Hello Group,
We are looking for simple EM to Ethernet Interfaces. Single or Dual channels
would be great as we have an application where we would prefer not to install a
complete MUX assembly where something that would provide us with 4 Wire Type1
EM to Ethernet would be ideal.

HI All,
After 15 years of faithful service our Diamond X510 dual-band RX antenna has
failed.
We started getting some noise and poor signal input to the 2mtr repeater. We
had decided to check the 2x X510 antennas (1x TX and 1x RX).
A couple of weeks ago the TX was checked and found to still be
Go with the shorter antenna, but if you need/want the higher gain and your
antenna is side-mounted to a tower, consider adding an anti-sway support near
the top of the antenna. I've got one on my 20+ foot UHF Super Station Master
antenna. It was pricey ($250US) and I don't think it was

Frank,
I don't think you'll find a specific instruction for these models and not
sure exactly your starting point so first set up cables like this.

its best to terminate all 3 ports of the duplexer with 3 or 6 db pads
Attach 2 cables to 'Duplex Out' and 'Antenna In'
Attach the ends of the cables to the duplexer, Duplex out to 'Antenna'
and Antenna In either side. Terminate the opposite side of the
duplexer with a 50 ohm dummy load.
Select the Spec Analyzer.
Set center range to the first desired tuning

Hello all
I am assembling a Mastr II UHF station into a repeater and have acquired a
real FM exciter
and crystal for it.
I'm having trouble deciding from documents if I should feed it flat or
de-emphasized audio?
My best guess is that GE designed this so the FM exciter takes the same Mic
Ian,
The Motorola catalog lists M1106 and M1107 transistors as special and
without any technical specifications.
It probably won't change your desire to find out what their specs are, but
you can still buy them from Motorola Parts- at very high prices:
M1106 is Part Number 4884411L06, $ 133.88
Hi all,
I have aquired a EMR Isolator, model 7450/4 for 150-170 Mhz and tuned
to 155 MHz.
It has 3 tuning adjustments so need to retune it.
Can anyone give info as to how to tune it or where I can get info. EMR
has good info on what it does and how it works, but found nothing at
their site

Ron,
Contact EMR and request a copy of the bulletin, Field Tuning of Isolators.
Be aware that typical circulators and isolators can be field-tuned perhaps
+/- 2% from the frequency for which they were made. If you want to use it
at a new frequency that is more than 3 or 4 MHz away, it probably

Ron,
A simple but effective method of tuning a single junction isolator (3 tuning
ports) can be done by using a few basic steps.
First tune the input and output trimmers (usually found on the lower part of
the isolator opposite the attached dummy load) for maximum power through the
devise. To
