Looking for dead 444 hercules. Closer to Atlanta 30332 is better. 73, -bob ah7i _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/m
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

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
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
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
1. Does anyone know the I2C clock speed in the Eagle 599. 2. I have two and a half Eagles. One of the two complete Eagles is misbehaving with regard to the multi-control. I don't want to replace the
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
Back story: I bought a dead Eagle expecting it to have a good tuner board. I've repaired everything except the tuner board and the FRACN Synthesizer board. Wanted: 1. Another dead Eagle for parts. Ho
I modified my Eagle to replace 12 V with the key(transmit) line at one of the two 12 V accessory RCA jacks on the rear panel. So, I no longer need this little cable. Center pin of acc to center of RC

An electric fence charger may be modified for a longer rise time. Like softening keying to eliminate clicks. 73, -Bob ah7i em73ts _______________________________________________ TenTec mailing list T
Try another email or give TT a call. I recently purchased buttons and a synthesizer board for my Eagle. Price was reasonable. TT does not have the springy foam for the Eagle, only the buttons. Three
Ron, Have a look at the Ten-Tec tuner schematic. It's a slave to the CPU. It has some line buffers and serial to parallel latches. The ATU-100 has a controller, relays, and reactances. Clone the Ten-
Aloha all, Today I collected an Argosy 525. I have not checked out TX. RX is outstanding! I can not believe how quiet the audio is. It's got two 8 pole filters 2.4 and 0.5 kHz and the calibrator boar
