[Elecraft] Time for a new Volume pot?
The volume knob has gotten very, very touchy lately. Very scratchy when adjusting and suddenly blaring at top volume. Is it time for a new volume pot on my K2? 73, Bill Allen - wa5pb K2# 1068 -- No virus found in this outgoing message. Checked by AVG Free Edition.

Bill, It certainly does sound like your present volume control is worn out. Replacement is likely easier than trying to 'monkey' with those 'restoration' fixes IMHO - I have never had much luck with the sprays, drops and other stuff that is supposed to repair controls. 73, Don W3FPR -Original Message- The volume knob has gotten very, very touchy lately.

RE: [Elecraft] Time for a new Volume pot?
From the serial number you might consider making the audio gain pot mod while you're in there if it hasn't been done yet. It makes a huge difference in how the audio pot operates, making adjustment less touch even with a new pot. On the Elecraft web site, go to Builder's Resources / Application Notes / K2 AF Pot Application Note for details.

RE: [Elecraft] Time for a new Volume pot?
Brent, Since you asked, the pot replacement is actually rather easy - just take it one step at a time - first remove the front panel from the K2 (don't forget the screws from the control panel to the front panel on the inside); then remove all the knobs and the one screw next ot the VCO encoder to separate the front panel board from the metal panel. After that, remove the pot itself in whatever way you remove such soldering - if you do not have a powered desoldering tool, I suggest that the easiest way is to destroy the existing pot (no sense in preserving it, you were going to throw it away anyhow). With a set of heavy diagonal cutters, first cut off the 3 pins and then crush the pot body a bit so you can cut the two mounting ears off - after that, you can easily heat the stubs left in the board pull them out - clean up with solder wick and put the new pot on the board - re-assemble after doing the AF Gain pot wiring mod (if applicable). And as Ron pointed out - if your K2 serial number is less than 3000 (probably is if you are replacing the pot), make the changes for the AF Gain pot wiring mod - it will make a difference in the future for longevity of your new AF gain pot and makes the AF Gain control less 'touchy' and less noisy. 73, Don W3FPR -Original Message- Don could you give some guidance concerning the replacement.
