Thanks guys. It looks like the control. Resistance bobbles around 10k instead of the 100k it is supposed to be. It's also erratic over the arc of the resistance portion. I can't find photo of Bob's f
Thanks everyone! Got it working. I replaced the encoder with a new one. Took the old one apart and there were tracks of something following the path of the wipers. I'll clean it up and use it for ano
HDDD! Three more dB over the Herc. Doing a preliminary checkout now. It's very pretty. It has RF parts tubes. photos at google: https://photos.app.goo.gl/rYnEB9YVQvFWLd4X8 Does it have the 'problem'
New to me Centurian. I was a bit surprised to find a 15A and a 25A fuse. 20 A x 2 is specified for 230V so I replaced them. Total is the same :-) Here is what I see with a 50 Ohm dummy load and the C
Hi Carter, I'm more inclined to suspect a resistor, cap, or connection in the metering circuit than the load. I should have a new fan here in a week and will find and fix the other stuff while the co
Does anyone have a copy of more recent schematics/parts lists that include the later revision boards? I'm trying to confirm replacement parameters for the part labeled CT237Z on the CPU board. 78378
Dr Vic, you may want to consider antenna change along with roof change. A trap vertical on a metal roof has worked very well for me. Radials lying on the roof provided plenty of coupling. Try an inte

I bought a dead bird for it's tuner and possibly other parts. Tuner 80m coil and one relay show signs of overheating. How to remove white silicone rubber in order to inspect more carefully. Thanks. 7
I've been using a HP server supply, 12.5 V 100A or a marine battery to power a Tentec 420 amp. I'd like to have the collector voltage at full spec so am considering a Meanwell 15 V 100 A supply. If a

Looking for CHEAP Eagle for hacking on. Receive must work. OK if transmit is dead. Need not be pretty. If you have one, please let me know $ to my 30306 address. 73, -bob ah7i -- -do not look into LA
I have not used an Omni VII. Having used the IC7300, Orion, Orion II, and 599 I'll testify that when it comes to hearing a weak signal in the noise... the Tentecs win. As for market. The Elecraft stu
Hi Gary I used a surplus computer server switching supply on mine for a good while. I like having circuit diagrams for my gear and after some effort and no success in finding one switched over to a b
