You handled it just like I would, James, and I've repaired communications equipment, LF through microwave, professionally as well as built countless kits and scratch-built Ham rigs, many of my own design.
I don't know if the fellow behind "The Smiths" built his K3 from a kit, but you and I both know that replacing the RF board is a big job involving completely disassembling the K3 back to a "kit" except for the front panel assembly. I've done it. Time is required, just as with the original assembly. Rushing, while assuming one remembers exactly what to do, will certainly lead to time-consuming mistakes. RF chokes on leads leading outside the rig are for RF suppression - to keep RF in or, in this case, certainly to keep RF that might trigger the circuit out. You'd know instantly if there was a problem. Your rig would key when you operated something else, or stick in transmit if it's own RF trigger the key line. In your situation I'd replace the choke too, but if it were too difficult to get to, I'd add a similar value choke to points I could reach physically as close to the existing choke as possible. 73, Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of James Sarte Sent: Sunday, November 14, 2010 12:54 PM To: The Smiths Cc: Elecraft Reflector Subject: Re: [Elecraft] K3: Right paddle key not working? Well, time is always an issue for me. This weekend I was lucky as I didn't have to work. I was able to troubleshoot the radio and figure out what the problem was. I guess what I'm trying to say is, I'd rather take my chances replacing the choke myself then spend hours tearing the K3 apart, then putting it back together again, hoping that nothing else would be wrong with it once I'm done. I did put my K3 together as a kit, so I do have experience working on it... it's just not something I look forward to doing. In the little time I do have to play radio, I'd rather play than fix. :) 73 de James K2QI On Sun, Nov 14, 2010 at 3:38 PM, The Smiths <[email protected]> wrote: > > Of course if time is an issue, and it doesn't seem to be in this case as > we've seen you trouble shoot, then soldering to repair, and once again > jumping the choke to "test" with.
