Re: HELP WITH SWITCHING POWER SUPPLY

Jack Jackson
 

Hi Mike,

Have used Duracom and Astron switching supplies on VHF & UHF repeaters and
paging systems for about 6 years with NO problems. They run much cooler and
do a great job. You will not have any noise problems unless you use the
supply on an HF rig!

Subject: [Repeater-builder] HELP WITH SWITCHING POWER SUPPLY


From: HQ54@...



Hi All,

I recently purchased a Switching power supply. It was rated at
considerably more amperage then most of the REGULAR power supplies I had
seen, and was more affordable, so I had to buy it. I have since learnt
that
switchers often cause some sort of interference, especially at the VHF
frequency range. I have also heard that there is a way to either elimate
or
considerably reduce this interference. Does anyone out there know how to
accomplish this, or know where I might be able to get that info. I have
yet
to attempt to use the unit, but I would like to be prepared incase I need
to
do something.

Thanx in advance for the help
Mike

Repeater Antennas

Hi Guys: I am working on putting a repeater together with a few other
folks help, and I am in need of a reccomendation of a good UHF repeater
antenna. I have seen a few of the DB products antennas and called them
about an antenna that would work for amateur UHF purposes. They
informed me that they do not build an antenna for the Amateur UHF
frequencies. I would like to stay away from the fiberglass antennas
also. The local repeater here used one for a while but the noise
buildup sometimes made the repeater almost useless to use. The
frequency for this new repeater is on 442.700 Mhz. Any help you folks
could reccomend would be appreciated.

Hey there!
Many well thought out reply posts to my query "what to
coat Aluminum (metal) antennas with".
Condensing the solutions offered:
1.) (solvent-thinned) rubberized "tool coating"
2.) Liquid RTV (solvent-thinned RTV)
3.) auto body "chip guard" plastic coating
4.) maybe stainless steel antennae?
5.) epoxy (aircraft) paint
6.) exterior acrylic (clear)
7.) Sherwin-Williams polyurethane enamel (per Celwave)
Now, those all look viable; Now I have to calculate which
one(s) will
cost me the least $$ and be the easiest to apply. I think I
can handle this part of the equation <g>.

Thanks to all who participated!!

The decibel products folded dipole antennas cut for the 450 to 470 MHz
range work just perfectly in the 440-450 ham band. My repeater is living
proof. Others in my area are using the same thing. They are fairly broad
banded, and they work fine. I replaced my so-called diamond X500 HNA
antenna with "11 dB" of gain with a DB products antenna with 6 dB gain and
i actually gained a field strength of 3 dB. Go figure, i guess.

squelch crash. :) From what I recall, the RLC-SQL was (is) more than
that and only reduces the crash on strong signals.
Thats what I have in my bookimarks. It puts you directly on their catalog

We use the RLC audio delay boards. The audio delay boards doesn't address
the problem of weak and fluttery signals.
So far we use the audio delay boards here in Calgary. We use them on our
RLC-2A. We also use a few RLC-4s

Re: Canadian Marconi "MARCOM V" Programming

Ken Whalen <[email protected]
 

Fred,
This is the codes you requested for the Canadian Marconi Marcom 5 VHF
Mobile. ETS/CTCSS requires an add on board that plugs into the 28 pin
header located just behind the head. Two types of ETS boards are
available, a single tone and a multi-tone board. The Multi-Tone board is
controlled by the 1/10 buttons next to the mike jack.

Hope this helps.

That should work well on a antenna.
