[AK-VHF] NET: 9 March - 144.200 USB

[Edward R Cole]

The net will begin at 9:30 am on 144.200 USB.
I will be running my four 10-element yagi with my new amplifier.
It is rated for 1500w but I will run it at 600w on SSB.

Last week I ran with fans disabled which appeared to cause shutdown 
of the amplifier.
Tested fine after the net so I conclude the overtemp protection 
kicked in to shut down the B+ to the amp.

I will try running the amp at 600w on SSB this week but with fans 
running* during Tx.  The overtemp ckt will be active in case cooling 
is inadequate (which I do not expect since I ran 1200w using JT65 on 
eme a couple weeks ago; JT65 runs key-down for 55 seconds out of 
every two minutes which is harder duty than SSB).

I have my FT-736R set up with the 150w amp into my vertical antenna 
for quick backup if needed.  No coax changeovers involved.
*Note: fan noise may be present in my mic which I hope will not be 
objectionable.

Hope to see you on the net!
