I made mine with connectors I keep on hand. See links below...

I have no words for this!!!!!! This guy builds amps for a living and thinks Biasing does not work and it all sounds the same. I bet he does not have a simple china scope to see what happens with an RF signal.

Glad its all Ok. Those are really nice supplies, I have many of them. You can set the voltage the same parallel them for more amps too.

I figured it was a mistake so I mentioned it. Nice Rigs.

The pictures show a FT2000 and a FT1000????? What gives.

I like to break up the power distribution wires on the 12 volt buss so the transistors get good amp supply and voltage supply equally.

I have had a few of those. Neat little rigs. The CB guys didnt like them because it only did Upper Side band and CW so not many got molested by the golden screwdriver tech.

That depends, I have seen anywhere from 850-ish to 1250 on the output transformer for Toshiba amps. Both my FB HG amps have 1000 on the output transformer, even my old Twelve pack re pilled to DEI seem happy with the 1000 as well. Different transformers and wire wraps will change the tune some...

It looks like a center scribe tool.

Monitoring 27.375 here. Good luck to you with the cold.

I have seen people do this with amp boards. They dont realize they created capacitance when they do that, copper strip with tape/glue holding it to the copper main board.

I have pretty much read everything w8ji has written about antennas over the years. His info has really helped me with many things radio. His info on the Lazy H antenna really helped with that project, the other info I found on the net was not working as intended, a lot of bad building/specs info...

Here in NE Texas we had about a 1/4 inch of sleet on the decks when I got up, then it stopped the sleeting and the rain started, this is not good as I can see it freezing to my lines coming from the power pole at the street. It need to go back to sleet in a hurry!!!!!

Liking all the relies here. All good info for those that did not do this with their vertical. I use an isolation balun/choke/transformer (whatever your terminology is) on all my verticals. Never isolated my Imax from the mast, only the Maco has that. Perhaps I should give it a go for the Imax...

I use variable caps to test and get the tune right then I put in fixed components. I repair a lot of stuff for the locals and what I buy thats broken. Never built one from scratch but I have rebuilt many that were in bad shape and had mismatched everything. I did buy a 8 pill box kit from ICA to...
