OK, I'll fall for it, how does a cable have a negative dielectric loss figure? 73 Bob, K4TAX Be careful using those "additional loss due to SWR" tables; in some circumstances the unmatched cable loss
Good explanation and I do see the reference. Thanks. 73 Bob, K4TAX At HF the losses in most transmission lines are copper losses, not dielectric losses; so the losses are directly proportional to the
Did you check with Stan at Tentec Sales? There just might be one or two around. 73 Bob, K4TAX No longer on TenTec site. Any used ones out there? Tnx Jim N4BE Sent from my iPad _______________________
I agree with Jim on this. Yes, all 5 of my supplies, switchers and linear ones, have had grounding issues mostly the result of PAINT! Be it paint where the 3rd pin ground wire attached to the chassis
Well, lets see if I can answer those questions; ** See embedded text. Carter, That was an excellent question and Carl gave a great answer, but it is also a little more complex than that. My questions
Mine has the black knobs. Radio is about 9 mos old. No issues. I have experienced on other Omni VII and other models issues where the front knobs got bumped thus forcing them against the panel. I fou
Although perhaps a good suggestion if a spare connector is available, I can't say one should use the connector on ones radio. A bit too much heat and one might have a 2 piece connector become "one pi
Yep, I'd say this is nice package deal with radio, PS and filters. I view it smart to ship via Fed-X. I had my Eagle recently damaged by UPS during transit. It was double bubble wrapped and double bo
Having found it necessary to replace one of my encoders, I took it on myself to see exactly why the other one failed. There is a rubber or synthetic material ring inside that is used to provide dampi
Seem to recall that Tentec has a "Y" type connector that will allow one to use two devices such as a soundcard and amp keying line. Also, seem to recall the amp keying accessory {318} has a 2nd DIN t
That certainly makes it easy to use standard cables, or easy to make cables to connect ones amp, plus use the soundcard of their choice, plus use a foot switch, or a straight key. Everything is cover
I always bubble wrap an then put it in a snug fitting box. Then that box goes into a 2nd box which is about 25% larger with the voids between the two boxes filled with peanuts. 73 Bob, K4TAX I assume
Ken et al; I seem to recall the shipping companies standards do expect the contents of a package to survive a 3 ft drop, landing face flat on a solid surface on all 6 sides and survive a corner crush
The PIV rating on the original component is marginal. 73 Bob, K4TAX Diodes don't usually fail without a reason. The reason is often a failure of some other part. Yes it would definitely be wise to ch
What ever level it takes to keep below the ALC threshold would be the correct power level. Same for the 100 watt rigs too. However, with the Argonaut VI the ALC circuit is of different design and one
Yes, RTTY is a carrier mode much like CW. PSK is an analog mode as most use it. Therefore linearity is very important to transmit a good quality signal. Bob, K4TAX Sent from my iPhone
Real FSK is the carrier being shifted between two frequencies, thus Frequency Shift Keying. There is no tone being transmitted. AFSK is two audio tones being transmitted, thus Audio Frequency Shift K
Yes one can run any stages in class C with a FSK signal with no issues. In order to have IMD issues there must be 2 or more signals present at the same time. With FSK only the carrier frequency exist
