The AL-80B is easily keyed directly by the K3. You'll need to build an ALC
interface cable if you use ALC (I don't). Of course, the AL-80B is not a
QSK amp as it normally comes, so you'll need to extend the K3's amp key to
RF out delay to about 15ms to keep from hot-switching the K3 output.
Keying a modern day amp is easy peasy with the K3. I have an AL-82 and it
works great with the K3. Make sure you set the TX depay to about 15 ms as Phil
pointed out. Works great. With the older amps, you might have to make some
sort of interface, but it might not be necessary.

Yep. The broad as a barn door reciever thing was a great feature in those
days since we were crystal controlled transmit and had no idea where on the

I need help picking out a proper dummy load to use for calibrating my new

Jeff, I would consider an ohm meter reading of a non-inductive resistor to be
a better indicator of low SWR than any available SWR meter including the famous

Jeff: It all depends on the power level you want the load to handle. Do
you want to acquire now a dummy load that will handle the output of a KW
amplifier in the future, or just the output of your K3?
If it's just the K3, then the MFJ-260C at $40 or so should be fine for 100W

In the good old days you would just build one. Six 300 ohm 1W resistors in
parallel between a couple of sheets of PC board, tin can lids or whatever, with
a coax connector mounted on one side and the center conductor attached to the
opposite sheet and you're done.

I was looking through the schematic for the KPA100 and it looks like the LP

If so do they provide extra LP filtering on RX?

Yes, the KPA100 low pass filter for the selected band is in the circuit
at all times if the KPA100 is connected to the K2. The KPA100 circuits

ribbon cable (the 12CTRL line).

Ok thanks Don.
BTW, am I correct in observing that only the RF cable to J1, the power cable
to J4, the audio cable and the ribbon cable to the control panel are the
only connections of the KPA100 to the K2? I.e. does the RS-232 interface go
in through the ribbon cable?
Looks like it's an easy
If you have an AM filter, it is easy. Just set you rag chew EQ settings on

Well there isn't, the limit on a Macro is 120 characters. The problem is,
you can't just set an EQ band with a single command. You need to step UP or

For example just to set 50Hz to +12 you would use:

There are no RS-232 signals on the ribbon cable. TXD and RXD are at
CMOS levels through the ribbon cable and the conversion to RS-232 levels
is done on the KPA100 board.
BTW - the AUX I/O connector on the KPA100 (and the KIO2) is just what it
says - it is NOT an RS-232 connector although

You have it right - just plug it in, assuming that the footswitch plug
matches the K3 jack - the headphone/mic connectors will plug right into
