It's FM in that band, but that's good if that could be added, instead of WFM, as in my country they use FM for mil-air in UHF. When they have joint operations with other countries they switch to use AM.I hope that the EU version will cover also 138-144MHz - this is the VHF military AIR band in Europe.
Hopefully AR7400 would be using narrow tracking filters and they really should add a seperate connector for UHF.
Using a SDR dongle and software I can search the whole 118-137MHz range in 2 seconds, including locked out frequencies for spurios signals and interferencies that slows it down. So probably around 1 sec if the receiver has a "clean" RF reception. Plugins like Omnirig can control a "real" receiver and set it to a frequency when the dongle finds an active frequency for better receive quality. 3-4 dongles and 3-4 BCT15s would be a great setup so AR7400 needs to beat that in reception performance and not cost more than $600 as it only does analog and only one kind of service, so very limited and specific use. I wouldn't mind if they added the whole frequency range of 25MHz-500MHz with quick band scanning. It's a minimal cost to add filters for those bands and have the VCOs to cover those ranges. Why make it so limited in capabilities when it takes so little ta make it a fully fledged conventional receiver that would attract more people?
