And how does it compare to "vintage" gear, like my Paragon? Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/li
Howard: L1 is used to adjust the frequency of the 9.00 MHz crystal. T1 is a 455 kHz tuned circuit. You can probably make a new one from an old 455 kHz IF transformer. Q1 and Q2 are type MPS-3693. I'm
I like that idea! Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec

Curt: Most Ten Tec owners seem to be going to Poco Sales (http://www.pocosales.com/). They have a minimum order of $25. The breaker that you have looks like the Ten Tec 1140, which was used for the C
Dave: Did you try rewiring the mic element so that it is powered all the time? Maybe the mic power is going through the PTT switch and the turn-on transient is putting out an audio pulse. 73, Bob WB2
Dave: Well, the only other thing that can suggest is an RC circuit on the power input to the mic to slow down the rise time. 73, Bob WB2VUF _______________________________________________ TenTec mail
Good, job, Dave! It's always a joy to fix or improve something. 73, Bob WB2VUF _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/ma
Alan: I have a 1254 and really like it. It is sensitive and stable. The steel case makes it rugged and professional looking. It has a balanced JFET mixer in the front end and an AGC-driven automatic
Alan: Merry Christmas! Thank you for the links. I was aware of the mods on Marshall Emm's (mtechnologies) web site, but the replacement processor mod is really exciting. It would bring the receiver c
Alan: No, I don't have any processor problems. I was referring to the mod kit available here: http://www.cholakian.com/TT1254upgrade.html, although I don't find the coarse tuning steps of the 1254 th
Thanks, Dr. Gerry, That's interesting info. My Scout is spec'd at 600 mA on receive. I typically run it at 30W and have had excellent results using a low (NVIS) portable reel-out dipole made of AN/CR
I forgot to mention that there are video demos of some of the Ten-Tec kit receivers on youtube, including a demo of the 1254 by Scott Robbins on Ten-Tec TV. Bob WB2VUF _______________________________

We called it "short skip", during my misspent youth. From my Novice days in 1966 to the present, I don't think I've ever had an antenna higher than about 25 feet anyway. I work mostly 80 m traffic ne
Wow! John Brune and his sidekick John Gratalo are the guys that I ran into at Lakehurst NAEC in 1981 where they were flight testing the system. I didn't know that they were famous. When their project
The BFO/carrier oscillator crystals may have aged and the 15.3 MHz oscillator (L4) which centers the passband tuning may need adjustment. This you can do by ear, but the BFO frequencies require the u
Yes, QST in around 1967 featured the "mobiloop", which was similar. I can't imagine driving around with one of those on the car today. Bob WB2VUF _______________________________________________ TenTe
Well, what prompted this discussion was the fact that I zapped the finals in my Century 22. It was a series of errors. I had left the drive set to full power; band was set to 10 MHz, but autotuner wa
Jerry: Thanks. I have the original breaker that Ten-Tec used on the Corsair and it translates to an Airpax "instant trip", which are scarce. The fast trip appears to be an acceptable substitute, thou
