Well I  hate to disagree slightly with you both :-) but there's what the
manual  says and then there's the radios themselves.

I'm sitting here looking  at three radios - two are marked "HF Receiver PRS
2280" on the front panel  and one of these is marked "PRS 2280 HF Receiver"
on the rear cover.   The second has the rear cover missing.  The third radio
is marked "HF  Receiver PRS 2282A" on the front panel and again "PRS 2280 HF
Receiver" on  the rear cover.

All receivers have the normal front panel - tuning  knob, displays, lots of
buttons etc but the 2282A has the digital BFO, a  full set of 6 filters,
rather than 4 or 5 in the 2280s, and the addition of  FM mode. Looking at the
back panel at least 1 of the modules in the 2282A  has different output
connectors compared to the 2280.  It's a bit hard  to read the module
designations themselves as Plessey wrote them on to the  labels by hand and
the ink tends to fade after a while.

Based on  this, it looks like the series is the 2280 but there seems to be an
actual  2280 receiver, with a proper front panel and a 2282A receiver with a
proper  front panel and some extra features.  It's a mystery why this does
not  appear to be the case according to the manual.

Hi John
 
Feel free to disagree, it wouldn't be the first time I was wrong :-), but  
the manual is consistent on this throughout, it's not just in the model  table, 
and I don't think what you've pointed out is inconsistent with my  previous 
comments. 
Later the manual goes into more detailed descriptions of the  three models, 
2281, 2282, and 2283, never a mention of an actual 2280  receiver, whilst 
specifically stating that "the 2280 series comprises three  basic versions, the 
2281, 2282, and 2283". 
 
I was aware of the later 2282 having some different rear  connectors, 
although wasn't aware of the digital BFO, and didn't realise it had  become a 2282A, 
but still don't believe there was ever an  original "2280" that wasn't either 
a 2281, 2282, or 2283.
 
In essence, all sets were 2280s and the model numbers were more a  Plessey 
"in house" way of distinguishing the variants, which in the case of  the 
original 2281 and 2282 was only the front panel, so I suppose they  considered that 
to be pretty obvious in itself.
 
However, since all sets were originally just marked as 2280 it does make  
sense to me that the later 2282A was marked as such in order to distinguish it  
from the earlier version.
Whether or not there was a corresponding 2281A I don't know.
 
I don't think there's really a significant right or wrong on this,  I've 
always considered the set as the 2280 anyway and don't see any reason  to change 
that, but was just agreeing with Michael's answer to Dave's  question, 
forgetting the 2282A for the moment, as to whether the 2280 and  2282 with full front 
panels were different receivers, and the answer is  still "no".:-)
