I can attest to the fact that a fall from a 55' foot tower hurts like heck.

I can show you the surgery scars to prove it (from 1983).
Lucky I was just a young pup back then or I wouldn't have made it.

Yikes - clearly it should not stay hot in use -- something is amiss.  And the current has to flow from somewhere (the power supply ...). 

Standby for instruction from NM0S (transmitter designer), N5IB and others. 

Okay on refining the pot etc -- all this is part of the building process.  Even the K2 uses a felt washer!

Yes, the BJ still works, in fact worked for a week before I discovered that it was hot.  Touched it while testing for reasons for the drifting problem.  Gets so hot that the middle leg is blue and I had wondered if I had left a soldering iron on while using it out of the case.

Another responder stated that it still gives reverse voltage protection if damaged by reverse voltage.  I had applied reversed voltage a few nights ago or maybe longer and praised the kit designer for protecting old or dumb farts like me.  

The rig still works, drifts intermittently, sometimes faster, sometimes slower.  During my first QSO it didn't drift enough to have to retune though, a nasty thought, because I would probably lose the contact while retuning.  Very touchy.  The shaft of the tuning pot wobbles, more than the shafts of the other supplied pots.  If I attach the tuning knob firmly against the faceplate it is much more stable and easier to tune.  Am going to apply some green felt behind the knob.  Remember that from the early days of radio, to help a knob tune smoothly and not scratch the cabinet?

I had the same issue, IMHO I think there are some mosfet copies floating around that may be of questionable origin. I had some NOS from past projects and replaced mine and tested the reverse protection several times with no failure.

Re: Ocon Oscillator Hunt

Jim, N5IB
 

Just to prime the pump a bit on the huffduff (HF DF) activity at OzarkCon, I've posted in the Files area of this Group a one-page PDF document showing how I cobbled together a small loop on the kitchen counter in about 10 minutes. Note that this is not (yet) a shielded loop.

It has a very sharp resonance that can be found by peaking the noise It does show directivity, but not much on 40 m right now to test with. On 30 m it was clear there was directivity. Being a very small loop it's not very efficient so signals (and external noise) are way down. It was also apparent that the noise at this QTH was directional

Thanks guys, I have fallen off the roof putting up an antenna 7 years ago, broke ribs in 11 places,  punctured my lung and a long recovery… at the time I wished it had been 100 foot for sure!

I have a 1600’ sky loop up 50 foot in my trees….this is a killer antenna on 160 meters and 2.0 SWR or less on all HF bands so tunes well.   I have a 180 acre farm with the perfect tree layout around one of the fields.  I also have a hex beam up about 25 feet.  So I have been active on the HF including 6 meters.  I will check-out the net if not in Church at that time.

    I am guessing Jerico Springs, Mo. is a very good place to live.

    I base that on the fact that I have never heard KY3 TV report any bad news about your town.   Too much bad news from KY3 about other towns surrounding Springfield.

Paul,


I think this may have been the first time I've copied your sig.  I understand that you had had some problems with a new rig, but whatever antenna you're using was doing FB.


I'll be QRV for the Second Sunday Sprint and hope you will be also. 


We're getting a lot of snow today and if it amounts to the 12-15" predicted, then that will blanket my in-ground radials and considerably diminish their effectiveness.  (The purpose of those radials is to harvest the radiation from the adjacent vertical antenna that splashes on the nearby ground and send it back to the antenna's feedpoint for "recycling"; a foot of water-permeated snow is an unwanted rf sponge).
