Thanks for the info,, old thread post is 9 years old.

simple dipole will work no ground plane needed use it horizontal or vertical

Few years back I built a 1/4 wl GP and it worked great, as you have noticed improved rx and tx. direct feed no loss in matching network. I run my coax inside the mast pipe, think starduster type antenna install. this shields coax from rf and I have not noticed any CMC , have friends running this...

try it and see imax or a99 pick your poison,

maybe as cycle picks up it will get better, worked tonga last cycle on 10 meters. South cook islands and Papua New Gunea on 20. trying make it into Philippines, there is a fb group for 11 meter dx in phils and only few active ops. going be a challenge

31 volt filaments X4 simple math says wire in series. Use by pass caps and I would use a fuse in line just for filaments. that is just a rough answer and by no means a step by step how to do.

awesome contacts,, only thing I hear on east coast in evening time is aussie and south American stations

Few of us get on ch28 AM in morning time, drinking coffee and telling lies as old men do. Band was quiet and then out of no where unit 4209 mobile London England broke the ch looking for DX. Said made his day to make it to USA on AM. didn't hear any other skip, then few minutes later 317 out...

I have built and used the Christman forced current feed method of phasing on 40 meter verticals , worked well.

as for small VSWR issue,, put an antenna tuner/coupler inline at the shack and tune vswrs down. no need climb into the attic anymore,,search zep and extended zepp,, the longer the wire the more gain you get in certain directions. instead of using coax use ladderline to feed the attic dipole...

two pieces of 3/4 emt conduit less than $10 cut to length and have a vertical dipole OPTIMIZED for frequency of design. direct feed no matching network loss

Put a Mark 3 in front of it and piss off everybody in 20 mile radius with the PING on key up.:cool:

Angles vary,,its the nulls you need to worry about. When the angle of radiation is understood about the antenna you install. Then you can control the lobes of the radiation pattern. Yagi vs dipole. Of course the yagi has more gain but in real world testing switching back and forth between a...

small antenna,,build it in the living room XYL will not mind:whistle::whistle::whistle::whistle:

Welcome,,ROBB posted it few years back, he is one of the admin type guys here

If the amp is a tube type amp then the amplifier also needs to be tuned. Radio>>>> VSWR meter>>>> amplifier>>>> watt meter>>> dummy load or antenna Turn amp on and tune it as it should be tuned, dip plate tune the load !!!! now that the amp is tuned with no modulation,,cw , fm mode,\ or am...

I have one..been using it for years,,works ok and does what it is designed to do. I especially like the attenuation it allows you to really align the receive sensitivity. there are better options available now but for what it is it works fine.

Maybe it is a bilingual transmitter?? Sawtooth an TR?

I am wanting to purchase both meters for an Amp supply LK500 amplifier. If any one has any in the junk box or a parts donor rig I appreciate it Band switch too if it is serviceable thanks Ken
