41. RE: [TenTec] Re: Model 253 Autotuner (score: 1)

The auto tuner seems to need a new eeprom after repeated auto tuning...say about a year. The fix for this was to put a socket in for easy replacement of the eeprom (Ten-Tec). This shows up as a loss

That's correct. I noted that it gets used up after repeated auto tuning...I meant repeated retuning for lowest SWR. I figured my tuner was typical...sounds like it is. Chuck, KE9UW -- Outgoing mail i

I'm using the TT253, but I think the LDG AT-1000 at $599 would be the way to go. It will do for the Herc II power level. I would have gotten one by now, but the 253 will handle my Drake L7 when it's

I believe if you don't select a band, the tuner has another four memory settings. That makes 32. I looked into this a few years ago...didn't recheck this but I believe I used the non band selected fo

I would guess that the MARS frequencies above 4 MHz are why they have a LP filter for 4 to 6.5. Chuck KE9UW -- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.gris

I can tell you that reversing the Omni 6+ power with the radio on or off will only damage the oven for the ref. crystal. By the way, does anyone know how much the TCXO for the 6+ costs and if it elim

What you need is a 16 line to 4 line encoder. Just off the top of my head, this would take a pair of MC14532 cmos encoders configured to a 4 bit output using a 5 volt supply. The output of the Yaesu

Actually I think a great benefit is from reducing crosstalk from adjacent pairs. The benefit of twisting tends to be significant up to around 30MHz...by one account I read. Chuck, KE9UW -- Outgoing m

No. It gets a little warm, but not hot. It's big enough...maybe even somewhat bigger than 50A, stud mount and just in line with some heat shrink tubing over it. In sideband service, the average power
