1 OHM is fine, a link and 1 Ohm in this instance is the same thing, probably work fine up to 470 ohm?

No, does not have 4 meter mod.

The resistors on the board don’t seem to be 0 ohm, they’re 1 ohm. ?Have others found this? ?All documentation I can find says it doesn’t matter.?

Avoid Transmitting 30 to 40 MHz as the HF low pass filter will heat up and burn at 100 Watts

Does your Japan Model have the 4M UK Mod or not?

Also try 111010.?
It seems there are different configurations , and possibly conflicting evidence.?
I doubt if Yaesu would make a custom IC, just for JA market

(after setting jumpers:

On the jumpers try 101011 by jumper number, do? reset after.?
Should give HF coverage, 144-148 and 430 -450

Hi FT-847 fans!!

This is Carl, KO4SSA.
I just purchased a used 847 on eBay, from Japan.? I’m wondering how to modify for US bands.? As delivered only TX 144-146 and 430-440.
I’ve searched high and low on the the web, including Colin, G1IVG’s page, and emailed him!!? Haven’t heard back.??

I’ve tried several solder joint configurations and will not TX on 146.52 or 445000. About to give up.? Is the Japan stuff transmit range burned into EPROM or something????

Colin lists several HF coverage configurations and I am able to transmit on 14.550!!? (into dummy load of course)? I point out as evidence that changing the solder jumpers did do SOMETHING.? Also, initially the cross-band repeater item was not available on the menu and now it appeared.? More evidence that changing the jumpers did something.

Thanks Carl
