Let's see if I mention other kit providers i might get in trouble here, so I will be generic and say there are a few kit providers in US. I remember Doug Hendricks once giving a specific progression f

Clark I recall being way below the lower edge, this is all about being able to cover 120 kHz or so of the band. If you are way below, you have some turns to remove. Also if you are from the original b

Phil These receivers using regeneration have different physics. You should not need more antenna, a loopstick will receive AM stations by itself over hundreds of miles at night. Also better to have le

Suggestions appreciated - some of you have heard my 80 or 160m signal on the verticals - the taller one is still QRV. don't have suitable trees hence these radiators. these things have elevated loadin

If indeed the power cube is linear, and adequate in voltage and current - it can be tamed with a simple regulator circuit. check the QST archives to see if you can find cube tamer article - no worries

I have 2 ground mounted verticals, both happen to be Cushcraft which use a 1.25 inch fiberglass tube. Sometimes a wind gust will bring down the vertical even though have staked guy ropes on each. Or t

Bobby Those were the two xtal sources I was thinking of. I remember only using 2 xtals with my para80set, so 2 may be enough for a novel fun rig. Been a while since I recalled ceramic vxo, yes if a st

Phil Web search led me to pacific antenna, info there. Its a small business, respect they may not work everyday. Curt

Gary Possibly something is amiss in audio stage. Make sure none of the electrlytic caps are backwards. Yes I have built a few regens that initially didn't work, of course it was builder error. Make su

Well when we went to Atlanticon they charged admission but handed or shipped everyone a club kit, taking place of a group build. Instead of shipping door prizes, if the usual merchants offered a modes

Johnny this is a fantastic idea to use technology to gather us together. I watched many of the recorded GQRP presentations - they were indeed presented live -- and a moderator (they may have used a di

Marc Did you try the author, was this w8tee? Was this the rig that used the 49er board from far east? I assume you checked qst archives. Curt

Doc Either will radiate about the same, so it may came down to which is easier to install. The feedpoint of either antenna should be clear of nearby conductive objects of appreciable size. Advantage o

The higher gain should only be appropriate to integrate into rigs that are short in audio gain. I also suggest 0 dB. If you did decide to introduce a speaker, its the matter of having enough power to

Jim well if you study 40m propagation now you may discover the band is quite long at time - so with many stations in 4 state region and about - good to have someone who is not close! wow 'Houston' is

Yeah it would sure freak some out to have 'London' as a YL or a small network on 40m ssb just above there working the BJ stations working split, maybe with a qro cw hanging around if help is needed to

Tim Very unusual for a tuner not to work at all, unless wire is way to short. Check that connections are real with a dvm, once myself I experienced a connector solder joint that wasn't real but open.

Wow, I was thinking I just built the last sw40 ! obviously not ! I did a couple bias resistor mods on the driver to allow running with a little more output, told they came from kd1jv but he may not re

#FORSALE

As it is also nice to encourage homebrew and mods, test equipment is a great idea. I still use the Elsie inductance and capacitance meter, the one that reads in morse, that was kitted by njqrp. Let's

Well the ubitx does this, except lacking a wide IF filter and envelope detector. Funny thing my 12 volt tube regen pulls in distant broadcast band signals (-: How about a 10 or 12m rig, maybe with a v
