Date: 6 Sep 90 12:47:28 GMT From: (Pete Swynford) 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.
