I even read about a guy using an old Heath HW-101 for PSK31, after warmup of course. The Ten Tec PTO can be made more stable by tinkering with the temperature compensating cap. They were all individu
Well, you could crystal them up for a net frequency, but amateur nets seldom stay exactly on the published frequency. The NTS nets often have to QSY to dodge QRM. You could crystal them up for the 60
It was probably sold for MARS, CAP and commercial use, probably exported to developing nations, too, where they don't have a fully developed telephone infrastructure, so they depend on HF more. It pr

John: Didn't one of the after market program chips, like the Giehl chip have some sort of "transmit indicator" on the display. Look inside and see if you have the original Ten Tec chip. If there is a
Follow up: If you have a PLL problem you will either hear all CW signals warbly or unstable. This instability is caused by poor solder joints on the PLL boards. If the PLL is actually not locking, yo
John: Ten Tec uses electret mikes with built-in preamps, so they require d.c. voltage. A dynamic or ceramic mike with no internal preamp does not need the voltage source. 73, Bob WB2VUF thanks again,
Make sure your RF PWR control is set fully clockwise, then set the Mic gain control to make the ALC LED flash on voice peaks. Note that because of the duty cycle of SSB and the time constant of the m

No HF, even as backup? Ancient history now, but I was in Tel Aviv on business in 1993 and all the embassies I saw had HF antennas on the rooftops. Interestingly, most were dipoles fed with 600 ohm op
John: How do you feed the dipole? I have a Drake MN-7 (cosmetically almost a perfect match to my Corsair). It loads the my 80m coax-fed dipole on 160m, but not perfectly. I'm thinking of switching to
John: I don't know about the "manipulate" function, since this would imply a program that would control the O II, but I have found SW management software that looks intriguing. I haven't tried it mys
Thanks, Bob Yes, my coax-fed 80m dipole only works on 80m and its odd harmonics. That's why I'm planning to switch to balanced feed. After reading the material on W2DU, Walt Maxwell' site, I'm going
Well, the embassies that I saw were all in an urban area at the shores of the Med. There was no room for big antenna arrays. The HF antennas had to fit completely on the embassy rooftops, hence most
30 51J4's must have been a sight to behold! Probably got hot in that room, too. I have a picture of a navy station in Antarctica that had a bank of R390's. In 1998 when I was in Switzerland, I saw a
