FT-1000MP Keying Improvement (Excerpt from Inrad Web Page)
The MP keying rise time is 2.4 mS and fall time is 1.0 mS. The fall time
is responsible for the somewhat wide signal, which the MP generates on
CW. There are two points in the radio which can be used to improve the
keying by slowing the voltage change over from receive to transmit and
back.
Three parts are added to the radio. Two go on the IF board and one goes
on the RF board. They are small leaded parts which solder on the bottom
side of the boards. Board drawings are supplied which show the part
locations. The IF board is fairly easy to get at. The RF board is buried
under the final amplifier and is somewhat difficult to get at. Estimated
time to install is 1 hour.
