Hi,
Does anyone know where I can buy a replacement transmitter
board and/or PA for an Icom RP4020 UHF repeater.

Please help me identify this unknown 222 TX and RX. It was donated gear, so
if you're just going to tell me to throw it away, please be prepared to
donate something to replace it.

This looks like an old VHF Engineering repeater. Popular in the 1970's.
I had one each on VHF and UHF. Not bad for the price and vintage, but
a bear to keep stable. I no longer have any docs on the stuff as they went
with the equipment when it was sold. As I recall, the tx was about

That is definitely a VHF Engineering repeater, made from a kit. You
can download the manuals for these repeaters from several Web sites.
Here's one:

The radio is working fine and controller is known good.
Have not been able to make interface.

The power amp board you have isn't VHF Engineering. Their power amp is
on a PC board about the same dimension as the transmitter.
It looks identical to the power amp in our 440 machine, which was
from hamtronics.

Not really any better (or easier) to convert to a Ham repeater.

I also recall low band Micor's being equipped with an extended receive
option - worked so the county sheriff (on 39 MHz) could receive the State
Police (on 42 MHz)... That added an extra section to the drawer, just like
you described.
Sorry if the model number given wasn't for a low band radio
It's VHF but who knows Maybe it's one of those for high VHF.
I'm going to pursue making a 222 repeater out of it. After I tackle the
UHF conversion.
I'll take some pics of it on Sunday and upload them to the files section.

Not as a repeater. The duty cycle is only 5%.

Joe,
Found the book, there were two of them. One says 14% and the other says 20%
duty cycle. I looked in the schematics and sure enough it has only one
synthesizer. Would be nice if there was two, guess GE saved a dollar or two
on the cost.

And why not? No need for two synthesizers in a mobile. In fact, I can't
say I know of any mobiles that use two. The base station may be 20% with
the fan. I'm pretty sure the mobile is 5% (no fan).

I just re-read your original post. I assumed it was a RANGR you had. Is
it a DELTA-S or DELTA-SX? If it's a plain DELTA, those are crystal and
can be converted to a repeater, but the duty cycle still isn't adequate
for repeater use.

Joe,
Are you saying that the offset oscillator can be strapped to continue doing
it's job while the receive is still working? Most synthesized repeaters I
know of have two VCO's, may have not used the correct terminology there when
I said synthesizer. Sorry bout that!!

I just bought the Hamtronics TD-5 Encoder/Decoder to install in my

confused with each
Yep - and it's a good one too. It has the optional narrow filter in it. I have
a manual for it I believe. Used to have one,
wasn't all that bad actually. Repeater audio sounded good. I think I still have

Joe,
The wall mount book LBI-31453D says to refer to the mobile book which is
a Rangr 403-512 MHZ book, LBI-38181 if that helps.
Like I said, just hoping this would work as a temporary repeater to get me
by till I can get the crystals ordered for some Mastr II equipment I have.
Thanks,
Paul
No - I'm saying in a mobile there is no need for duplex operation, so
why not '(save) a dollar or two on the cost' when you're not affecting
the operation of the mobile? There was no need for two synthesizers, so
you can't fault them for not designing it with two.
Yes - most REPEATERS have two.
I know it's not a repeater, none of my repeaters were repeaters before I
made them repeaters.
Never mind,
Paul

You're not understanding what I'm saying. You said (still quoted at
bottom) Would be nice if there was two, guess GE saved a dollar or two

It's not fair to blame GE for there only being one synthesizer. It's a
mobile (or a base in your configuration). It's not a repeater and was
OK - so it's a wall mount RANGR - actually, a wall mount RANGR 450.
Those have very low duty cycles. Again, they may have increased it when
combined with the fan. Still, not good in any respect for repeater use.
If it's that big of a deal, get the crystals on an emergency basis (48
hours). You
