Because most 'rice rigs' don't have high pass filtering on the
mic and false tones 'all over the board'. I know - I've tried it.

I'm not sure why you think "tone panels" are not a good fit for a ham
repeater?
The Zetron Model 48B I'm using has CWID that can be adjusted in
increments of one minute intervals.
I haven't seen very many commercial tone panels that didn't have
built-in CWID.
Most do have remote programming over
First thing to come to my mind is you are using a power supply with some
inductive filtering. You may have a spike coming in on the 12v line or your
radio may be critically adjusted on the VCO side. Is there any error codes
displayed in the display when this reboot occurs?

DCFluX,
That worked!
I lifted one side of R188 instead of going to the IC.
CWID, courtesy beep and status tones are back and no more squelch
tails with delayed audio.
I'm not using the telephone patch anyway but Zetron did offer an audio
delay for that feature.

The preamp had better amplify all things equally! If it doesn't then it is
non linear and you have an intermod generator connected to your receiver.
But if the preamp is driven hard enough by a strong signal(s) to drive it
into compression then it becomes non linear. A condition that you want to

Absolutely GOOD ADVICE -- so that you wil inimize problems once your repeater
is installed.
I would select a nearby Kenwood dealer and ask them to align/setup the repeater

the actual caviities that you are going to use (actual antenna also -- IF you
have it)

Dave,
Yes, you must adjust at least the five front-end coils, but it is best that
you have a service manual in front of you when performing a significant band
change on a TKR-750 repeater. Both the front end of the TX-RX board and the
VCOs should be adjusted for optimum performance. An accurate
Jeff,
The M1225 mike jack is numbered 1 to 8, from right to left, as you are
looking into the jack. The functions are as follows:
1 +8 VDC
2 Not used
3 Hookswitch
4 Ground
5 Mike TX audio
6 PTT
7 SCI Data for programming
8 Handset RX audio

When you are plugging an RJ45 connector into the MIC jack, the tab will either
be on the right or on the bottom. If it's on the right, the uppermost pin is
#1. If the tab is on the bottom, the rightmost pin is #1. If the MIC jack is
oriented some other way, make the appropriate adjustments. Note
I have one from a Spectrum repeater power supply..25.00, shipping included.

Hope this is the correct group for this kind of question. I'm trying

Anyone know of a supplier for power supply transformers? I am looking

HI ,I am New,
I have a TKR-750 that was on 159.xx mhz.
I moved it to 147.xx mhz.
The transmit works great.
What do I have to adjust on the rcv side.
I understand 5 coils have to be tweeked.
please explain.

That's because Zetron makes commercial tone panels, not repeater
controllers. They don't use delay lines for the purpose of eliminating
squelch tails and DTMF muting.

Looks like there is a delay plug in there, but it is only for the

I'd recommend you remove the 4066 that is located at U35 and lift up
pin 4, Stick a wire in the socket and solder a wire to pin 4. The wire
going into the socket will be your RAD input and the wire
Oh, ok. I will dispose of it then. I have no use for it.

Depends on whose camp your in...
A lot of the above thinking is probably related to much
earlier semiconductor performance versus what is now
available for the same application.

Hi,
I got a preselector from a vhf johnson repeater. It has 9 slugs in it and 4 RCA

Does it have a built in preamp or is that a mixer? Part number is TLE8023APR.

I bet you were right at a null directly under the antenna. 15 feet is just
sort of 2 wavelengths.

Ken,
That won't work either.
I can't gate the receive audio since discriminator audio is fed to the
panel to determine valid PL tone.
I simply need to find a location inside the panel to break transmitted
audio ahead of the CWID and status tone generation section.
