Here is something else to try. This assumes that the PA pre-filter has
been tuned to your frequency. With the TX filter bypassed, but everything
else hooked up, try turning the power set control down a little. It may
be that you are simply driving the PA too hard and it is shutting down.

Sitting here looking at the tune up procedure for the filter, it tells me to insert a rf millivoltmeter probe into J18 and insert a 225 mV signal into the the output of the post filter. I did this, and get nothing on the meter at all. Now I'm not sure if there is a difference between my RS
Eric, Tnx for info; I will check them out.

Chas,
I suggest you look for a Motorola TLD1692 Power Amplifier, which is
rated at 100
watts continuous duty in the 132-150.8 MHz band. You'll also need a TLD5321
Exciter and a TFD6111 Bandpass Filter,
The built in duplex filtering option is simply a very high Q pass filter
system. Everything on the TX side should be tuned to your TX frequency.
The RX side of the filter is actually the receiver front end. which
should be tuned to your RX frequency. Since you have a single frequency
Ok, I do have a SA, so will use that. Ok, hence then, just like my duplexers on my 2 meter system, I'm thinking the prefilter is for the tx and the post filter is for the receive? So if I inject a signal into the input of the prefilter of 442.000 and the output to my SA, I should be able to
Yes, you should be able to get it to work by using an
SA as the detecting device in place of an RF
voltmeter. In fact, you could almost treat the filter
as a mini-duplexer and peak all the coils if your SA
also has a tracking generator. The only problem is
that the peaks are rather broad, whereas
Love that old copy of Commshop! It's still a great radio tool.

hi ,
humm i dont know if i am at the right place,,
anyone knowes this Motorola Power supply,TPN11108
it is based on a Micor Pager unit that i dismantle
at this moment it has a fix voltage at 15 vdc,to much for my master 2
i need 14 vdc
and i dont see any potentionmeter in the power supply board
Hi all,
When building repeaters many of us use older, but still very good
equipment such as Motorola and GE. The newer stuff that cost
thousands are what the commerical guys use, but repeaters made from
older units work great and can be had for much less.
This often means the need for
The normal GE supply is 15 volts without a load,so I would go ahead and
use it...

Hi Mike, did a little research and found one in Chicago. I knew about the SM, just never thought of one being outside the SM. So should have one here in a few days, and then get back to working on the repeater.Mathew Mike Morris [EMAIL PROTECTED] wrote: At 05:13 AM 11/13/05, you
Yes, here is a product called STUF. Look at:
http://www.wavehunter.com/
and look for informaton for Stuf Dielectric WaterProofing Filler
My company tried this product on an 800MHZ system with terrible results. Poor
return loss readings, loose connectors after time, were some of the problems.
The unit that I got is the Boontoon RF Millivoltmeter Model 92E. Looks like it should cover what I need it to do. Thanks for the help, when it gets here, I am certain I will have more questions until this repeater is up and fucntional, and then comes the fun of tying in an outbord controller
Anyone know a link to or have programming info for the 1P controller?
TIA,73,Lee

Boonton makes some nice instruments. Just make sure
the RF probe comes with it (they plug in and are often
not included), and that the unit is guaranteed to be
working. You don't need to measure the exact
amplitude, you only need to detect the peak and dips
as you tune the filter coils.

Not really. You might contact B and D Enterprises, but they no longer sell
the 1P.
