What are the limitations of packet-radio in the UK ?
At first packet was illegal in the UK, or maybe it wasn’t. The license did not make this clear. Now it is an established communication mode and recognized by the RA. This means that they have made a few special arrangements if you want to run packet. Firstly you must send a Morse i-dent to give your full station call sign at least every 30 minutes. And you should send a packet i-dent every 15 minutes. Next, you may only pass on mail addressed to a specific amateur station, unless you hold a Notice of Variation to your call sign (designated by a GB7… call sign) – in which case you don’t need to read this section 🙂 .
