[Elecraft] [K3] : KRX3 live

[Raymond METZGER]

Hi Mike and Elecrafters,

I started assembling the KRX3 yesterday at 2 p.m. and switched the K3 on at
9 p.m. after having also installed additional crystal filters
(Better to do it at the same time rather than disassembling the rig once
again).

I'm impressed by those who got it in less than three hours !

Although my K3 is # 615, I had to solder the additional resistor in parallel
with R91 (My RF board is Rev A). W4 was a soldered jumper, not easily
accessible, even after taking the KBPF3 board away. But the most unfriendly
step was the last one, plugging the KRX3 module into the sub-in and sub-out
connectors and managing the TMP coax. Plugging the Front panel into the main
board was for me much easier than when assembling the K3 (experience curve
impact, probably)

When you switch your rig on and nothing works, don't panic and take a breath
: if the main receiver is dumb, it's because the RF gain pot has been
inadvertently turned fully counterclockwise during the surgery, if the
sub-receiver is dumb, it's because some parameters have not been properly
set (crystal filter in my case), and if you get an ERR PL2 message, it's
because you need first to upgrade the software and secondly to make a
synthesizer calibration !  Finally my KRX3 is working FB and there was no
problem with the assembling !
