[Elecraft] Dual -Watch and KRX3A sub-receiver install in a K3s

[john at kk9a.com]

I bought two factory K3S's, to save money one came without the
sub-receiver. I later realized that this was a mistake and added the
KRX3A. Installing it is a time consuming job and does involve removing the
front panel. I am not sure what your concern is, the front panel was easy
to reinstall and everything worked as it should after adding the module.

different frequency on the same band) on my K3s, I need to install the KRX3A
sub-receiver. I have two K3s that I have built, one with the KRX3A and the
second without. I am thinking of upgrading the second one with the
sub-receiver now.

To install a KRX3A in an already built K3s do I need to remove the front
panel? I am hoping that I do not as to reinstall the front panel you have
to be very careful not to bend a pin. I realize that I have to install some
new additional stand-offs on the main RF board. I have reviewed the KRX3A
install instructions and it's a little confusing on the difference in a
older K3 versus a K3s. It appears that you have to take the front panel
totally apart?

Looking forward to see everyone at Dayton (Xenia).
