Good, to a point, but he avoids several issues for example the issue of what an "Address" is..So if at a location that has a postal address, under his description you could use the wrong suffix. The same with his description of what mobile is..Under his description you would operate /M as you are sitting within a vehicle, but if it's within the Courtalage of a property that's wrong..So for example you should not use any suffix when sitting in your own drive in the car or /P when operating portable from within the Courtalage of any other postal address where it would /A.

I was under the impression that the transmitting station no longer needs to state a designation of /P /M /MM etc?

There is no compulsion to use them, however using them incorrectly confuses issues..I live very close to the Norfolk Broads & although some comedians use /MM on the broads as a joke, or just for a bit of fun, some less educated individuals honestly believe they have a right to use /MM inside the low water mark & it's confusing as they should be signing /M...

I thought it was no suffix for at home (qth) and /mobile for in a vehicle and /portable for on foot ?

Walking down the road with a handheld is /M (Some call it pedestrian mobile) From a vehicle in a location that is not part of a postal address /M. Using any radio equipment from a postal address other than QTHR /A & from a temporary location in a non postal address location, such as a field, a hill top, a beach etc etc /P, as long as it's not from a vehicle where the set up is capable of operating mobile..so if the battery is sitting on the ground surface, or the antenna is in a tree or on a mast etc etc, it's portable, if the battery is in the car & the antenna is fitted to the car/boat/bicycle or even fitted in a back pack it's mobile...

Alan as another resident of Norfolk I have also heard day cruisers and holiday makers using the MM suffix which is a bit ott when you're moored at Stalham/Wroxham :biggrin: Suffixes can be a grey area for example if I sat in a layby on the A11 rag chewing am I really mobile as surely the definition of mobile is in a moving conveyance. The mobile suffix is an easy way of ridding yourself of a log.
In reply to JGR as the guy points out the use of the suffix is recommended not compulsory. It is intended to give other stations an idea of your situation but is so open to interpretation that it becomes ridiculous.

I have to say I do think when someone is mobile in the broads area, it would be helpful to know if they are in a car or on a boat, due to the difference in signals that can occur between the road route & river route & the fact that a boat moving at 5mph could be worth chatting to, whilst a car could be out of range in a couple of short overs at 50mph..

Sitting in a layby with a radio would only be /P if for example the antenna was fixed..i.e guyed or erected on a ground stake etc. The definition of mobile includes back pack & hand portable, it's where the radio can be used on the move, unless it is being used within either your own or someone elses postal address.
No logs are needed now portable, at home QTHR or mobile..
