PCF-2 WITHDRAWN

             Ray and Woody have made tests on the prototype
version of the PCF-2 and have found some problems. The decision
has been to discontinue distribution of the PCF-2 and return to
the PCF-l. Ray
expects to have a revised version of the PCF-I available shortly.

PROGRAMMABLE KEYERS'?'?

             Does anyone have a AUTEK Programmable CMOS Keyer? It
is advertised for $100 and I was
wondering if it could be converted to CCW. I wrote the company
but they refuse to send me a circuit
diagram or discuss possible modifications. If someone has one,
would you send me a copy of the diagram so l can examine the
possibility of its use in CCW. Woody

A CCW RECEIVER?

             Ray Petit has on the drawing boards a
high-performance synthesized receiver designed for CCW.
He is considering the possibility of making such a receiver
available in module form. A key question is
the market for such a piece of equipment. If you are interested,
write Ray a note. The degree of interest expressed will be a
factor in his decision as to whether to proceed with the project
or not.

DIOLN on CCW

             Rein Couperusz DJOLN, PAORCT reports he has his CCW
rig on the air. His transmitter is a HW8
with a I kHz spacing 100 channel synthesizer. His frequency
calibrator is a temperature compensated
100 kHz Xtal checked against Droitwich at 200 kHz. His coherent
keyer consists of a SN7474 operated
by a hand key. He is using a simplified version of the Petit
filter, with only one integrator and four
oD-amDS .

             So far operation has been all on 80 meters. Rein
keeps a regular sked with PAOAGA and PAORDT
who are also interested in CCW.
