Greetings all,
The original purpose of the UK Foundation licence 'approved
kit' rule was to limit the likelihood of a M3 (ie
Foundation) amateur transmitting out of band either by
excessive tuning range or excessive spurious. However the
merit of allowing transmission with home-brew equipment was
recognised. CE legislation made definition difficult, as
already observed, kits were exempt from needing a CE mark.
Early BR68/F documents simply said "approved commercial
kit".
Even a ready built commercial offering could transmit "out
of band" since, then 28MHz was out of band for Foundation.
However the display clearly indicated that as well as the
band edges of the other bands in a way that a kit might
not, especially if using an analogue display. The onus
always ultimately was on the person pressing the ptt and
the aim was to give that person fair (and accurate) display
of what they were doing.
Now, 28MHz is permitted and dealers may modify old or
commercial PMR equipment and give the M3 a letter-headed
report of compliance to IR2028. Actually the IR does limit
the transmitter. If it is able to transmit outside the
specified bands then it is not 2028 compliant (unless it is
very very clear to the operator that he/she is about to do
that). Ooops I didn't know that is not a defence.
