I just received mine. It was ordered nov 27th and arrived today in CA. I never received anything other than an email receipt too. With Xmas mailings going on give it 3 wks then contact them if needed. Mike KF6KXG

Then, last week, we applied the same technique to the RF deck, with excellent results. In a 20-minute brick-on-key test on 40 meters, the fans cycled between speeds 2 and 3. Previously it had been speeds 4 and 5. I feel that these changes, which required ordering some different components, are well worth the trouble.

I?m a QRP guy at heart, but even I have to admit that hitting the key at 1500 W is a bit of a rush, especially on an amp that keys silently, like our smaller radios. And thanks to the latest changes, hunt-and-pounce ops, like me, will almost never hear a fan come on.
