Hi Gang...

.....Just had to tell you about a simple QSO that I had on 40 meters last night... Central Bahamas to New York with 2 watts!!! No big deal... But wait, there's more...

.....Mike - W3IRZ kitted a limited number of transmitter kits for the North Georgia QRP Club called the "NoGa Twin Tube 80"... I was very fortunate to be able to get one... Mike was only able to make a few kits because most of the parts came out of peoples junque boxes, you see, this is a two tube 2 Watt transmitter... It uses a 12V wallwart for the filaments, and rectifies and filters the 115 VAC house voltage to come up with 150 VDC for the B+... Mike says just about any audio or transmitting pentode will work with perhaps a few small parts adjustments... My rig uses two "Mighty 6AR5" firebottles in parallel to deliver appx. 2 Watts to the antenna... A simple mod to the coil turned my rig into a two-bander on 80/40... I built it on a small cedar box that some Alaskan smoked salmon came in... Mike's original version was built in an Altoids tin with the power supply in a separate plastic container... This kind of project lends itself to creative packaging... I spent a couple of very happy days putting this little jewel together, and it has rekindled my glowbug juices...

.....This is fun !!! If it sounds half as nice on the receive end as it does in my monitor receiver, I am pleased... Now to put that 80/40 regen receiver together... Where's my kerosene lamp ??? I will be on most evenings between 9PM and 11PM eastern time zone... My main operating frequencies will be 7.040 or 7.050 and 3.579...

.....Mike has been kind enough to let me reproduce this circuit on my webpage so others might enjoy this rig... I will also put up the circuit for his nifty 12V two tube regen receiver that might make a good mate... I have not built the receiver yet but once parts arrive on the mailboat, I will be giving it a try... If you have any leanings toward "Hollow State", this is fun !!! Just remember, that you will be dealing with possibly "LETHAL VOLTAGES" !!! If you have not worked with high voltage circuits , find an Elmer who has to show you the safe ways to work with this type of project !!!

.....Take care and have fun... Keep-em-Glowing...
