https://www.ebay.com/itm/CR-282-Com...998712?hash=item1c74489778:g:m0QAAOSwX9FZHrr7 Long story short, these are garbage. 3 out of 4 could not be netted, and stability was nowhere near the super-drifty 706MKIIG stock crystal at 7ppm. Keep your original crystal. These are trash. The 4th crystal I had 'a guy' do it. Likely he wasn't qualified so he didn't mention it could not be done. Also not helping, a guy on the 5 star comments writes (in a different listing, same seller, same items): https://www.ebay.com/itm/CR-282-Com...6?hash=item2807351906:g:GXAAAOSweW5VcRqs#rwid "Great TCXO for Icom radios, half priced, excellent quality. Identical pinout. Recommended." Um, this is a TCXO? No it IS NOT. A TCXO has a resistive heating element. This is just a similar crystal to the stock one, except it is far worse in ppm than 0.5ppm as the seller claims (worse than 7 which is your stock crystal), and it cannot be 'netted' because it drifts so wildly. It CANNOT be calibrated. These are not only worse than stock, they are complete trash. About the only thing you can say for it is that the pinout IS the same. My guess, it is either 1) a cheap OEM batch of crystals that do not meet specs (rejects) that the guy is selling as good working 0.5ppm crystals (which they are not as tested), 2) they are possibly counterfeit. I had several people asking me earlier about 'Radio Shack TCXOs' with much curiosity. $45 seems like a steal. ICOM wants like $160. The ICOM ones are REAL TCXOs. These only fit the pins of it, they are NOT equivalent items. DO NOT BUY THESE. Will update the progress on returning them, but not hopeful, as we had them several months before sending the rigs off to be properly aligned/calibrated/etc. So not expecting much but a too bad. Its lousy that a seller pulls this 'don't give me a negative at all' since it skews ratings to all 5 stars when many are unhappy. There may be tons of sales, and tons of returns too.
