Bert WF7I Finishes BITX, WORKS ITALY

 

That, my friends, is the look of exhausted contentment that comes after you have FINALLY gotten your new homebrew rig to work, and were rewarded by crossing the mighty Atlantic on your first call.    Congrats Bert!   Details here:

Confucian Wisdom from VU2BK in Hyderabad

I'm not a big collector of QSL cards, but this one has been kicking around in boxes and on various hamshack walls for more than 20 years.  I like the bit of Confucian wisdom that arrived in Santo Domingo all the way from Hyderabad.  I was running my trusty HT-37 and Drake 2-B.  Anyone know OM Kab, VU2BK?

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!

F6FEO's BITX 20 (and DSB Rig)

This morning I was looking at F6FEO's wonderful web site (Frank, KM4AXA is building the 28 Mhz DSB rig from Michel's site) .  The drawings have a nice JF1OZL feel to them.

Check out Michel's site.  Just hit the translate button if you have trouble with the French language:

Merci Michel!

MOXON Antenna Project -- Need Rotator Advice

 

 

I've been put together a fishing pole MOXON antenna for 17 meters.  It will be used with my 5 Watt BITX rig.  I need something to spin it around.   I know that many of the cheap TV rotators don't hold up very well.  I had one die quickly out in the Azores.  There seems to be several brands out there, but the rotators and the control boxes look suspiciously similar. 

 

Is there any brand out there that is more robust and reliable than rest? 

I came up with a pretty cool way of affixing the corners of the antenna elements to the fishing poles.  That coil-like thing is the wire part of a bungee cord.  It fits nicely into the end of the fiberglass pole. You have to be sure to get the pole length and the element dimensions properly proportioned, with a sufficient amount of bend in the poles.

Fireballs Emitting RF at HF!

Yea, and that damn gamma ray bust static has been totally messing up the 12 meter band! Someone should complain to the FCC!
