Re: Band Limits - MARS ?

[VTuff59795]

Eric & Wayne,
                        will  there be a 'MARS' type band limit capability
available sometime? It would be  nice to be able to move outside the current
band limits for Air Cadet (similar  to the Civil Air Patrol cadets in the USA)use
here in the UK on our MOD assigned  HF channels!

Hi Vic,

We now have a simple Windows based utility program to unlock TX outside
the U.S. limits for use on U.S. MARS and by those outside of the U.S.  
Run it once and the rig is opened up. (It needs RS-232 / USB
communications to the rig as usual.) It also has a button to re-enable
the U.S. limits.

Note that the final legal responsibility of where they TX is on the
user. (Note: the K3 will still block high power TX  in the CB band..)

We are testing the final version right now. I'll also post to the email
list when its ready.

I just thought, I should have said    'Ask and you shall  receive ... and
transmit'!
 
I had to laugh at that!

Firstly, you ought, if possible, to allow the user more than
unlocking/locking of the US limits. If I take my K3 to a country which
*requires* limits, e.g. in some places 6 meters is not allowed, then it
would be necessary  to limit the K3 accordingly before importing the K3
to such a country.

Secondly, can this easily be ported to MacOs and/or other OSs?

Thirdly, thank you for yet another cool K3 tool... :) :) :)

Hello Eric,

Excellent news on the program to unlock TX. Thank you.

Is the program also able to lock bands? For example, I would like to  
at some stage legally import my K3 into Thailand where 6m is not  
allowed. I would need to disable 6m TX/RX on my K3 before handing the  
radio over to the Thai authorities to check the radio.

There are several open source C and C++ language tool kits out there, e.g,
www.fltk.org, geared towards porting across OSes.  Java's goal of machine
independence makes it trickier to use serial and usb ports in that language, but
there are libraries that allow that as well.  It's important to make this small
but important piece of software available to all customers.

Merry Christmas & 73!

Hi guys,

We have a second program in process that will allow you to set specific
band limits. We have an internal version of that in-house now for use
setting limits for special countries , like Thailand, but it needs some
sprucing up before release to the public.

At this time we're only doing these programs for Windows. We just don't
have the time to do everything for all operating systems. (We not that
big yet! :-) Since these are usually 'one-time run' programs, I think
this is reasonable. If we have time, we may do them for Mac in the future.

Eric,

Great news your having the K3 wide-range TX mechanism implemented!

Do you have any information about the TX frequencies (or ranges of frequencies) supported (or NOT supported, whichever is easier) when operating the transmitter out-of-band?  Even a rough idea would be very helpful.

For instance, your K3 'FAQ' page indicates that the K3 receiver performance will meet the needs of someone involved in MARS extremely well ("There is a small gap at 8.215 MHz").

But, what about 'transmit'?  How 'general' is it's range?
