Finally, a problem that's not of my doing. I loaned my Lincoln II+ V4 to a friend for a week for him to try out. When it came back to me, it would not even turn on. I think he may have had a high SWR issue or amp issue, but really could not be certain and ca't get a straight answer. All I had to...

Agreed. I tried it out and my 60 watt soldering iron is too wimpy to get enough heat into the 6 AWG wire to make a solid joint so I will stick with 8 AWG. I know I have a Weller 200/300 watt soldering gun packed away somewhere but it's been at least 5 years since I last saw it. I will find it...

Because I caught a bit of grief here a few months ago when I mentioned extending the #8 wires and it was suggested I should do it properly and completely replace the #8 wire with #6 wire. Plus it's another excuse to tinker/learn. ;) It'll be better once the weather warms up and I can get back...

Sorry to pester you with yet another question but... In general, does a slip-on ferrite bead work better than a clamp-on one of the same dimensions? I'm thinking of any stray RF weasels that try to sneak up the slot where the two halves join.

Thanks for the link. It looks like this one should work as long as I can mount it on the cable just outside the case. It has an ID of 0.505 inch and the OD of the 6 AWG cable I am using is 0.4 inch.

Does the bead have to be inside the case close to the solder point where it is now or will it also work if it is just outside the case? If it is outside the case it looks like it gives me more options for size/length/number of them and also clamp on too instead of just slip on. The clamp-on...

Mainly because I don't know this type of basic stuff yet. I have a lot to learn.

Thanks for the info. I will do some digging and see if I can find one that looks like it would be a good fit for the new 10mm 6awg cable.

In case anyone is interested/curious, this is the fan that came in my new 200HDC. I'm going to see if I can find a different fan that fits, keeps the amp safely cooled but is a bit less boisterous when doing so. Who knows, this may turn out to be a snipe hunt but I won't know for sure until I look.

I am in the process of replacing the much-too-short 8 awg power cables on my 200HDC with six foot long 6 awg cables. The outer diameter of the new 6 awg positive cable is 10mm and this is too large to fit inside the ring that the current 8 awg wire goes through right before where it is soldered...

Are you able to use the 300P on SSB at all? If so, how does it sound?

I ended up deciding to swallow a bit of pride and stubborneness and sent the radio to a service shop a few hours away from here. Hopefully the tech there can get the radio back to a solid starting point and I can avoid repeating the errors that contributed to it needing service in the first place.

The only identifying marks I found on Q109 are on the back and they are "02314" on the top and "F 1H" on the bottom. My initial search turned up stuff like the following light reading. ;) Or how about an octopus hook? :) I'll continue looking after work today.

No, Q109 has not yet been mucked with by me. I'll see if I can pull a part number off of it and do some digging. Last week I invested in a 10 power and a 30 power lighted magnifying glasses. I have joined the gang of geezers that can't read all that damn fine print anymore. Could be much worse...

If I were to hazard a guess, I'd say the pre-driver transistor is the one on the left side just around the corner from the other three IRF520s (circled in blue). If so, it was replaced too.

To be honest and to show my ignorance, I don't know what that looks like, where it is located or how to tell if it is good once I do find it. But I'm definitely game to try. To try to resolve the SSB voice distortion, I replaced the four circled IRF520s with Vishay-branded ones from DigiKey...

SSB modulation was fine before I started having the feedback or whatever issue it should be called when testing the Carl Built amp (not its fault!) with the Q5N2. Ever since then, the SSB modulation can best be described as crunchy, choppy like when you're using a crappy amp on SSB except this...

The Tekpower supply finally arrived after a week's delay. The Megawatt S-400-12 I ordered on Feb 23 also finally arrived today. It was stuck in the Big Bear Lake, CA post office for a week or so due to the blizzards and road closures. That area just got hammered by snow. Anyway, I followed the...

Very nice! Although my twice surgically repaired lower spine aches just seeing you digging the hole.

Thanks for the advice linearone. I've seen ferrites mentioned a lot but was not quite sure why/when/where they are used. The antenna feedpoint is about 33 feet up a pole so this will have to wait until spring and the snow/ice is off the roof and I can take the antenna down. I am hoping a tilting...
