475Re: Kantronics, Kam XL
- Oct 8, 2006Hi guys, sorry it's been a while since I checked this group.
Here's a bit of an update.
From what I have heard the mode works fine. The only reason it doesn't
have better support (YET) is that there are no simple hardware
platforms available for it. This is why I was hoping to see Kantronics
include the mode in their Kam XL. After all the XL bosts DSP
technology and is the only TNC I know of currently on the market
It is disapointing to say the least that years later nothing has been
done to offer more modern DSP modes in this TNC, after all it is it's
main claim to fame. Flash upgradable with the latest modes etc etc.
Currently I receive no replies from Kantronics when emailing them
about this. It has been over a year now since they first started
development on the mode for their TNC.
My current info from the grape vine is that they don't have a lot of
interest in supporting the Amateur market for their product as money
is more forthcomming from the commercial sector.
This in it's self is very sad and bad news for us.
So what does the future hold?
I myself am currently looking at using USB sound card dongles chained
off a dedicated PC. Power usage is of course going to be horrific and
exactly the path I didn't want to go down as it will exclude such
setups on hilltops etc where power is usually provided by solar
panels. But what can you do. A TNC solution at present is going no where.
Long term, there is no reason why a developers group couldn't look at
a alternative open source image for the Kam XL. While Kantronics do
not seem interested in making their code open source. I can't see any
reason why if a group started from scratch on their own version an
alternative could be developed that supports not only Q15X25 packet
but all the other packet modes and speeds currently so sadly missing
from the XL. This sort of thing has been done for everything from the
TinyTrack to DVD recorders. Where the original designers have let the
consumer down, people have picked up the torch and turned a great yet
lacking device into a killer product by getting together with other
like minded users and writing their own firmware.
So if anyone is interested in this and has programming ability. Please
contact me vk4akp@... and perhaps we can start a developers
group to do just this.
In the mean time all my Kam XL's will go back into moth balls and I
guess I will start to go down the USB sound card trail.
Keep in mind that until a newer mode is invented, other then 1200 baud
PSK, Q15X25 is currently the only other option available to anyone
wanting to run packet on HF at a higher baudrate then the traditional
300 Baud. I have also heard of people running G3RUH at 4800 baud on
21Mhz. But once again, I don't know of any current TNC technology
available to do this.
As I've pointed out to Kantronics, what they really need is for the
packet mode to be an independant setting to the baud rate. That way
the device is far more flexable for things like HF and Satelite work.
Once again, I won't hold my breath.
Anyhow, I'd be interested to hear who's QRV in this mode and on what
frequencies etc currently.
