A Different Kind of Workshop



Sometimes it is good to take a break from the electronics and look at how people are making other things.  I've been working on the heat sink for a 140 watt solid state amplifier, so this fellow's comments about working with metal kind of resonated with me.

BITX 5 Watter Makes the Trip to Tokyo

The solar flux index was only 151 this morning, but grey line conditions to Japan were very good.  Yoshi, JA1OJJ, was booming in on 17 meters.   We had a nice chat.  He said I was 55.  His 5 element quad helped a lot!

Wow.  Looks like something Peter Parker would really like.  This one was sent to me by Stephen, G7VFY.  It comes from Japan:

Santa Arrives at SolderSmoke HQ! Rigol and Black&Decker


Santa Claus obviously heard my distress call when the TEK 465 gave up the ghost.  This morning it was replaced by a RIGOL digital scope.   I'm going through the tutorials.  Wow, lots of features.  A Black&Decker jig saw also arrived -- this will help in my cabinetry efforts. 

Last night just before dinner I talked to Kiyo, JH1MDJ, in Tokyo on 17 meter SSB with the 5 watt BITX.   I kind of broke through a small pile-up and we then had one of those "please repeat your power level... I can't believe that is 5 watts to a dipole" conversations.  

Happy Holidays to all!

Now That's A Radio Shack! JH0JDV


I was at the workbench this morning, working on a 30 meter DC/DSB transceiver.  I had the Barebones superhet tuned to white noise on 17 meters.  Then I heard a strong CQ that sounded like DX.  It was Ely, JH0JDV.   He was the only signal on the band.  We had a very nice contact, no problems at all.  I was running my normal 10 watts to a dipole.  Afterwards I Googled him.  Wow, he has a REAL radio shack!  FB Ely!
