Hi
I'm looking for a circuit which removes dtmf tones and maybe other
tonebursts from the rx audio before it is fed to the tx.
There are circuits around which use the MN3008 and MN3101 ics which
are both obsolete now so are no choice. One possibility would be to
replace them with similar ics

The arcom rad wil only help completely dtmf when connected to the rc210
controller the rad is just a delay. The dtmf decoders are on the controller
board.

Most DTMF decoder chips have an output that transitions when a valid tone pair
is decoded. This output can be used to mute the transmit audio while the DTMF
tones are present, snf most repeater controllers have the option of muting the
DTMF control codes.
In the case of a single tone, the

Thanks for the responses. I new about DB making the U/V version but not about
the U/U or V/V version. I think I'll opt. for converting mine to U/U and
sacrifice a little gain, but maybe improve some of the lcoal coverage with
better tilt down characteristics from
The only way to use the lower harness and still salvage/save for later is to
put a dummy load on the connector where the top half of the antenna
connected. Kind of ruins the efficiency.

Chuck thanks again. I thought that would be the case. I'll try putting the
splice in the lower section as you suggested and saving the the bottom TEE
(with the orignal pigtail) for returning to the original configuration if
needed, Just more tape and water proofing required to reinstall.

Yep, you could add another connector to the cut-off parts and re-connect
later if needed.

I can't see ruining the bottom half of a good harness when I
have top top half from another antenna that is been damaged
that I can use. Last time I had to replace one of the
connectors on a DB antenna the VB material in the cable
either was still sticky or got that way from trying to
Thanks Jeff, hadn't thought about the TCE (Trichloroethylene I think). I'll
check HD next time i'm there.
