Subject: FT470 mods

To: info-hams


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

de Peter G6ZYT.
