[amsat-bb] Icon ID-51A for satellite

[Pavel Milanes (CO7WT)]

Hi Oliver.

This problem with the baofeng affect us only on the case you have a 2m 
uplink; if you have the case you may want to put a duplexer (or a LPF 
for 290Mhz) on the TRANSMIT radio in the side of 2m as close to the 
radio as possible, this will considerably attenuate the 3rd harmonic on 
70cm.
