The simple answer John is "Yes". Your KPA1500 cooling fans are running as
intended.

Good Evening,
Propagation was not good. There was a steady roar on both bands
with fast QSB chopping things up. Signal reports varied from ESP to S8,
sometimes from the same op.
Weather conditions were more in line with the date. My forecast has
only a few more days of snow, I think.
To Ed’s point:
“Some states recognize memorandums of personal property as legally binding, but
there are 20 states that don’t categorize them as legitimate legal documents,
including West Virginia, Vermont, Texas, Tennessee, Pennsylvania, Rhode Island,
Ohio, Oklahoma, New Hampshire, North Carol
Related to the thread on helping other hams' families deal with their
stations after they go SK, there is an idea that I think I mentioned on the

that the general subject has come up again. I have to begin but saying

You might contact IOTA Engineering. They don't seem to make exactly what you
want but they do make emergency lighting inverters packaged with batteries.
Perhaps they can sell you the guts of one of these. I know them for their
battery chargers, which are first rate and electrically quiet.

Based on my experience with my KPA500 and an exchange with Jack, W6FB, I
have found no need to run the Fan Speed at any value other than NOR as
defined via the MENU. {See my comments regarding efficiency.}
I'm aware that "others" have measured and tracked and computed results

Is it normal for only the middle fan to run on the KPA1500 in Level 1? expected
all three fans to run, and simply increase speed as needed to efficiently (and
quietly) provide the necessary cooling. All three fans do run in Levels 2-5.
Is this normal?

A year or so ago I embarked on a project to determine the efficiency and
the "sweet spot" operating parameters of my KPA500. I drive my KPA500
with my Elecraft K3S.
Armed with a good 50 ohm dummy load, two watt meters {one on the input
and one on the output}, and my EXCEL spreadsheet, I meas
OK, I'll make it somewhat Elecraft related... For FD this year I will be
using a KX3 in a 1A Battery effort. To power the KX3 and most of the station
equipment, I will be using a solar-charged battery system that is a
permanent part of my home station.
Begin OT:
However, for some of the station
Both 20 meter and 40 meter nets were having difficulty with propagation.
Definitely short skip on 40.
Thanks to those checking in and relay stations.

Jack,
OK, you win.
I went back to fan speed (0) NOR and with FT8 at 400+ watts, the KPA500
is only "doing" 56C max AND fan speed (2) is maxing also at 56C. So,
yes I will run the fan at (0) NOR.
Also, "rest" for NOR is 44C.

Jack,

OK,
I found the error message...
"ER53, High LPA temperature; check LPA heat sink screws: Temperature at
10 watt stage exceeded its limit. This could be caused by the screws on
the bottom cover becoming too lose, by high ambient temperature, or by
excessive key-down time."
It would be NICE
Is there data showing more dissipated heat with lower output in solid state
amplifiers? I have seen similar posts on the SPE Expert list. The following
KPA1500 post shows much lower efficiency with lower power but not more lost
wattage: I am not an RF amp guru, I am just trying to understand this.
Hi Chris,
Does your K2 transmit OK on those bands, i.e. at full power output?
The fact that other bands have normal sensitivity indicates
that the main receiver functional blocks are OK. The bandpass
filters for 20 and 80 meters have only one component in
common, relay K3, but that relay selects
Jack,
Now that you ask.
I have been using the fan at (1) when I run FT8 to "get a head start"
when I do TX. I don't NEED to. I like to see lower TEMP and it does.
I have been known to run 400W on FT8, too (FT8 is low signal mode not
QRP) and I have been trying to get a Dallas station DE on
Hello,
My K2 developed a very weird issue. The sensitivity is very low in 20 and
80m bands. It receives but the S-meter reading is much low compared to
other receivers that I compared. For example, an S9 signal on another good
receiver is barely S1 on K2. Other bands are fine.
Any advice on w
If there was no recent “HI TEMP” fault in the log, then it was not the KPA500
that caused the display on the K4.
In that case, ask the K4 folks what may have happened.
I have never seen a HI TEMP fault with my KPA500s in normal operation, although
I am sure others have.
I have seen it when test

Yesterday I got a fault message on the K4 screen. It disappeared before
I could see it fully, but I did get "tighten heatsink screws". The fan
was working as its speed was speeding up and the KPA500 temp saw about
