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
Let me know if you find that storeroom full of radios. I have dreams about it! Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contes
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 _____________
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
Also shoot some contact cleaner into the AGC toggle switch. 73, Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailma
I did that with my Scout: put a 56 ohm resistor in series with the lamp. Reduces glare when portable, mobile, or sleeping. 73, Bob WB2VUF _______________________________________________ TenTec mailin
Scott, I would look around the heterodyne crystal for 40 m or perhaps the crystal itself is bad. 73, Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.c
Woody: Happy Easter! Does the problem happen on all bands? If only on one band, check the bandswitch and look for cold solder joints on the coils on the Bandpass Filter board, 80976 (not to be confus
Dennis: The Corsair is probably a better deal if you want to work the 18 MHz band. The Omni D will supposedly work on 18 MHz with the addition of the proper crystal, but the mixing scheme causes it t
Jim: Have you checked the Explorer Forum? (http://www.4x4central.com or http://explorerforum.com) Look in the ham radio subforum under the hobbies forum. Also Ford has a radio installation guide that
There is a place to access the fuel pump cable about 2 feet to the rear of the tank. The harness has a connector on the inside driver's side frame rail near the spare tire. You only have to drop the
Most people seem to get their Airpax breakers from Poco sales or one of the marine electronics suppliers. Poco has a $25 minimum order, so you may need to buy 3 breakers. 73, Bob WB2VUF _____________
Yes, there is a write-up in the ARRL Antenna Book on common zip cord. They found it to be very lossy. Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.
I can't confirm this but I read somewhere that blowing sand caused a static charge buildup on antennas which zapped receiver front ends. The rumored fix was to bring some R390 receivers out of mothba
Yes, the products my company builds usually have "transorbs" on the power inputs to take out EMP and line spikes. We also recommend shielded cables for power and signal. My Paragon has what looks lik
I'm sure that he meant 1974 or 1984. In 1874 they only had landline morse telegraph. Now during the civil war they sent up observers in balloons with morse keys. Lightning would be an issue there, bu
