Does anyone know anything about the roger bleep unit in these radios? I used
to know, but its been 20yrs since I keyed up last. Are they already fitted,
and need to be activated on the board? any input would be appreciated...
thanks

There were about a dozen different models of radio branded "ham
international".
They used "cybernet export" circuit boards. The PTBM121D4X board, often
called a Hygain 5 board had space on the circuit board for the usuall
bleep circuit
with an oscillator using a transistor and three r+c sections for the
feedback plus
a couple of switching transistors and related parts.

My memory is also a bit vague and my file of CB circuits and notes is
deeply buried.
I think all the cybernet export boards has space for roger beep
components which
were not allways fitted but I might be wrong.

Here is a nice website with scan of the circuit diagrams of a couple of
cybernet export boards. They don't show the roger beep circuit
unfortunely.

Multimode II's/Concorde II's and Jumbo's had a Roger Beep built in to them
as standard. It was a small brown rectangular pcb with a thickfilm circuit
and a single 4011 integrated circuit, PCB number is 715226 and thickfilm
number 715904. But most of them have been butchered over time and most that
I have seen recently have had them removed completely.

I can't understand why they weren't simply by-passed. A future buyer might
have wanted the bleep and it would have been much simpler. Oh well.

I beg to differ. I owned both a Jumbo and a Multimode II both with the
PTBM059COX main board and PT0S006A0X crystal/vco board, and in both cases
they had factory fit Roger Beeps.
