Re: Low RF output on QCX-30

Hi Dave,

I'm a Michigan hillbilly (aka Cedar Savage) and we call that "shotgunning" parts. Just stand back and spray parts at it until it works. It's done in auto repair far too often.

I think it is very unfair to complain about a site such as WSPR.net on a forum such as this. If you have purchased software  and had poor service, then you have a right to complain. WSPR and similar digital modes like FT8 are free software that Joe and possibly a team have spent thousands of hours developing and then giving the amateur serice free use. Commercial companies would spend thousands of pounds/dollars/ what ever your currency is to get software as comprehensive as these digital signal processors.
A large number of amateurs download free software for their own use with no thought about how much time has gone into the developement of that program. How many have spent just a few moments to send the author a short email to say "Thank you ".
I admit that I am guilty of this but with some programs that I use frequently, I have been in contact with the authors and they have been grateful of the recognition they deserve.

QCX-20 No power output at all

secondchancesailor
 

My QCX-20 has no power output.  When I key down, I can hear the signal in my TS-440, and if I place a frequency counter near the PA it will read the output frequency.   But there is nothing at the RF output.

Initially, when transmitting on 7020, the output was actually on 7048.   I recently built a QCX-40 with no issues, and had to make just a very small adjustment in the reference frequency to put it on frequency.  But in this 20 meter kit, I had to set the reference frequency to 27,057,900 to get the output to match the displayed frequency - a larger error than I expected.        

So far, I have carefully checked the circuit board for any solder bridges or breaks using a magnifier hood, but found none.    Using the built-in RF Power meter to check the drains of Q1, Q2, and Q3 I read 5.2 watts, but I have read in other messages that that doesn't necessarily mean anything.   I have checked the continuity of L1, L2, and L3, and removed a couple of turns from each as has been suggested, with no change.    I can read 5.2 watts on one side of C29, but nothing on the side that goes to L3.   I pulled C29 and it measured ok, but I replaced it anyway, and still no output.     I have to admit that troubleshooting isn't really my strong suit, and I don't have much in the way of equipment.   Any help to point me in the right direction would be greatly appreciated!

Re: stiff encoder? Try WD-40!

A MDS on WD40 some year’s back said it was  white spirit, light machine oil ( like 3m) and a perfume . It was originally developed to displace water  on car and truck engines  when condensation on the ignition system had prevented starting.  But has found many other uses, some not so good.

 

The solvent part can do a lot of long term damage to a few plastics ( but not all plastics). A much safer and longer lasting option is  a PTFE lubricant spray. 

 

Many shafted pots and encoders use an anti-lubricant, a high viscosity grease which slows rotation and gives a nice “feel”  I.e. it stops it being floppy.  Sometimes a solvent like IPA will free up controls and then evaporate completely, or   a drop of light oil will work for a while.

Yes, and be sure to wear safety glasses whenever working on your radio!   ;-)

I'd certainly use WD40 if that's what I had.
Maybe paint  a bit on with the tip of a paper towel right where the shaft enters the bushing
that spray is hard to control.  I'd mostly be concerned about some of the residue
getting back into the contacts.  

Maybe alcohol would work, if all you need to do is free a gummed up bushing.

Many of us have products for locks sitting in a drawer these last few decades
that might be worth a try as a lubricant.

Maybe.  But I bet I could buy 10 encoders for the price.
