Another idea is join skcc. They have a lot of ears, many that monitor their chat page. Several BJ ops and many with homebuilding interest. 73 curt

Mike Each time we increase power 4X the impact is roughly 1 S unit at the receive end. So going up to 10w is a pretty small change. Also, to drive a typical 10w RF amp you will likely need to modify t

Here in the East by mid afternoon 40m has been rather long, could only reach paths more than 500 miles. Here i have a little kd1jv paraset qrp rig but its on 80m. Nice antenna setup glad to got somewh

Glad 3 out of 4 of us got involved thus far. Nice idea to make at least some of the presentations available, even if for a small time window. Hans usually will make his presentation at FDIM available

It was much easier for an out of region stranger to mingle in chat text and a maybe a couple vocalizations during break discussion, than it was attending 3 or 4 live events when they were here. I was

Griff I don't recall if this uses a ne602 aka sa612 IC mixer? If so try web search for SA612 10m or 10m direct conversion receiver to get ideas. Check kc9on store to see if he sells 10m crystals. Or m

A frequency display is typically connected to the oscillator buffer by a very small capacitor, 1 or 2 pF. There should be plenty of examples around. Its same strategy as using a freq mite. Curt

Wey Since this thing is used with a transmit crystal, that we spot the receiver to, I don't get the value of a digital dial on a parameter style rig. But if you must, check qrpguys or far east sources

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
