unit just removes the fundamental
and measures whatever is left.
I found several good articles and explanations of

I don't know if this helps, but the UHF manual says to replace Q203
with L217, which couples the output of Q202 to the antenna switch. I
haven't found a value for L217 yet. This should give you a 2 to 5 W
