WINLINK and N1URO AXMAIL illegal for UK Radio Amateurs to use these services over Wireless (Radio)..
When G4APL applied for Winlink GB7CIP licence Notice of Variations in November 2014.

Paul enquired about running a HF Winlink system using PACTOR.
He was informed that Ofcom advise that it is illegal for UK Radio Amateurs.
UK Radio Amateurs are only allowed to communicate via
DEDICATED Radio Amateur to Radio Amateur communication systems.

Winlink Global Radio E-mail system is handling third party traffic, which is not permitted under ITU regulations.

As Winlink and N1URO AXMAIL are NOT dedicated, as they allow communication to and from
Non Radio Amateur Emails communications via the Internet.
i.e. General public, companies.
Applies to 3rd party messages and one to one messages.

Seems strange that Paul has monitored other G stations running Winlink send and receive 'emails' from Winlink gateways on the LF and HF bands!

inking East Surrey, West Sussex, London, and Home Counties.

Since 2000,  we have lost nearly all our  VHF/UHF Radio link partners. Due to the remote end partners circumstances changing.
i.e. House moves, becoming Silent Keys (SK). HIgh rental cost of remote aerial mast space.
Lost of interest due to no local activity in their area.
