Start with 1 Watt, then go with 2 Watts, etc.  If you die, back down a Watt (hi).

The supports are driveway markers and I really lucked out at a Flea Market with the $4.00 heavy duty tri-pod.  I have attached a picture of the assembled unit if anyone is interested I have more and some additional hints and details to offer.

As for use with a pacemaker ?  You will know if it is bothering you or anyone else I believe.  When I tune up I am listening (RX) or using my Sark 100 so there’s no large amount of RF present....... Operating (TX) one would be several feet away so at 5w I doubt that you would be affected but just go at it slow (1-2w) and see what happens.

Anybody have some decent designs - I do not want to design it myself. I'm not too proud to borrow someone else's work. 

Also, does anyone know about any problems with a transmitting mag loop and a pacemaker (QRP levels only).

Prior to the start of the 40m net, WNØWWY was heard with 579.  Also N4MJ with whom I had short exchange was 579.  WB1GYZ exchanged briefly with WNØWWY.  I could hear WB!GYZ's signal but it was not readable here, being only 100 miles distant.

On 80m The QNI procedure was pretty ragged and things sounded like a QRM fest for much of he time.  N4HAY was 589 here (note his correct call sign).

Johnny,

I got in late after our Card night (9:15 EST), nothing heard on 40m, waited for the 80m and only barely heard a few dits and dahs..... some day it will be easy again...... right ?

OK.  I do have a 20 and a 40.  Hope you someday offer a 30 meter version.  This is a really nice radio.  My friend, Curt,  KB5JO,  uses his 40 meter version all the time.

A very good  explanation in my opinion
Starts with a very simple crystal set and ends with a very nice regenerative set !
These are very nicely explained and with the fact that a  regenerative set can also transmit
Quite a bit of very good basic info here !
I find most everything easier if I start at the transmit
