-------------
1240-1300 TX & RX...and...220-225 MHz TX & RX  
   Print  
I have been reviewing the ft-470's capabilities for some time now, and was just 
wondering if anyone out there in rf land has done two neat mods that i have 
here! we all know that by removing r69 and jumppering it, you will be able to 
tx & rx from 140-174 mhz! well, further reviewing made me quite curious!

There are two more mods that you can do with only two (2) micro dip switches, 
which will give you: 1240-1300 tx & rx...and...220-225 mhz tx & rx! gee, that 
is two more ham bands, and with the aid of the dip switches, we have a total of 
4 ham bands! this idea is not mine in it's entirety, it has been here for some 
time, but with only two dip switches it is a welcome treat indeed! for the vhf 
side of things:

Remember r69 that you removed and jumpered? well, if you remove r68 and and a 
dip, when you engage the switch it will give you 1240-1300 mhz tx & rx! you 
see, it actully takes two switches, one for r69 and one for r68. Well, r69 is 
already done so don't worry about it! and when you disengage it, it will 
perform as normaly as it did before!

UHF side of things:

If your rig already can tx from 430-450 mhz, you are half done! when this mode 
was performed, you removed and jumperedr72, right? now, all you have to do is 
remove and jumper r71, which will coexist with r72, and get 220-225 mhz tx & 
rx! gee, that was neat huh!?
Of course, you did use a dip switch for r71, right!?
I recieved the mods from my local bbs, and at the moment can not remember who 
gave all this neat info, but there is sure a lot of it! i figured that if you 
are boared of a certain band, You could change it! i have not done this yet, 
and am wondering if anyone out there has, and what type of sucess he/she had! 
what kind of tuning was necessary,(if any!) output power, you know, the rundown 
bit! well, hope this helps, and again, hats off to all those who contrib uted!
