Hello FT470 owners... I asked a few weeks ago about mods for the
FT470 to make it receive and transmit on additional frequencies.
I own(ed) the European version which caters for 144-146 & 430-440.
It now transmits and receives 140-174 & 430-440, with additional
receive coverage 440-500 MHz! The mod was fiddly as the chip resistors
are the size of a pin head. You'll need a fine tipped soldering iron
and about 2 hours of patience. Here's how I did it...
For 2 metres.. locate R66-69... R69
which are located at 10 O'clock |
to the lithium battery. R68-(lithium
R69 is vertical, R66-68 are R67-(battery
horizontal. R66-(cell
The combination you want is:R66 & R68 = 0; R67 & R69 = 1.
Mine came with R66 & R69 set for Europe so I just moved the resistor from
position R66 to position R67.
For UHF, locate R70-72 to the top left of the ribbon cable. These are
vertical and in the order:
R71 R70 R72
The combination you want is:R71 & R70 & R72 = 0.
Mine came with R71 set for Europe so I just took the resistor out and have
stuck it to the back of the battery (in case I need to convert back).
If anyone disagrees with these mods and think I've done something wrong,
let me know a.s.a.p.
Cheers & 73
