ya know, i didnt think the diff would be drastic but i got more than 1s unit on all the locals a little farther out. this is just supposed to be a one-off experiment for sh1ts and giggles and it ended up being my full-time base antenna

so how i keep the shape of a folded dipole was to wrap it lengthwise across 2 sections of PVC conduit to make it easier to hang vertical. so far i have not encountered any other CBers going this route.

i had some coax on the shopping list but this was just a very successful experiment and i now cannot justify the cost of that long of a run of LMR600. i want some other people to mess with it, maybe optimise it some. a folded dipole is resonant, but at about 200-300 ohms so most people use a...

close enough for govt work i guess. no higher than a 1.5:1 across 3+ band segments

because it's what i had laying around

got rid of the 150' run of rg8x into the big pine tree but instead of dropping an arm and a leg on lmr600, i decided to give a folded dipole and 450ohm windowline a try. running a 9:1 3kw balun right behind the radio room. dropping the feed loss from 42% to 5% is HUGE. so no more coax outside...

i would make a fullwave loop and a director myself if it was a huge dish.

i like to use the PA switch for stingers or rfx units because it goes from "public address" to "power amp"

sounds like the perfect easy conversion for something like an echo mod or a diode-switched channel kit oscillator

i like repurposing them for other mods myself

ok i got tied up with other things like shoveling snow. SO ANYWAYS: ALWAYS use mica insulators on TO-220 transistors. i threw a cheap rubber insulator behind the NPC-RC darlington bolted to the case, jabberjawed for hours, and it apparently failed so im just gonna swap the 4003 diode to be...

i just put a partspigged one in. still getting something pulling from it so now for my next trick, gonna change out all the parts connected to it.

looking at the schematic, i got more questions now. theoretically if i was in PA mode i wouldve shot that voltage throught the transformer on the primary, but i dont think i was in pa mode. so maybe the secondary sh1t the bed just because....idk it felt like it?

yea, the rfx is fine. not really looking forward to that labor or for the recap, mods, etc i already did to go into the trash. such a waste of time. im not looking to throw the rfx on a junker either, the rig really looks good, and its an older sidemic. also, the serial number tag on this got...

ffffff. so i just put a new choke, power connector etc on my 29, extensive work incl a rfx has already been done. goofed up and there was a solder bridge, from the pad that recieves the power from the harness to the positive pin of the PA jack. now the modulation transformer gets hot and smokes...
