My FT-847 does not transmit on 70 MHz. It is a 0M serial, which should place it at November 2000.
After looking at a detailed photo that I took this morning with the bottom cover removed, it appears to be un-modded.?
I did a bit of digging on the Internet and it looks like Keith G4FUF is the master of this particular mod. From his writeup (??) it does not look
really worth it, at least I am not willing to tackle it. If I weigh the risk versus the reward, I don't think there is enough activity here in the NorthEast to justify modding my radio. Then I would need a whole new set of antennas...
