Yaesu FT-857D FT-897D 857 897 Frequency modification expansion

Can you tell me if the auto repeater offset still works after this mod version? I read that this feature was lost after the mod that removed jumpers was done.

Anyone?

Thanks!

For the EU version, you remove JP10002 only. Reset the radio and the new TX range will be:1.800 - 2.000 MHz
3.500 - 4.000
7.000 - 7.500
10.000 - 10.500
14.000 - 14.500
18.000 - 18.500
21.000 - 21.500
24.500 - 25.000
28.000 - 30.000
50.000 - 54.000
137.000 - 164.000
420.000 - 470.000

Sorry, I missed these questions:

Hi..what are the expanded frequencies after conversion??
Regards
Peter

1.8-56 MHz, 137-164 MHz, and 420-470 MHz.

I don't remember, but I double check my radio and post the results.

not for 27MHz?
 
Cracked open my 897D to check this out, and boy are those things tiny!

So to verify with my stupidity, after the mod, the radio should TX on CB frequencies, correct? It seems that way, but I want to double check.

Just for emergency use, but it would be handy to have in the event it was necessary.

It WILL only transmit there in case of an emergency :D

Doesn't work on new FT-857D

Picked up an 857D a week ago. Not sure when it was made, but the shop sells alot of these so it's pretty fresh.

Did this mod with a Circuit Writer pen exactly as in the picture. Same factory jumpers. Verified continuity of my new jumpers. Tried reset by v/m-f-power and home-power.

Nothing, nada, zilch. No effect whatsoever.

I'm going on a vacation and will be far from cell service most of the time. I really want this radio opened up for emergency use.

Anyone have any ideas?

Yaesu hasn't changed this radio, and the mod is the current version. I say try it with a good old fashioned solder and see if you get the right results.
 
Ok, I did the mod and was able to TX on all frequencies that I can RX, except for a few. The only ones I am getting a "TX ERROR" on are the frequencies between 88mhz - 108 mhz. Any suggestions as to my error? Maybe one of my solders was subpar?
