My ride to work this morning on the north slope of Alaska... but too windy today, blowing snow has reduced vis too much. Waiting out the storm.

Took this photo about 20 years ago of a Motorola Quarter Kilowatt VHF RF Power Amplifier I modified, took out the small conduction cool tubes and replaced with two 3CX1500A7 tubes, that baby would put out so much power I was hearing echo's off the moon using it, really:

KL7FB 144 MHz 5 KW Power Amplifier


Tell me that was echoes from the moon with a Yagi and not a dipole or vertical. That's insane!

A live oak I planted in my yard not long after moving in. For a slow grower, it still grows quite a bit each year.

Taking apart an old HPS ballast today. Is there anything dangerous in here I should watch out for? Trying to avoid shocks

Melles Griot head lasing a little bit. Unfortunately the Vanadate on both units is cracked, I'll need to find a replacement. Both KTPs + Pumps are still good though, perhaps not quite up to factory spec, but still useful. Will probably use them as parts or find a way to stick a larger piece of coated Vanadate in there.
