You are correct with this. The key to prepping is nobody knows your prepping.
Hey Mad, you added "SDR for PC/Linux/Android for comms" to the list. Are you familiar with this? Would like to know more.
I have 3 SDR dongles at current
2 of these https://www.amazon.com/RTL-SDR-Blog-RTL ... 168&sr=8-3
and 1 of these https://www.amazon.com/NooElec-NESDR-SM ... 168&sr=8-6
On windows my software of preference is SDR#, I can tune into fequencies within the dongles frequency range of 500kHz -1.7 GHz VHF/UHF. broadcast radio, Ham radio, some Law enforcement that still use the bands, NOAA radio stations. I use dump 1090 and virtual radar to track aircraft positions. WxtoImg with a virtual cable to download NOAA/GOES images.
On my old potato Acer 7720 laptop that had Vista on it I use SDR Trunk running Ubuntu 18.04 (?). I maxed memory to 4gb and stuck a 125gb SSD for about $60. It decodes non-encrypted APCO digital phase I & II law enforcement. It requires some java compiling that wasnt too bad for me, and I personally loathe java.
For android I use SDR touch out of the Play store with an OTG/power combo cable. Its not as featured as PC/Linux software but you can save frequencies and listen in the 500kHz-1.7GHz range.
The NESDR has an always on bias-tee to power a Low Noise Amplifier that I use with a broadscast FM block. Thats the one I use for satellites. The RTL-SDR dongles have a bias Tee that have to be turned on manually with a batch file, though SDR# may have an option in the settings now. Im still running the older version with a scan plugin to listen to 3 LEO and 2 Fire/Rescue channels in the 500 MHz range that are within the 2.4 MHz bandwidth though I can set it up different. Im also lookimg to setup OP25 on a Pi if I can get it to work on the linux box for the phase I/II digital stuff. The windows route is the easiest and SDR-Trunk does work on it but still requires a lil java compiling.Any more questions let me know and Ill leave specific links to whatever platform you wanna try with.
Edit.. I use the Radio Reference site and app to find the frequencies of local ham repeaters and Law enforcement. Im not sure what they have across the pond but will look into it.
Edit 2.. Sites that list frequencies across the pond. Im not sure if APCO Phase 1 & 2 police digital radio is used. Its mostly in the 750 and 850 Mhz here in my state.
