Good afternoon
I am looking for the users manual/service manual for
the Zetron 45B interconnect . Anyone have one they wish to sell or lead me
to a source to get one. I inherited a site that has one but no documentation
was found with it

With regard to the Intermittent Duty 50 watt Stations, what is the lowest

I have a Mastr2 VHF station we're looking at placing in our command trailer

it draw as little
AJ,
You asked what is the lowest power level for the Mastr2 radio. I had taken a
250 Watt base and turned it down to 10 Watts out for testing purposes with
out generating any spurs.
However, If I remember to documents say to not run the poweer any lower than
50% of rated power out.
Remember,
I had the same thing when they installed their antennas immediately
adjacent to one of our 460 MHz repeaters. Swapping the TX/RX solved the
problem. I suspect that one was transmitter related.

Any idea what your current draw was when you had it tuned down to 10 watts?
I've been doing the alignment directly off of the exciter (250 mw off of the
RCA jack on the drawer) but the power output doesn't match the needs of the
mobile usage.
Thanks!

hi all,
I have a Phelps Dodge RFS/Celwave) 522-509 old UHF 6 cavity duplexer.
Each cavity has one tuning rod only.
Does anyone know what type of duplexer, bpbr, bp, br, etc this critter
is. I am trying to tune.

I'm looking for an Icom IC-22U for use at a repeater site as a remote
base. Physical condition is not particularly important. I would
prefer a working unit, but may consider one in repairable condition,
depending on the fault.

If I remember right, it's four notches and two passes. The normal
configuration was one pass and one notch on the Rx leg, and two pass and two
notch on the Tx leg.

To meet the new emission masks, the deviation on most older
transmitters would have to be below 2 kHz. And a hi-stab oscillator
installed.
And then it STILL wouldn't be type certificated for narrowband
operation.

That's not exactly true. TIA-603-C clearly states that there are two
reverse-burst formats, 120 (AKA 240) and 180 degrees, and gives neither one

shift stopped the mechanical reeds quicker than a 180-degree shift. Now

I would hardly consider moving from conventional analog to digital an
upgrade.
How about the shaft from a bicycle flag? Also, I've seen driveway
reflectors at Lowes that have fiberglass shafts for about $2.
If it were me, I'd put a Megger on them to make sure they don't conduct.
You never know if they might have some carbon fiber added for strength.

I readily agree that it IS possible, but darned if the commercial
manufacturers are not using that DSP capability to discriminate between 120
degrees and 180 degrees of reverse-burst tone shift.

a Motorola repeater- on

Yes, the factory standard antenna is fairly narrow beast.
With a little bit of magic, mirrors and a modification I
can get one to perform good enough for my 43 to 53 MHz needs.
