Hello,
During a recent move (hope to never do that again) I found a Motorola UHF
duplexer from a MSR2000/MSF5000 100 watt repeater. I don't need it so if
anybody would like to buy it for $150.00 plus shipping, contact me off

Thanks

Depends upon your terrain. If you are in the flat lands I would suggest
the 420. Otherwise I would use a 408.

Just for notice, I have changed my call from W9MWQ to N9LV since I

They are going to switchers though, it's finally come to the place

One nit-pick: measure the actual AC line voltage and use it
where Joe has "115v". Locally it's 118-123v, depending on
the local load (i.e. lower on a summer day, highest during
a winter night).
And sometime when you have a free hour, wander around
the house and count how many wall warts you have

K-55's on X band are still very much in use in New Jersey, which, at one
time (maybe still) had the highest per-capita number of radar units in
service. NJ state law still requires X band radar for the State Police!
They're still using most of the units that they bought when the national 55

The easiest way to tell would be to measure the AC
current draw in idle. Then measure the DC current draw
in idle.
You can get a pretty close watt figure by multiplying
the amps times the voltage (115v) on the input side,
and doing the same thing on the DC side. The
difference between the two is y

I've got a Motorola VHF 1/2-kilowatt base station here (1974 vintage)

The cabinet has been gutted to hold a new repeater transmitter, but

Hello Jeff,
How is the fc determined with the UHSO is a crystal still

I have a 902 spectra Rx for the uplink and a 15 watt Micor high band

I am going to use this for a fill transmitter for a ham box in the

This thing works but the station control / power supply has

Carefully consider expanding into switchers. The designs are quite
varied. To repair them you really need a good high frequency scope,
shielded isolation transformer, 0.18 ohm 1000 watt resistor load,
and most of all a good schematic. Switcher parts are hard to find

I am trying to build a repeater, for the 2m Ham band. The Micor I have now is a vhf repeater that was used in the 138-142 mhz band. I currently have no modules for this unit, however I ordered a Station Control Module but by what you are saying I need to order a Squelch gate module as well.
If you are looking for a good multi-repeater/link repeater Link Com has one with lots of bells and whisles. Think one will handle 4 repeater or links.
