It's not repeating from one 2M freq to another that I know
The SSM antennas have a very narrow angle of
radiation, hence all that gain. Close-in performance,
or stations under the umbrella, don't do too well. I'm
using a PD455 cut for 440-450 on my repeater on
444.xxx and at my end of the 500ft of coax there's 55
watts forward and about 0.3 watts
Re: Spectrum Communications SCR 77 UHF repeater
You might have asked for a few more opinions before you bought
a specific controller. Replacing the internal controller is
quite a bit more involved versus dealing with just the CW ID'er
function using something like an ID-O-Matic unit.
Do you
Found the problem on the squelch board, squelch tail timer. Fixed and
trhen another problem with duplexer. Now on 2 antennas until I get the
duplexer tuned.
Good Afternoon,
While going thru my Micor stuff, I found that one of my station power
supplies (TRN1011?) suffers from voltage sag under load. I know that
by design the power supply voltage should drop under load. Most will
idle around 15v, then drop to about 13v under load of a 100w PA.
If it's the TPN1110 supply, the PA supply is very
simple. A ferro-resonant transformer, two diodes, and
LOTS of capacitors. The transistors are for the
low-current regulated supply.
One diode could be open. If so, I'd expect a lot of
ripple on the supply and low voltage. If one cap was
bad, I
Eric,
I ran some load tests on a number of Motorola, GE, Astron, and Samlex power
supplies, including the TPN1110. When connected to a suitably stiff 120
VAC power source, the TPN1110 is specified to deliver a quasi-regulated
output for the PA of 13.8 VDC at 25 amperes. I use the term

Hi All,
I recently acquired some AWA RF modules:
2483 VHF RX
2738 Interface
2506 VHF TX
Any ideas where I might be able to get manuals / drawings for any of
these ?
Many thanks,
Mark.
Yes skip on the back there is a 12 pin accessory jack with the following:
pin 1..Aux AF input
2..RX AF output
3...Aux COR switch(goes low, 0.1 V with incoming signal). (open
collector.) 100 mA max
4..Aux PTT input (GND = Transmit) Will not time out
Mark,
Since AWA equipment was manufactured by an Australian firm (Amalgamated
Wireless Australasia), you might try contacting any one of many Amateur
Radio clubs in that country, that use AWA equipment. I used Google to
search for Amalgamated Wireless and came up with dozens of sites that look
Has anybody had any luck at programming the tk690 into the 6 meter
band and useing 1 for trans and 1 for rec to make a repeater???
Thanks Freddy

Yes you can. The DB25 connectors will give you everything you want on the
pinout.

I called RFS this afternoon. Sad times, indeed. First of all no one
there could identify the connector/adapter part. Second of all, they
claim no spare parts available for Stationmaster antennas. I even
tried to buy a set of radials for a PD455 that has lost them, and
they don't even offer
Hi Bob,
The PA is ok, as it is working fine with other Micor power supplies.
Or should I say, the current draw is within spec. This supply was
tested in two different Micor systems with the same results.
I will dive into it this weekend.

Donno about UHF radials but I've fabricated my own for the VHF Stationmasters.
If you
are unable to locate the desired fitting you may be able to use a UHF double
female
barrel adaptor on the UHF male at the antenna and then use a UG-83 adaptor
(which is
a UHF male to type N female). I
Try googling Exicom in New Zealand. This was the crowd that took over
production of the AWA repeaters as my memory serves me correctly.

I tested the antenna using two adapters to get from the UHF male of
the antenna itself to an N female. But likewise, I don't like using
adapters, especially high up on a tower where it's not easy to get to.
The part is labeled (stamped) as follows:
