I recently obtained a TEKK KS-960 Transceiver for 70 cm 9600 baud packet. I
need to change the crystals so that it will operate on a different
frequency. It doesn't look like TEKK is still making these radios.

Even though the radio came with the service manual, I do not see any specs
on the crystals.

Does anyone know the type of crystals involved for the TEKK KS-960 radio and
how I can calculate the frequency for the XMIT and RCVE crystals?

Around here folks are using 433.100+. I do not know why there are using a
split frequency. You can have different XMIT and RCVE frequencies in the
KS-960 but it is not designed for full duplex.

International Crystal should be able to make the crystals for you.

Likely using split frequencies for a digital repeater. We have 4 of
them in the Pacfic Northwest, 3 operational on UHF, the one on VHF we
lost the repeater council coordination so it is sitting idle.

Our repeater council expires corrdinations after 5 years, repeater on
the air or not if not renewed for a fee.

Thanks Gary. I will contact JAN crystals and see if they know the type of
crystals and
frequency needed for the TEKK KS-960 transceiver.

Yes, I suspect 433.100+ Mhz is for some sort of repeater. But I don't know
whether it is still
around. I am still trying to find out whether there is any 70 cm packet
activity left here
in Ottawa, Canada.

Since I have two of these TEKK radios. (I got two for the price of one). I
may be the only one on 9600 baud packet. hi

If my suspicion is correct and there is no digital repeater on 433.100+ Mhz,
I am probably better off getting crystals for simplex operation.

Do you know what are the more popular frequencies on 70 cm for simplex 9600
baud packet?

No I am sorry I don't know of popular simplex 9600 frequencies. All of
my 9600 operation is through a digital repeater here. Make sure you
set the deviation for no more that 3 KHz.
