I didn't look at the C II but the Omni B/C and Corsair 560 all appear to have a dedicated (isolated) bandswitch wafer tied to the "linear" socket on the back panel. If' I'm reading the schematics rig
Since we're doing some "what-if" here: Instead of a frequency counter, how about using a DDS VFO in an _external_ enclosure - set up along the lines of the 301/302 remote tuning knob ? The VFO jumper
A couple of points off the top of my head if I'm remembering correctly: 1) I think a main expense for ladder filter production would be the requirement for crystal matching: the more closely the reso
The lattice vs. ladder may be a point on the JA rigs. The other item may be the presence of digital artifacts (synthesizer phase noise etc.) which can "color" the audio. 73, Al
A quick check on line looks like it was designed for/used in TV tuners. Worst case you might be able to find one to "re-purpose" in a TV set of that era? 73, Al
(First, standard disclaimer: I can't justify buying one as a casual operator/ragchewer, but others who are more serious about the hobby obviously are willing to spend that much on a ham rig.) Put in
Tim, It should be fairly easy to replace the speaker with something off the shelf from Mouser etc. once you determine the specs. I doubt it's anything exotic. 73 es GL, Al
That's why you need a vehicle with a manual transmission (or one of the older design automatics with a rear pump so it can be push or pull started) for your outings and that you make sure the vehicle
John, Not to throw a wet blanket on your project, but in addition to finding out what the construction of the roof is (wood or metal) I'd also suggest doing some "sniffing around" with a portable rad
Greetings all, I have an Omni-C that's been sitting here for a while and probably needs a new home. It's basically functional, but the PTO needs attention as it's stiffer than normal and not smooth,
Doc, Maybe you've checked these things before, but if not: 1) Make sure the rig isn't accidentally in transmit mode (something leaning against the key or mic switch, "TUNE" activated, etc.) 2) Make s
Pete, After thinking about your post I'd suggest re-thinking your situation. You are dealing with two different issues: the first is the encoder issue; the second is in my book much more serious -- t
First rule of troubleshooting: check the simple stuff first. Case in point: I was at a local auto shop recently to get a new set of tires installed. A couple of the mechanics were discussing a proble
I've owned a couple of K2s over the years and scratched my head quite a bit over why the IF/AF filter selection system was set up the way it was (filter selection stepping wide to narrow, requiring "
If it's been sitting around for a while I'd suspect an oxidized connector or an electrolytic that needs to be re-formed. You might just power it on and let it "bake" for a day or so to see if that do
"QRP-eliminator"? Does that mean it filters out any signals which are below a certain TX power output? Guess I better stay away from that one!!! SRI, couldn't resist HI HI!! 73, Al ....
Slightly OT but there is also a motorsports-oriented company owned and operated by the same folks as DXE. Same "above and beyond" customer service from them also. (If you're curious who it is look at
