I am running my K3 off an Astron RS-35M. No load voltage at the rig is 14.0V
(per the K3 display). Running approximately 100W this reading drops to 12.3V.
Is this the norm? BTW current reads just under 18 amps. The amp meter reading
on the Astron is way off.73 Harris K9RJ

Hi,

I don't think that this is normal. It depends upon the voltage drop
on cable between the radio and power supply, as well as any voltage
drop inside of the radio. I actually was measuring this
yesterday. My supply reads between 13.7 and 13.8 on the K3 meter
under receive. With 100W keydown,

I own an Astron analog power supply, and there is NO fluctuation of voltage
under full load, without load, or anything in between. That's what a regulated
power supply is supposed to do. I would say you have a defective power supply.

No, not necessarily.

This is likely due to I squared * R losses in your DC cable; the voltage
is being reduced by the resistance of the cable. I had the same problem.
How long is it? What gauge is it? Are there any fuses or other items
in-line with it?

It only takes about ** a tenth of an ohm ** between K3 and power supply to
drop 1.7 volts at 18 amps. Size of wire, bad crimp in a connector, tiny bit
of corrosion, etc., etc.
AND, the tenth of an ohm may be spread out in different places.

This drop is excessive. With the standard (factory assembled)
K3 power cable, I see 13.9V no load and 13.2V at 20 A with an
Astron RS-35.
I would be concerned ...

I have the computer connected via the RS-232. HRD is working fine so I
don't suspect anything wrong with the connection. When I send a letter

Hi Greg,
Make sure you're not in TX TEST mode, and that the PWR control is set
to the desired level.
If CW Type is using the KY (CW/data keying) ASCII control command,
note that sending a '' character puts the rig into TX TEST, and ''
restores normal TX operation. You can test this using K3

What interface are you using? I tried it with LPT and COM just now, and
both seem to work OK.

Hi Willis,

Hi Dave,
You do present an interesting point on receiver disparity. I think this has
always been an issue, not just due to radios, but also antennas and
propagation. It is an interesting question that will most likely be a factor

can't see the frequency offset on the display while you turn the knob, but it
does change and the display accurately updates when you finish transmitting. I

From the K3 manual:
KEY OUT (RCA/Phono) is the amplifier T-R relay keying output, capable of
keying up to +200VDC @ 5A.
You do not need the buffer for any Ameritron amplifier. In particular the
AL-80 schematic shows the Relay jack connected to the 12V bus.
