Richard.
Have a look at? for jumper settings. Depending what your band plan is, it is easy to see what the radio will TX from his listing.
You have suggested links fitted at 1,4,5,6 which would limit 2 metres to 144 to 146 Mhz. I? think you need 1,5, 6
The chip resistors are zero ohm, hence the solder
Bill K2WH-> Hi Bill, I only just discovered the inability to enable the Alaska emergency frequency during a complete functionality check of the radio.? I went thru all the settings to see what was & what wasn't working on my radio.? I needed a full picture of what the radio could & couldn't do.? But yeah, I have no need for it.
Andrew-> I'm unsure about actual power out as I have no way of measuring VHF & UHF at the moment.? I've been looking at some cross needle SWR/PWR meters for those bands but haven't made a decision on which one to get.? I did get a neighbour to walk down the street to a park about 200m away with an FRS radio and he reports full quieting on minimum power.
I followed your link and sure enough it's been opened up.? I'm not too impressed, I? actually said "oh, bloody hell" as I specifically asked about this and the seller assured me it was untouched.? Oh well.? I'll be restoring it back to factory original.? Looks like all I have to do is remove the solder-shorts on pads #2 and #3 and put a chip resistor back on pad #6.
I feel like an idiot as I've had the radio this long and never noticed it could go out of band.? Never had a need to so I never tried.? Heh.
Spence M0STO -> I had the same thought about the relays.? I had my ear to the radio case listening for the tell-tale "click" as I tuned up & out of a BPF and into the next one.? I heard none.? That's when I had the thought that i'd need to look in this area.? Ah-ha!? look at that, "420 - 460 MHZ" circled in red on that schematic snapshot.? Dead-on the problem i'm having.? Thank-you for narrowing it down for me.
I do plan to replace the HF BPF diodes with low noise Schottky type as explained here:?

Examining the bottom board, I did see left of X1001 a soldering job that looked non-original and there was still a bit of flux around it.
