Yuk! I've seen brown crud on the foil side of the circuit boards my Paragon and another one that I worked on. In those cases the crud was excess soldering flux. I cleaned it off with isopropyl alcoho
I've done it a few times. Mike is correct. Remove the small knobs, using the supplied Allen wrench (I think it's an 0.050). Pull off the outer chrome knobs and you will find the nuts which secure the
Snowy, I had a shorted bypass capacitor on the counter board on my Corsair that was messing up the logic that tells the counter what band its on. 73, Bob WB2VUF On 3/28/2017 11:38 AM, ROLAND HOWELL w
That's too bad. I'm really getting concerned that if Ten Tec stays out of the marketplace too long they may not recover. Especially when the economy improves and consumer confidence increases, hams l
I thought that the IC-7300 receiver was getting decidedly mixed reviews. I'm not keen on a touch-screen implementation. Interestingly, the IC-7200 is back in production. I like the MIL-SPEC look of i
Yes, AMP Mate-n-Lock. It should be available from Mouser and Digi-Key. Bob WB2VUF shawn kb1ckt Sent from my iPad Newbie on the list. I have an Omni-D that I'm currently troubleshooting for flaky conn
Yes, there are a couple of ways to disable the amp keying relay. In one radio I soldered a jumper from the base of the relay driver transistor to ground. I another I installed a miniature slide switc
If slotting the top doesn't work, file it off flat, drill out the screw and re-tap the standoff. Bob WB2VUF If you have a drill press, I would use a reverse, left hand drill bit. To subscribe or unsu
Joe: Don't despair (yet). You will have to open up the final compartment to see what smoked. Maybe one of the final transistors is blown, or maybe a capacitor shorted out. The MRF458 transistors are

Joe: I would replace both. There is some debate as to whether a matched pair is required, but I read somewhere, maybe on this reflector, that a matched pair is s good idea because it results in lower
Interesting parallel, Gary, I got very active in CW traffic handling and bought a Corsair because it was full QSK (unlike my Heath HW-100). I bought a Paragon for digital modes (AMTOR at the time) an
There is another problem with crystal and mechanical filters: Availability. Collins recently discontinued their filter line. With the DSP revolution ongoing, analog filters will become even more expe
That's amazing that people would buy and then dump them so quickly. There must be several things that are disliked, like maybe they can't get used to using a touch screen. I, myself, would prefer tra
Just an FYI, in it's cousin, the Century 22, Ten-Tec replaced both the MRF-476 drivers and the MRF-475 finals with Mitsubishi 2SC1969, due to high failure rates. The 2SC1969 is also available from RF
Yes, I had to solder a jumper wire across the power switch terminals in my Corsair when the switch burned out. I'd like to find a replacement some day. The power switch in the Century 22 is prone to
Well, isn't there a mid-grade radio between "entry level" and "contest grade"? I consider entry level to be the Alinco or the ICOM IC-718, both under $1000. For $1500, I wouldn't expect a super conte
So I shouldn't trade in my Paragon? -Bob WB2VUF Direct sampling is a new technology. This is not an entry level radio, it is an entry level radio into the state-of-the-art direct sampling world. Simp
Yes, there is no other fix. The nuisance part is desoldering and removing the shield covers on the underside of the PLL boards. Go slowly with the solder reflow work and be patient and you will be re
Bill: I had the same problem with the 500 Hz filter in my Paragon. Selectivity was fine but insertion loss was higher than the other filters. I swapped in the 500 Hz filter from my Corsair and it was
