Don't forget the heathkit sb-104 True solid state with NO tuning. Even the TT 505 you had to peak the resonate control. Mike wb8vge Sent from my iPhone
rick, you need to insert one more item to your list right after operators Money! Lets face it, the guy (or club) that has the $$$ can afford to buy all the neat things that together win contests. I d
Check the bias voltage, too The circuit is supposed to track thermal increases from the PA transistors and adjust the bias voltage. Mike wb8vge Sent from my iPhone
I sure wish Ten Tec would make a limited run on some of the more popular bands. if nothing else, make the plastic shell parts. The pcbs wouldn't be hard to make Mike, WB8VGE SunLight Energy Systems T
DALE, is it off on one mode or all of them? Mike, WB8VGE SunLight Energy Systems The Heathkit Shop http://www.theheathkitshop.com/ J e e p o|||||||o A man with one clock knows what time it is. A man
Absolutely! No one that I know can do that by ear I have some rather high zoot equipment here on my workbench, but its hasnt been calibrated in a long time. Decades perhaps? I dont know. but for me,
Really? I mean really? Heck, Ive been told countless times Im off frequency. My hearing is shot so i tend to tune SSB in a bit higher pitch than normal. Ah WB8VGE, youre 27 hertz too low. Really? Yes
The first thing that comes to Mind is do you have plate voltage and standby current when the amp is in tx mode with no drive. Mike wb8vge Sent from my iPhone
Hummm Without the amp sitting in front of me, I'd say that with NO resting plate current is one mighty big clue. I don't have the schematic in front of me either, but some amps with 500z tubes had a
Personally, Id go with $250-$300 for the rig $100-$125 for the power supply $125-$175 for the vfo. Again, value, like beauty, is in the eye of the beholder. If there are holes, non-factory knobs, str
Define broke. Are you located so far in the boonies the only time the supply plane can make it in is when the river is frozen? I've had a lot if rigs on my bench, but can't imagine stocking very part
Im sorry, but had to chuckle.. packed by UPS, but shipped by FEDEX Thats nice radio and Im sure it wont be around for long Mike Bryce, WB8VGE the heathkit shop SunLight energy systems J e e p o||||||
back in the day, I ran RTTY on HF with a Triton 4. You ran it at full bore, keeping the ALC LED just from lighting. The limits were how the power supply could handle the 20 amp draw for 10 minutes or
Bob and the group I ran AFSK by squirting audio into the microphone jack. Exactly like we do with psk today. Linearity was just as important then as it is today. Mike wb8vge Sent from my iPhone
Without seeing the radio, I'd fall back to unplugging and plugging in the MTA connectors that drive the band pass filters and other band specific circuits. Sounds to me like the low level driver has
jim, pop the covers remove and then plug back in connectors 82 and 83 on the 81595 board (mixer) remove and then plug back in connector 82 on the logic board with your vom measure voltage on connecto
As far as I know, no ten tec PA folds back at high swr. They rely entirely on over current protection and shut down. Even with a LP filter board relay failure the PA should draw lots of current. Perh
Okay. I'am doing this from memory. The PA used in ten tec rigs plugs into the low pass filter board. That board is hard to get to or troubleshoot without saying lots of bad words. Make up a 3-5 foot
