HISTORY REPEATS ITSELF ?
I have just seen comment and question regarding the anticipated band
extension for Region 2. (?)

" Greetings,
When and if the future extension to the 7MHz band comes in there will be
a lot of transceivers that will not allow transmission outside of
7.00/7.1Mhz.
What will be the solution to that ???? "

He also suggested that some would say that you should buy a new
transceiver.

Or, if the zip on your wallet is stuck, find someone who knows how to mod
the gear you've already got. "

Well, Ian could well say, "I told you so", but, hang on a moment.
Alan also pointed out that someone may come up with a modification to
solve the problem.
I can certainly sympathise with anyone who has a well working piece of
equipment that generally satisfies their needs.
I also would feel for those who cannot always just lash out and be almost
forced to buy something else that they cannot really afford.
It has been my experience over the years, and I believe a fortunate one,
that we have generally within the Amateur Radio ranks, people who will
usually find a way around problems of this nature.
I have encountered many an instance where a piece of equipment made to
cover a particular range of frequencies needs only a minor modification to
extend the range.
Let's face it. In the case of the allocated HF bands most of the major
companies manufacturing Amateur Radio equipment build a basic model to
cover the whole range of such frequencies used within the Amateur Radio
Service on a world-wide basis.
They then provide some simple form of circuitry, or even a means of
programming, so as to restrict the frequency coverage for use in certain
designated areas according to the various local regulations.
Whilst I cannot lay claim to any immediate easy answers regarding
particular types and models, I would be very surprised if this situation
did not usually apply.
I do know of at least two well known models of HF transceivers, with a
general coverage receive capability, where a very simple modification;
(as simple as just cutting a single track on a printed circuit board, or
un-soldering a wire link); allows the equipment to TRANSMIT on frequencies
right throughout the HF spectrum, albeit in some instances with some
slight deterioration of power output levels.
Thus I suggest that one should adopt a "don't despair" attitude, at least
for now, until such time as you find the answer one way or another.
If you search around at this stage for suitable modifications for a
particular item of equipment, you may well find one already described that
you can have at your fingertips to implement when the big day comes.
Regards,
Ian
