Hey Mike, thanks man. i didnt find anything but out dated info when i searched
out the internet on this and right now i dont have any equipment up here so i
cant even get up on a local 2 meter repeater or anything. i just got done
leaving william a voice mail and perhaps i'll send him an email
at the moment, funds are tight. hell, i dont even have a rig right now. so i
really cant afford to spend the money on gas to go to california. thanks for
the idea though.

Hi group,
I have an old duplexer Q202 without harness and I want to transform the
pass cavite into Q Filter, with a piston capacitor in serial with the
loop.
Maybe someone in the group know the range in pF of this capacitor for
VHF ham band?
My freq. are TX 147.165 and RX 147.165
Thank you
Dear RP,
I am doing some testing and have the 145.410 repeater connected to a
dummy load. To get an accurate output indication in watts is it
critical to have 1/2 wavelength cables? I have used an 18 cable from
TX to wattmeter and then a 72 cable from wattmeter to load resistor. I
have noticed
I am running a Diamond X-200 with a MFJ-916 diplexer on 146.850 and
443.050 with excellent results. The VHF makes about 50 watts the UHF
30. I tested the diplexer with a 5 watt bird slug while transmitting
100 watts into the opposite port, before attempting the configuration.
Both repeaters also

If you can find a manual for a bird wattmeter, they had a chart in the back of
how long to make cables to go with the meter for different freqs.
With this setup, you could insert it in a system and after tuning remove the
meter setup and still have it balanced.

Well, Gerald sent me the schematic for the Master Decoder modules I have. I
compared connections on the card I have (thanks to his schematic) against
what the newer card provides. Here are the comparisons:
Pin 1 - Ground = OK
Pin 2 - PL Tone to Modulator = OK
Pin 3 - To Audio

Hi John,
The active high/low label applies when the circuit or device
is actually on. On meaning the state of the logic... not just
power supplied to the circuit.
The output of a typical logic circuit, gate or device is at
or very near ground or zero volts when it's on... active low.

the air on 444.250/449.250. I still need a duplexer and feedline. If

I build my own diplexers. This way I can insure that the components are
suitable for the power level used.
The 440 side is built in typical antenna tuner fashion with a series variable
cap, a shunt inductor and a series variable cap. Adjust the caps to provide a
1:1 SWR at the operating

Our club ran a Larson diplexer on our 30 watt repeaters for years with no
problems. I'd pick one that doesn't have coax tails that may be of
questionable quality. Have separate antennas and feedlines now.

no joke; got an inquiry for 10-12 vhf duplexers 150-174 4 cavity pass/reject
similar to those in VHF micor repeaters and MSR2000 repeaters.
state qty and price in 1st email or call me at below phone days 0900-1800 cdst.
will also consider Phelps-Dodge 6 cav reject types in 19 inch rack mount.

Kevin,
I've been meaning to postabout a similar project, and this prompts me
to ask - have you done this to rebuild a UHF amp?
I have not, but there is no reason one could not. There is 2 watts

I am not sure what would make a good or not good load resistor. I am
using a pair of non inductive 100 ohm 100 watt resistors in parallel,
air cooled. I also use a cantenna. Are these not good or fair?
Thanks, Collin

Colin, Non inductive resistors are quite inductive above 30 Mhz.
The Cantenna is also a poor load at VHF / UHF.

John,
Very well then, I guess I need to be shopping for a good load. Any
suggestions? Any under an arm and a leg? What do the good loads use for
a resistor? I was under the impression that a non inductive resistor
was the purest resistance you could get. I have been wrong many times
