I have K2/100 #3132 with the 160m, SSB, and DSP modules installed. I am
also using a KAT100. I have had this set up for a couple of years. The
power source is a battery that is being charged as I am operating. My
antenna is a Zirpel (like a Carolina Windom). The KAT100 is able to find
a match on all bands.
On 160m, 80m 40m, 15m, and 10m all is fine (I don't operate that much on
30m, 17m, and 12m). However, on 20m I usually get a "High Cur" warning
when I first operate (CW or SSB) on that band. Then it goes away. All
seems to be operating OK. Sometimes, a bit later when operating on 20m,
I get a "Low Batt" indicator. That too goes away and all seems to still
be operating OK. I have a voltmeter attached to the battery and when the
K2 gives the "Low Batt" warning, the voltmeter says 13.2 volts. I have
not seen any of these symptoms on any other band.
I am using a home brewed battery charger that my elmer made and it keeps
the battery at 13.6V.
The problem typically occurs when operating on 20m after I have turned
on the rig. It rarely happens when the rig is a bit warm. So a warm rig
and the problem usually does not occur could indicate a bad solder
joint? I am not much of an EE so I would appreciate advice on how to
track this one down. The Cal Cur is set to 3.7.
Thanks
73,
