I just got an old HR2510 and was thinking of doing some up grades and am considering adding a Chip Switch.Has anyone done this mod to a 2510 and did it turn out ok?
The installation wont be very hard to do and is well within my abilities to complete.Just looking for some user feedback from others.
Tnx Bob VE1CZ/CEF451

If you doing it your self make sure you have a good soldering station. I used a desoldering station and was able to save the uniden chip.
May need to realign after.

i've done it more then a few times. earliest 2510's were fairly easy. next batch had some nasty epoxy over the factory chip. that stuff is a real pain to dig through. paint stripper & tons of patience! of course the 3rd & 4th versions 2510 came with a non-modifiable chip & REQUIRED either the early chip, or a chipswitch-once you get through the epoxy. same for the 2600, not modifiable without a chip change. anyway, once you CAN unsolder the chip-if it's a NOT MODIFIABLE version- i just cut it & remove 64 individual pins. i HAVE unsoldered & reused early chip, yes that was time consuming....just needs to be resoldered, no socket there! older chipswitch required additional kit for 12 meters, new one doesn't. they also require programming. some radios turn on & are 'there', others require internal 'registering' & 'setup', programming done from external controls. i've been ready to take a sledgehammer to some only to let it be til the next weekend & things just seem to 'work'. there are other mods that go hand-in-hand with the chipswitch-open the clarifier & put it on a switch, rcv mods, agc mods, broadband mods, AM & SSB xmit mods, power mods, there are enough mods to spend WEEKS on one of these! use a well grounded soldering station-static electricity can supposedly destroy the chipswitch before install is complete if you're not careful. some mods are noticeable to the user only, others will get compliments from those you speak to. is it worth it? sure is if you have time, patience & ability!!
