381. Re: [TenTec] Corsair II QSK (score: 1)
Author: Steve Hunt <steve@karinya.net>

Problem solved. A 4.7uF capacitor had been fitted at C54 on the IF/AF board instead of 1uF. It looks like it was there from new. The previous owner didn't use CW so he'd not noticed! 73, Steve G3TXQ

Thought you might be interested in another fault I found today on my new "bargain" Corsair. Symptoms were that I set the S meter to read S9 on a 50uV signal, but if I then increased it by 20dB the S

Bob, You're right - diagnosing a wrong-value component was more difficult than a faulty one. One of my problems was that there is no parts layout diagram for the board, so even when I discovered a 4.

I was trying to copy a weak CW signal yesterday, without headphones on, and noticed just how intrusive the sound of my Hercules II cooling fan is. I don't think it's any worse than when it was new -

Mike, Thanks for the input - I think I remember reading somewhere that the original Hercules was noisy. However, Bob Good advises that his Hercules II is quiet, and I just found a 1990 CQ report wher

Thanks, everyone for the useful suggestions on my noisy fan problem.. The consensus seems to be that this is NOT normal, so I now have several things to try. By the way, TT Service advises that the f

Today I did a few checks on the present fan. 1) I unbolted it from the under-tray and held it in place by hand. There was no reduction in noise, so I don't think resilient mountings will help. 2) I r

Well, the new fan came today - an Orion, would you believe. I soon had it fitted. Result - slightly noisier than the original one - oh dear! While checking everything over with the new fan I ran the

Jim, That table could be very misleading without a lot more info. For example, is it showing the total loss, or the "excess SWR loss"? What type of cable is it for? And what length? At what frequency

I guess it all depends on what you mean by "the antenna" - does it or doesn't it include the impedance matching components? My personal view is that if you talk about a "tuner" you are talking about

As Jerry points out, there are some amongst us who believe that a tuner at the antenna feed point tunes the antenna wire to resonance. It does not. Why not? The tuner can supply the needed series cap
