Well, the DB224's are common antennas, and there seems to be a lot of talk
about them. Thought a seperate folder would be nice for them. That's the only
good reason I can think of! Thanks!

That's because Joe halted the development. He pleaded with potential users
to interface it with their choice of radio. I was the test for the Delta-S
low band. There were several other volunteers who did other radios. As each
one was proven to work, Joe added the programming for that particular
Steering the PLL in the synthesizer is not the only thing you need to
do. PL/DPL encoding and decoding is all done in software. Unless
you want to add another encoder like Joe did you can't take that
approach.

If you are considering purchasing the Hamtronics REP-200

Kenwood is a much better built piece of equipment and has
a decent built-in

No. Narrowbanding only affects Part 90, and Marine is
Perhaps someone out there in RB-land has an old copy of a schematic
for a yaesu NC-2 standup desk charger. These were used for the FT-207
and FT-208 handi-talkies back in the day.
I did google it - no results.
Thanks for any help

Marine is not part 90 (I think it is part 22??). It should NOT be affected.

It should also be noted that VHF Part 80 cannot be narrowbanded
without an International agreement. That means it's not likely to
happen for quite a while yet.
Much like switching aeronautics

Skipp,
I agree with nearly every point you made, having had experience with both
the Kenwood and Hamtronics repeaters. However, Hamtronics and similar
repeaters have one serious deficiency: A total lack of PA protection against
high SWR due to antenna or feedline problems. In addition, the
Hi guys .I was looking at adapting a midian tds-1 to a maxon pm150 but we

Can anyone suggest ideas to give rf protection to the decoder chip .I came

And to install the chip in a metal case
I have a TRN5074 PL board that I cannot find information on. I know it is a
simplex board. If this is installed in a repeater is it used on the RX side or
the TX side?
Also, does anyone know of an economical way to convert microfiche to PDF or
printed form? I have a manual on microfiche but
Hello Ian
IF your repeater is a UHF and the CTCSS decoder has a 5 MHz crystal oscillator,
it will mix with the transmitter and give a signal at the receiver frequency 5
MHz lower (in Australia RX 433-435 TX 438-440 MHz)
This a is a common occurrence with UHF Philips FM-828's.
The fix is to use
Jim, I see the TRN5074A shown in the MSR-2000 Base and Repeater Control and
Audio manual, Motorola Manual Part # 68P81061E40-O. In my manual, the part
number of the sub-section in that CA manual which covers the Tone
Private-Line Encoder-Decoder Modules, models TRN5073A, TRN5074A and TRN5075A
Yep uhf 450-470mhz.I will check on that and make sure

The complete information on the TRN5074 Tone encode/decode board, along with
all other MSR2000 accessories, is contained in the MSR2000 Control and Audio
Manual 6881061E40. This large book is still available from Motorola Parts
for about $60, and is worth every penny. Call 800-422-4210 to

Hello again Ian
I've also tried a decoder with a 4 MHz crystal and it still heterodyned.
Get a tunable decoder and your troubles will be solved.
What I found was if I turned up the TX CTCSS encode, the decoder activated and
held up the receiver which held up the transmitter etc.
We also had a ~
