201. Re: [TenTec] Orion/O2 Drift Problem-who is interested in a fix? (score: 1)

I am using an HP 58540A GPS-disciplined OCXO with another brand of transceiver. Of course, stability is excellent but even the best GPS-based OCXOs are phase-noise-limited to about -145 dBc @ 1kHz.

There's never been a better time to be a part of this hobby. When I think back to the early '70s at a time when I was a novice at age 12, it seemed like we were living (and operating) in the dark ag

The Omni Six's external keying relay will switch this voltage and current, but I recommend using a solid-state switch or high-voltage output transistor keyed from the TX OUT.jack using an RCA "Y" ad

Same here... When I owned an Omni Six, I decided to modify the external amp relay circuit to support a super-fast, high-voltage key line for use with an Alpha Seventy amp. The Alpha uses a +55VDC ke

If the relay is fast enough, it is capable of real QSK. The reed switching response time of all Ten Tec's I've ever used can safely be put into the "real QSK" classification. The opto-coupler must s

Agreed. On most crimped connectors, I solder only the very tip of the stranded wire after crimping the barrel, provided there's solder access at the tip of the connector. Nearly all crimped lugs all

TX OUT/EN is fine for amps with such a handshake mechanism. But for QSK amps without this feature, TX OUT is a poor choice for a control line. In many amps, using TX OUT as the QSK control signal re

Dave, You are correct. The Omni VII's internal keyer comes close to a 1:3 ratio only when the CW weighting control approaches the top end at 24%. At that point, weighting is close to ideal, but stil
