I have only used it on 20 m so far. I hope it is stable on the other bands as well.flathagenhttps://www.blogger.com/profile/11155798668216436343noreply@blogger.comtag:blogger.com,1999:blog-973137714505742515.post-63008745331835630112016-10-16T05:47:19.241+02:002016-10-16T05:47:19.241+02:00LB0MG, Nice adaptation of the HF amplifier.

I recall the gain and stability were very sensitive to the IRF510 source lead inductance. Very pleased to learn your amplifier build met your needs and you enjoy using it.<br /><br />73,<br />Mike, WA2EBY<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-973137714505742515.post-13549250435770839982016-06-21T19:18:56.448+02:002016-06-21T19:18:56.448+02:00Actually, the pads are MeSquares.

It has brought to 100 DXCC worked on JT65/JT9, but not quite 100 confirmed yet.<br /><br />73<br />LA3ZA<br />http://la3za.blogspot.noSverre Holmhttps://www.blogger.com/profile/08306221557326542499noreply@blogger.comtag:blogger.com,1999:blog-973137714505742515.post-37767156723636132142016-06-19T11:49:02.722+02:002016-06-19T11:49:02.722+02:00Hi.

Even if the distance was only 20 km, it was a historic event for LB0MG being the first ever LA QSO :-) I was running about 8 Watts. During this initial testing I also reached Brazil at 11000 km.<br /><br />73, LB0MGflathagenhttps://www.blogger.com/profile/11155798668216436343noreply@blogger.comtag:blogger.com,1999:blog-973137714505742515.post-2439210683236061352016-06-19T08:32:46.630+02:002016-06-19T08:32:46.630+02:00Nice!
