Hi
Thanks for the replies on this topic. I measured the dipole loop and
came up with 13 1/2 inches. The measurement was taken from one side of
the loop from the top of the loop to end just were just goes into the
mounting backet. I need the lower half of UHF at 423mhz for receive
only.

You lost me on that one.
Again, measure the element from tip to tip.
It will be 12-1/2 for 406-420 MHz
It will be 11-3/16 for 450-470 MHz
If your intent is for RX only, it won't make a lot of difference if it's out
of band, but you will loose some gain.

Anyone know where I could pick up an IFR FM/AM 500A service monitor
manual . . . just picked up one at a hamfest without the manual.
Tnx, John/N4SJW

Hey guys,
Alright, perhaps some of you have some ideas, cause this one has driven a
bunch of us absolutely crazy.
At one of my repeater sights, I have a 220 repeater, a 440, and a 900.
Also, there is a paging transmitter about 3 feet away from all of this.
Here's the issue. The paging

The Zetron Model 48B I'm using has CWID that can be adjusted in

I haven't seen very many commercial tone panels that didn't have
built-in CWID.
Most do have

You might use a spectrum analyzer first, to look at the paging system's
signal- it could be spurring. Note that harmonics of the 152.6 MHz carrier
will appear close to your repeater inputs, so you might try some bandpass
cavities on their inputs. Some VHF paging transmitters have more than

Acorn was in the news late last year for voter fraud, mostly for
fraudulent voter registrations. I didn't follow it too closely because
it pissed me off so much. They were being investigated but, now that
obama is in office, that appears to have been stopped, and the

Hi,
I have a RC-210 for sale that is in the Arcom rack enclosure with the
autopatch (AP1) module. It was built by me was in full operating
condition when I was doing burn-in on my repeater that I have scrapped. I
would like to get $400 OBO for it. Please email me off list if you are

I have a ULS preamp that has a bad transistor. The bad transistor on the UHS
preamp board is a GE Mobile Part Number 19A116818P1 device (marked 6818P1).
Would anyone have one that we could get?

Wow...another good one...I liked his antenna design...

I looked at the parts list for the UHS preamplifier in LBI-4561C, and saw:
Q2301 N-channel FET, similar to 3N187. You can buy this very common
transistor from Mouser or Digi-Key.
You can also purchase the exact GE part 19A116818P1 from New London
Technology, for $2 each.
The 4 can Wacom's can't do anything about out-of-band signals. You
might experiment with a nice high-Q filter on your receive side...
but...
Eric's right. To really figure it out you need:
1. To look at what's going on on a spectrum analyzer.
2. To move away from their antenna, vertically.

What is today's market for pagers? I can't imagine there's any real reason
for them to continue to exist. If the FCC can force you to quit using your
perfectly good 25 khz rig, force the multi-billion-dollar-a-year OTA TV
industry onto HD, or the zillion other examples of the FCC's
Question for any electrical engineers out there.
Are the meters on the side of buildings metering real power or apparent power?
Is power factor correction worth doing if the power company is not dinging the
customer for low power factor?
