For RX issues, one thing to check is the slide switch for AUX RX - RX ANT....sometimes corrosion sets in resulting in high resistance and NO RX... Also if the switch is in the AUX ANT position with N
Probably the sampling diodes on the SWR board. Get some 1N34 diodes (if I'm remembering correctly) and replace all on the board. A nearby lightning strike probably damaged one without causing any fur
The lamps just failed (04/20/19) both failed so they must be in series, if the circuit is 28 VDC and the lamps are 2 X 12 VDC. Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windo
This one was new old stock from AD0S... it is an export model that I bought from him the year TT brought out their first updated model of the 425 at Dayton. So it is an early version. I have three Ti
Motorola rf power transistors... you should be able to get replacements. 73, Gary - AB9M Sent via the Samsung Galaxy TabŪ 3 Lite I let the smoke out of my beloved Omni 6 finals. Any leads? Any parts
Are the 9 Mc filters in or jumpered with the correct jumpers for output? Gary - AB9M ________________________________ From: TenTec <tentec-bounces@contesting.com> on behalf of Stan Gammons <s_gammons
The question then, is the jumper appropriate for the loss of the filter? I had a OMNI-6 plus for ten years (two optional 9 Mc filters) and changed them from 2.4 Kc and 500 Hz to 1.8 Kc and 250 Hz. I
Make sure the memory back up (9 volt battery) clip is not shorted if you have not replaced the battery. Also check the wire originally twisted into a loop... if its cut, the rig will transmit almost
The first thing I would do as a owner of similar (Corsair II with 263G VFO) equipment is set the internal and external VFOs to different frequencies, then determine if RA and RB are working (not RAB
If the display is reseated one pin off, you may find the display driver transistors and other components will need to be replaced. (don't ask me how I know) The parts are all common and can be replac
Rick, while I'm currently satisfied with my OMNI-VII w/ Flex-1500 sub-rx (N4PY mod), Corsair II w/ 263G, 715, 253, and 425 (export), I know the day will come that, I'll be looking for a new rig... it
The Flex-1500 (which I have) will do binaural using the IQ stream. The FLEX-5000 with second RX will do Diversity. The FLEX 6700 does Diversity while the other two 6000 series are binaural capable. A
Old TenTec built the crystal ladder filters by bulk purchase of the basic crystals which were apparently sorted into lots of high, on, and low, (as indicated by color dots) groups for the filters. At
You do need PowerSDR or HDSDR controlling a SDR... it doesn't have to be true Flex radio. N4PY may be the better option. 73 es DX, Gary - AB9M I Sent via the Samsung Galaxy TabŪ 3 Lite I thought DDUt
Then its probably not the diode problem. Have you tried operating the ALC, Process, and Drive controls to clean any dirt or corrosion from the pots? I periodically operate all the pots and switches o
You are welcome Steve. I also have an Omni VII, which is my primary radio. It did take a learning period to get comfortable with it... and it too needs to be used to avoid corrosion in the encoders.
Agreed. 73 es DX, Gary - AB9M Sent via the Samsung Galaxy TabŪ 3 Lite It would indeed be unique and fill a niche in the market. No DSP. The PTO could become DDS with a serial port. No PLL. My Corsair
