Hmmmm... for a process as relatively simple and inexpensive as retrofitting some op-amps, I'd wonder if it would be worthwhile in other TT rigs of that era which use the 4136? 73, Al
Noting that I'm somewhat of a Spartan/minimalist mentality as well as being a tightwad, my approach would be "drive it 'til it dies" (i.e. is unrepairable or not cost effective to fix) if you like it
Steve, I've used a super simple approach for an outboard CW filter with older Ten-Tecs: an 88mH telephone toroid in series with a 0.47uF+/- Mylar etc. non-polarized cap, with a low-value pot or selec
I won't get into the Windows vs. *nix debate (although I personally use and prefer Linux.) However, I would urge Lee if he wants to stay with Windows to upgrade to at least Windows 7 as Vista hasn't
Simpler than that - just take a small section of a piece of 1/8" or so ty-wrap and wedge it into the gap opposite the side where the set screw is. I've successfully rescued several of said knobs that
The quickest way (but probably not the easiest) would be to try someone else's known good modules in the Scout and/or try the modules in another Scout/Argo. Otherwise, the rig/questionable module(s)
There used to be several on this list who did third party service on "classic" TT rigs. I haven't seen any posts from some of them for quite a while. Is anyone still doing this, or did they close up
Another option would appear to be the Weber Tribander. It would be nice to see something like that with a Ten-Tec logo (but I don't know how economically feasible bringing back T-Kits might be....) 7
<snip> All that walking you're doing to meet your daily step-count goal could soon start paying off -- and not necessarily in the way you expect. Yes, it will it make you healthier, but it could powe
From what I've seen (these are all duals, there are also quad versions of most?) the NE5532 is noted for a good price/performance (low noise) ratio for an AF active filter. The LM833, TL072/82, and N
Ron, I'd check the multitude of small connectors going to the boards in the front panel area. Mine was doing some random squirrely things and reseating connectors as noted seemed to take care of the
Bob, FYI there's a 208 filter (don't know if it could be adapted?) and a 206A calibrator listed on eHam Classifieds as of a couple days ago: http://www.eham.net/classifieds/detail/487436 Disclaimer:
A couple of things: one, encourage folks to particpate in this reflector. There's a wealth of "brainstorming" knowledge here to help users solve issues, even those not directly caused by the rig itse
OK, I need to jump in here. I had held off posting this because of the amount of traffic on this subject, but the cost to the company is more likely much higher than that. My source? a friend of mine
"12 mph?" Back in the 1970s I worked as an operating/maintenance engineer at a TV transmitter site in NW AR. A "tower ape" came out to do some work (tower lights if I remember correctly.) There was a
I think this is the one Rick is talking about: Simple Multi-Band Vertical Dipole http://www.dj0ip.de/vertical-antennas/simple-multi-band-vertical/ 73, Al
This is just off the top of my head (can't find anything in a quick web search), but I seem to remember something about aging/deteriorating bypass caps (especially electrolytics) in the display subsy
