Success with my ET-2 --TWO TRANSISTOR RIG

 

In my effort to replicate the ET-1 rig of Glen Yingling W2UW, I had a hard time getting the receiver to work well with the single FET being switched between receiver and transmitter, so I retreated a bit and went with individual FETs for the TX and the RX.  This doubled the transistor count -- to TWO.  So it is an ET-2.

I also boosted the power to 80 milliwatts by putting 12 V on the transmitter.  The receiver was running off the 9V battery you can see in the left in the picture. 

Here is the story of the contact: 

To K4MQG from N2CQR:

Gary: Wow thanks for the QSO today.  I was using 80 mW transmitter that consists of just 8 parts!  The receiver was a regen using one single transistor.  So one transistor on transmit and one transistor on receive.  And it reached South Carolina.

I was about to give up hope.  I had been calling CQ for days.  Then I was talking to Rob VE4GV on 20SSB.  Rob suggested that I "spot myself" on one of the DX clusters.  So I did (see below).  Obviously you saw my spot and a minute or so later, SUCCESS!   I'm really pleased.

Attached is a picture of the rig.  The transmitter is around the crystal and the blue pot on the right.  The headphones are from WWII.  The receiver was powered by the 9V battery.  The regen uses a variometer given to me by a friend in the Dominican Republic in 1992.  The main tuning dial is connected to the cap by an adapter from a 1930s-era regen.  Antenna was a 40 meter dipole at about 25 feet.  Obviously your 3 elements a 115 feet were doing the heavy lifting.

Thanks again Gary!

And thanks to Rob for the suggestion on the spotting.
