This book set is not cheap, I always wanted it, and now suddenly an opportunity came for me to place an order (and possibly have the bill covered for 😃)

The books cover all sorts of transmission and modulation schemes and provides detailed information on them all: application, how they look in time and frequency domain, etc.

If you’re into various sorts of radio monitoring, either professionally or on a hobbyist level, these books are really nice to have around 🙂 They’re not meant to be read from end to end, although you can certainly do so, merely they’re supposed to used as a handy signals-library 😎 📻 📡

In the world of radio monitoring or any kind of signal intelligence, there are two important quotes:

“Each signal is information”
(Roland Proesch)
“Information always adds”
(Robert T. Hill)

À cause de la propagation troposphérique j'ai pu écouter France Info sur 105,2 MHz FM dans ma voiture en Angleterre avec RDS

Because of a #tropo lift , I could listen to France Info on 105,2 Mhz FM from my car in England, with RDS..

I also brought along the Panasonic RF2400-D DSP #receiver with analogue tuning to see how this performed on 648 KHz - although there is some fading (but less QRM from Spain in daytime) the reception is impressive given the distance from the TX - its comparable quality to monitoring Caroline from Caversham in the 80s when they were broadcasting directly from the Ross Revenge (around 10-35kW ERP, it varied over the years depending how much of the equipment was actually working) #radiomonitoring

You can see here why from 1943 to 2018 the #BBC picked #Caversham (on the border of #Reading #Berkshire and South #Oxfordshire) as a good place for #radiomonitoring (it is high up on the Chiltern hills). The signal from Radio Caroline (250 km away at #Orfordness, #Suffolk) just about reaches here by night, and signals from a 500 kW TX which is apparently at Beijing at 8180 km away are quite strong..
