James,
I managed to tune this duplexer for 2 meter band with RX loss 1.8 TX 2.5

Isolation was about 78db

Eric,
Thank you for the help! Yes, it appears I was reading the pin out backwards
based on a document, that was noted incorrectly!
Also, will order the service manual, was not aware of Pacparts!
Thanks again!

I actually have the same radio, less the mic...
With this pinout, I guess I'll go ahead and use a Maxtrac mic to retro it on
there :)
Thanks!

I inserted a small 20 watt PA after the TX port on our Hamtronics
REP-200 UHF machine.
Repeater puts out 7 watts into my Termaline after all the filtering etc.
With the amp, output is 15 watts, 3DB gain, however the signal on the
air seems weaker.
Its not a desense issue - I can still

Who makes the PA? 20 watts... It probably has a nominal drive

I sounds like your amplifier may be spurious. Your watt meter may be
reading 15 watts, but not all the power being read is on the output
frequency. Watt meters are broad banded, you need to look at the output
of the amplifier on a spectrum analyzer.

Thank you skipp.
Money is not an issue really.
the repeater belongs to our club. Its in between homes now.
You are correct about the LPA. I was looking at the schematic for
that - figured I could maybe swap out the transistor for an MRF (or
similar) that might do 2 in, 25 out and avoid the

Well, cheap is no problem - easy to use is another story. grin
Seriously, there is one program I use that is free, but there is a bit of a

Over the last couple of years several people on this

the schematic to the Radio Shack test amplifier (model

The Shack used to have a schematic on a sticker

I am appealing to the gurus here for assistance as I have just inherited
custodianship of our club's repeater. It is a Mastr Exec II operating in the
70cm band. It currently uses a NHRC-2 controller. I was asked to look into
the feasibility/cost of upgrading this system. Can someone tell me
I would recommend the SCOM 7330 controller. It is a three port controller
and is very nicely laid out card. You can hook up a IRLP as well a weather
station to it and all that.

I use a RLC 2a , RLC 3 and a RC 210 all good controllers and all will do
what you want ..
if its just for the repeater and a IRLP/Echo link node all you need is a 3

The Motorola 0185417U02 is equivalent to the Celwave PD5042-1-50 duplexer,
which is designed for a 5 MHz split. The Motorola 0185417U02 is NOT
equivalent to the Celwave PD5042-1-05, which is designed for a 500 kHz
split. The numbers you quote suggest that your duplexer was neither

---When it only transmits for a few microseconds when its first
keyed up, that is usually a good indicator either the alignment is
off or you have a failed part. Best thing you can do is see what the
test set tells you
Thank you Ken I will check that out. Dick W7RGW was the one how aligned it for
me so I will have his check it out.

I have a UHF RCA 500 series commercial repeater that was retuned and crystalled
for amateur 440 use. It was used as our first 440 repeater and to my knowledge
still works, but it has been off the air in storage for about 2 years.
It has a transmit exciter, PA, and receiver. Photos are online
Does anyone have a spare Motorola IC, either a MC1466L or a MC1566L, for an old
Lambda power supply? Thanks, Marvin

Eric--
The reason that the duplexer you received in your station had an isolation of
100 dB was that the tuning was done using a network analyzer by a qualified
technician. That is typical for these duplexers using a network analyzer.
I seriously doubt that anywhere near those numbers are
