Very interesting Jerry. I so something similar here as I use an Astron 35 amp ps and a rigrunner power distribution system. I can then just plug-in whatever rig I choose. Very convenient. The rig run
I have been doing some work on this matter for a while and have identified two different issues. Thump and Pop. As you say Paul, the thump occurs on keying. As I recall, it occurs upon opening the ke
Then too there is the Argosy series. Nice, simple and economical radios. If going that route, be sure to use one that has the diode ring mixer, not the IC mixer though. I don't know exactly when that
What you read for SWR has a lot to do with the calibration of the detector. When I installed the internal tuner in my Jupiter, I matched the Ten Tec and the LDG detectors so they both read the same.
That procedure at Alpha looks good to me. I've been using the AL- 80A with PIN T/R for over 10 years now with the Corsair, Paragon, Pegasus and Jupiter. That's exactly how I do it on all the rigs exc
Paul, As far as I know, the PIN switch in the AL1200 is the same as mine in the AL80A. It is spec'd to switch in less than 500 microseconds. I have taken a very close look with scope and found the am
The Ameritron PIN-5 TR switch that I use draws less than 2 mA current and has open circuit voltage of around 12 volts. No problem for the Ten Tec switching transistor which is rated may times that am
I think I can understand what is happening here. The following applies if the PIN5 switch is the built into the amplifier. If it is an external box, some things may be a little different operationall
George, opinion is one thing, but when you make absolute statements like your last post, you should be able to back them up with facts. I doubt you can............so why don't you just keep your thou
Hi all, I'm looking for a main tuning dial bezel for the Argonaut 515. I think it was also used on some of the other rigs like the Triton and Omni. Anything out there? -73- -LeeWA3FIY
One thing we may be missing here, is that, based on published specs and features list, the Orion is in a class by itself. Therefore, cost comparisons are of limited usefulness. We will have to wait u
As you point out Paul, two very important specs are Phase Noise and close in Dynamic Range. There are some interesting numbers regarding the CorsairII and some of the other rigs mentioned. Unfortunat
I concur. May be one of the best kept secrets around. I like to have an RF gain on a receiver so I simply wired a 500 ohm pot between the antenna cable and the antenna input connector. Really helps w
One other matter to carefully........and I do mean carefully.........consider is the maximum volume level available at the headphones. It should be standard practice to limit the maximum volume at th
Bob, I know you addressed this question to George but I hope you don't mind if I respond also. I run a rig here I call the "SuperJupe". I thought of calling it Parater or Jupiton but I liked SuperJup
Ooooops! In my earlier post I wrote "The result is a receiver with five stages of good crystal selectivity prior to the signal arriving at the DSP...". Guess I was in too much of a hurry. What I mean
