[Elecraft] Upgrading K3 s/n 11xx to operate on the 472KHz

[Don Wilhelm]

Jack,

You will need the new synthesizer - two if you have the KRX3.
You will also need the KBPF3A.  If you already have a KBPF3, there is an 
upgrade kit that you can install - the KBPF3MDKT (see K3 Parts and Mod 
Kits).
You will also need the KXV3 (or KXV3A or KXV3B) option in your K3 
because the antenna must connect to the RX ANT IN or XVTR IN.  Transmit 
is on the KXV3 XVTR OUT jack - you will need an amplifier because the 
output is low level (none sold by Elecraft).

73,
Don W3FPR
