I recently began wearing hearing aids myself, so I know what you're going
through. You have to remove hearing aids to use conventional headphones, or
else you get audio feedback screeching. When you remove hearing aids, if you're
like most people, you lose ability to hear higher frequencies, whi
Since it's not in the instructions, you should leave the speaker
disconnected. Seems clear. RX audio is a secondary feature in a
transceiver.
Sometimes, obvious steps are left off from kit instructions. This is
usualy an oversight. The kit builder still needs to use some
judgment.

The weather has been quite changeable this week. High temperatures in

It is only a quick guess, but I would think you might want to check the

While operating RTTY, in order to prevent amplitude variations caused by
static crashes, I like to turn off the AGC. It always worked with my Icom

limited FM signal to my Hal DXP-38.

A hollow conductor is not analogous to a coaxial cable. It has no

The KPA500 does *not* forward serial data thru from the RS-232 (PC) to the
RS-232 (XCVR) connector.
The KPA500's back-panel XCVR RS-232 connector is used for those transceivers
(primarily Kenwood) that provide band data through a serial connection, if

That is correct as far as changing between 115 and 220VAC mains goes, but

If the pipe is OPEN at its ends, would not the current flowing on the

You may be misreading something. The ONLY true receive-only antenna is
available with the KXV3 opt
When you change the fuses, you insert the fuse holder so 220 is visible in a
little window instead of 115. That changes the wiring to the power
transformer input for 220 volt mains operation. It's described at the
beginning of the Owner's manual.

Am I correct in assuming that in order to run the KPA-500 on 220 volts
all that is needed is to change the fuses to the provided 6 amps, wire
the correct plug on the power cord and the power supply will adjust
accordingly?
Thanks,

It is used for trade show demos where we do not have the mains power available
to run the amp at full power. Turning it on disables the RF output, but still
simulates it on the Watmeter.
