Richard:

No. That is correct coal is better, might help a guy keep "getting warm."
grin


And, that current source works, I have used it many times (makes an
excellent test lamp for 5-30V)... will with stand at least 30V+ across drain
and source and maintain ~10ma... when the REV current to its' led drops to
zero, max flows though the FWD--all other cases they must share that 10ma...

Regards,
John

Hi Brett,

I've no doubt, but in your circuits - never. Doesn't make sense
unless you need parts ballast. It's like when the watchmakers
advertised watches with 60 jewels, and there were only half a dozen
points that actually used them.

Richard:

If I use that at QRP levels, then go to QRO, that constant current source
will be used! I have a couple of burnt leds which offer proof... at a KW
the fet would wave bye-bye (even before I suspect)...

Regards,
John

Richard:

I just climbed up and pulled the SWR meter off the pole--DUH!!! Those 50
ohm resistors are actually 1500 ohm 2 watt metal oxide.... sorry, as usual,
your post was relevant.... I just couldn't see it till I opened up the
box....
I could have sworn I stuck 50 ohm ones in there--getting old here... but now
I can see it, if they had been 50 ohm, power to the ant would have been
really limited.... and I would have "smoked" that winding and resistors...

Anyway, will try to get sometime to toy with it tomorrow, and paste the
"real" schematic of it on the webpage....

Warmest regards,
John
