Hello Morris,
My schematic for the SCR-200 dated 5-17-82 shows Q101 as an MRF901
transistor. My schematic dated 7-22-86 shows it as a 6033.

If anybody has a Sinclair Q202GR-1 model duplexer or a TX/RX 28-37-02A model
duplexer. I am in the process of rebuilding the club repeater system and
need to replace the old duplexer that is older than dirt. If you have such a
unit that will work would you please contact me OFF THE LIST to cut
Haven't been following this thread that closely, but if Mobile to repeater
coverage in your downtown core area is good but HT coverage is marginal, (and
coverage everywhere else is acceptable) why not 1. try a preamp on your
repeater receiver or 2. consider changing out the cabling from

It is the same as Orion It also depends on exactly what cables
and/or connector you are pulling from... External PTT and COR need to
be mapped in software to external I/O pins.. not all appear on each
cable One downside, as of most recent info I have, there is no
constant audio
Hi Joe,
That's a big help. I saw what appeared to be 106 printed on the transistor
but the schematic said 6033. With the information you provided it must be a
MRF901. All I had to do was stand on my head and read it correctly. It
appears that you have the solution to my problem and I am
I'm going to suggest another Poor man's voter
despite the probability that someone, somewhere,
has already done so.
I was thinking you might go ahead build your
2nd rcv site with a one way link to the main tx.
However, you would rely on the link activation
to vote the rx signal into the
That's what this list is all about. I'm glad you found the answer to
your question.
Now it's my turn, I will be posting a question about MASTRII PA amps.

Hello list dwellers,
I went to our repeater site today and found the MASTRII PA dead. I
could hear the exciter on my HT and the exciter output checked out OK at
250mw. There was good DC to the PA deck, but no current draw. I
checked the usual suspects, the 2 buss wires that carry the DC,

I believe that you now have a nice Haliburton aluminum briefcase.
Perhaps a DC power supply.
The duplexer might be usable as some sort of filter for reception in the
high VHF range
Unless you are licensed for something in the high section of VHF the rest is
just a
Joe,
Use a magnifying glass to closely check every solder joint for cracks. Some
such cracks appear due to temperature cycling over time. I have already had
the same problem, where a PA was dead at the site but worked fine on the
bench. It was around 40 degrees at the site, but around 70 at
I need two mounting plates for the trunk mounted transceiver.
Also looking for a low power Mitrek to be used as a receiver on 147 MHz.

Hey gang I am tired of scratching and clawing for 1 Rack Unit 19
enclosures for controllers.
Does anyone have a source for these at a reasonable price?
Thanks Tim
Oddly enough, the last 3 I've used for repeater controller came from Power
Strip/Surge Suppressor surplus auctions off of eBay... Once I removed all of
the AC outlets and covered the unneeded holes with flat aluminum stock from
the Home Depot, it gave me plenty of room to mount the controller
Tim,
Scratch and claw no longer. Marlin P. Jones has just what you want, for 20
bucks each. I just bought two of them. Go here:

A 30 second DTMF blast? I think I'd use the first several
milliseconds of that to switch the radio to a useful channel.

If the digital is on a very different frequency, then the frequency
change is a reason why digital reception may be problematic. For
example, if you are using a VHF antenna to try to receive
a UHF digital signal, that will be problematic.
