I have 2 Radio Shack PRO-164 made by GRE which perform well on VHF and UHF air. However, they are larger than the BC125AT and similar in size to the PRO-43, also made by GRE. It has full coverage with AM mode on all airbands. I saw one recently on eBay for about $50.
Unfortunately Uniden screwed up on the BC125AT milair coverage. I wish they hadn't. When they were first introduced, I wanted one. Uniden assumed that 380-400 Mhz had been devoted to P25 trunking. This is not the case. Military frequency assignments do not follow band plans This has been discussed a few times on RR. I saw a post from this past week, that someone confirmed the US Air Force F16 demo team operates on 384.55 Mhz.
Given the price and performance reputation of the BC125AT, it is still worthy of consideration. Especially the price. I passed on getting the BC125AT. I didn't want a scanner lacking coverage on milair. I bought the BCD325P2 and it includes 380-400 Mhz and also a very good performer on civil and milair. I also needed a newer P25 scanner for P25 Phase 2. It is the same size and form factor of the BC125AT. I also have the BCT15X and it is the best scanner I have ever had for civil and milair. It too has the complete UHF military band. Great receiver performance and loud clear audio.
There is still a fair amount of AM aircraft transmissions between 380-399.975 Mhz. I monitored a few last summer from Marathon Florida. Also, do not leave out AM aircraft transmissions between 137-143.975 Mhz and 148-150.775 Mhz. The USAF Thunderbirds operate on 140.40 and 141.85 as well as UHF frequencies. All military aircraft frequency assignments are 25kz spacing regardless if VHF or UHF. Although rare, military aircraft may also operate on 116-118 Mhz. The radios will tune there and it does get used. I am aware of this from personal experience with ATC radio on military airfields.
The European and Australian version of the BC125AT has 380-400Mhz, so the missing 380-400 Mhz doesn't seem to be for avoiding some sort of image or intermod issue as suggested in some posts. I investigated buying one of those, but the prices are very high. They had been available on eBay, but looking for them recently I didn't see them.
