Default Re: Common Pye PF1 RX deafness problem

Our chief tech trusted the main workshop's Schomandel so much he allegedly once rang Droitwich to tell them their 200kc/s transmitter was off frequency...!

I have a pair of PF1s on the shelf here as a reminder of my roots... My son, who is an Airwave user, was fascinated with them. When you think about the technology used to get a voice from A to B now, and then...

As a young WM and WT I remember netting PF1 transmitters against the Racal calibrator. I guess we must have netted the SG1 sig gen too after it's xtal was changed and before it was used on a new freq along with the 10.7MHz marker osc, but I don't remember actually doing that! The SG1 was left on keep it warm and minimise drift. In this area PF1s were used with Pye F450 and F460 base stations and Pye RTC 'Teak Box' and Mascot 50 controllers (with a tulip mic wedged into the operator's console and a footswitch for PTT).
