Subject: Re: Yeasu FT-470 Mods...

There was a list of strap changes that alter the frequency
limits.  As you will notice all the mods that open up 440 on a
reasonable basis for receive, nuke 440-450 transmit which is
kind of important...

R71    R70    R72          Rx and TX             Receive only
0      0      0            430 to 440 Mhz        430 to 500 Mhz
0      0      1            430 to 450 Mhz
0      1      0            430 to 440 Mhz
