Sadly no im not. My parents got it for me for Christmas this past year off

Hi All
We have been using Chip Angles Pre amps for years. Our system has 20-30 in use
on Mountains throughout NM, AZ and CA. They work great in high intermod areas.
we use a pass cavity in front of the Pre amp to narrow the crude that a good
duplexer still leaves. The extra cavity also

and look at

only need to send in the display and a note with the radio serial number and
return address. Suggest you join that group and ask the question again. I

the excessive gain is desired (ie not on a mountain top). So a user

Tim,
An old rule of thumb is that you get as many lobes in the pattern as the
number of 1/4 wavelegths from the tower. This was reflected in the antenna
literature in the old PD cataloges. At 1/4 wave spacing you get one fat main
lobe away from the tower. At 1/2 wave spacing you get a

My PD catalog just lists a PD-220, no other designator. Says bandwidth is 9
MHz and true
omnidirectional gain in excess of 5 dB. They are supplied in three frequency
ranges across
136 - 174 MHz. To verify the frequency range you will have to sweep it.

AA Engineering made a board/circuit to do just what you describe. A
friend owned and used one and it worked just great. Somewhere I've
got the docs on it... but check with AA via their web site.
Hamtronics DTMF Decoder could be expanded to do the same function.

Hello All,
I am in need of a 110Watt VHF (136-174) Motorola Mitrek for
repeater useage. It would be nice to get a power cord, mounting tray
and Tone board with the radio but the RF deck itself will do. Let me
know what you have and what you want for it. Thanks.
Can anyone tell me the difference between the 102 spec analyzer
option and the 01 or 02 (forget which is the SA) spec analyzer
option? It seems the units I see on Ebay always have the 3-digit
option analyzer, but some older brochures I have here show the 2-
digit option anaylzer.

Does anyone know where a CRT for an IFR 1000 or 1100 service monitor can be
scrounged up?
Thanks, Eric
What is the exact part number of the CRT you seek?

The spectrum analyzer was changed from option 002 to option 102 when

Go to your local Home Depot or Lowes and buy a 100 foot roll of #12-2 or 12-3
copper wire. #12 wire has a resistance of .159 Ohms per 100 feet so if you
hook the Black and White conductors together on one end and then put your power
supply on the other end you will have a high powered resistor
