The connectors consist of standard Molex parts. A few months ago, I bought an assortment of shells and pins to go with the various radios I own, including Ten Tec. I don't remember which vendor -- it

The Ten Tec amps are designed so that you can loop your transceiver through them to get to the antenna. If you have the amp in the standby mode, it isn't active, but the power supply is on and all it

I bought a used 746 from a local ham who had loaded it with filters. I'm VERY happy with the 746 on 6 meters, but don't use it on the low bands because I have other radios that are better. I tried to

Look at SurgeX (www.surgex.com). Their series mode surge suppression has become the favored method of many of us working in pro audio. Not cheap, but neither is the gear being protected! Jim Brown K9

I am using the T-line to key my Hercules (original) from my Omni V, because it is specifcally designed to be keyed by the T-line of the original Omni-series rigs. It's a very simple mod to go inside

The transceiver doesn't have to be designed to be keyed by an amp, it only has to be capable of being keyed by a straight key. The amp keys the transceiver's key jack (as if it were a straight key).

Yes, it certainly is. But the reason may be a failure of some to understand and appreciate "the pin 1 problem" -- that is, the mis-termination of shields within equipment. Lots of ham gear, including

Huh? My response is directed precisely at the technical problem at hand, and in precise technical terms. Until you understand the BASIC problem it's hard to come up with a rational solution. I'm sorr

Memory is, indeed, flaky. Perhaps your experience on Field Day was with an Omni VI or VI Plus. The Omni V does not have an internal keyer, and has only a single keying input -- an RCA connector mount

There are some excellent tech articles on this topic on the ARRL website. I strongly suggest that you read them. The executive summary is that 1) the more radials the better; 2) the longer the radia

Read the specs on your Astron. An Astron 20 is NOT rated 20 amps continuous, but an Astron 35 is. Isn't marketing wonderful? Jim K9YC

Did you study any of the many excellent technical articles published by ARRL on this topic? Or did you simply wait for others to agree on a simple answer? Understanding is achieved by serious study.

Right. This is UTTER BS! Sounds like a pin 1 problem! Ten Tec gear is full of pin 1 problems. Yes, winding the keying line around a ferrite can be a band-aid for pin 1 problems. The catch is that tor

If you have RF feedback, it may be a pin 1 problem. Cable shields should go to the chassis, NOT to the circuit board. All the TenTec gear I have takes them to the circuit board and not the chassis, w
