Hi All
Has anyone got the online_kiss app to work with a kpc-9612 plus?
I have changed the init txt to intface kiss and reset
I have tried putting the tnc into kiss mode before the app starts
I have tried different port speeds matching my tnc setup
And nothing ever shows up, but...
using some other programs I see data coming from the sat on this tnc.
I would like to get this working to make use of the write to file feature.

Hello,
I have a ST2 interface, and am wondering if anyone else is using a
non-Yaesu rotator? I have a Yaesu G500a for elevation, and a
CDE/Hygain Ham II for azimuth. This setup worked well with my Kansas
City Tracker board, and the Yaesu G500a part of the system works PERFECT.
The trouble is, no matter what software I use, or even if I manually
issue pointing commands via serial terminal, the ST2 will stop my
rotator too early, resulting in offpointing by about 20 degrees. I am
using the same voltage divider that I used on my KCT, so the ST2 is
seeing a 0-5v reading from the azimuth rotor POT. The LCD display
matches the analog display within a degree, so the ST2 knows correctly
where the azimuth rotator is aimed.
My PC is communicating with the ST2 perfectly, I can see the display
on the LCD of where the rotator should stop (say 300 degrees) but it
will actually stop at 280 or 320 for example. Unlike my KCT, the ST2
will only make one attempt to aim. The KCT would stop the rotation,
let the rotators and antennas settle for a second, then fine tune
again if neccessary.
I believe that this can be resolved by changing the sample rate or
something else very minor. I've found the source code, and even tried
twice to contact the author. I guess that because I didn't buy his LVB
Tracker, he refuses to answer my emails? Not everyone has a pile of extra
money
laying around to donate to Amsat. I've donated in the past (back when the
economy was
in much better shape), but I cannot afford to right now, so I bought the
Foxdelta ST-2 rather
than the "genuine" LVB Tracker.
I have tried many nights to compile the source, even without making
any changes. MPLAB says I need a C compiler, etc, and I've tried
everything I can think of to add one.
I even bought an extra PIC for testing, etc, and put the .09 firmware
on it, so now I have two PICs, one with 0.7 and one with 0.9. Both
versions do the very same thing.
Can anyone help? I'd like to be able to release a new version of the
HEX file for the next guy in this situation. I really don't think it's
necessary for me to sell my Ham II and buy a Yaesu rotator for this to
work.
73 and thanks for any suggestions.

Hello Kyle.
Have you tried talking to Foxdelta themselves?
Sadly, Foxdelta chose to take the LVB Tracker and make it their own without
the decency of asking either AMSAT or me first, and therefore AMSAT does not
benefit one iota from that.
I donated the IP for the LVB Tracker to AMSAT some years ago. Indeed, if you
really want to save money, you are welecome purchase the parts yourself and
build it up the information has always been in the public domain. However it
was never intended for a third party such as Foxdelta to pinch the IP for
their own personal or commercial gain.
The 0.9 firmware is on my website together with a programming tool, you do
not need any Microchip development tools. That firmware has been working for
many years now in certainly hundreds if not thousands of LVB Trackers.
However I don't think that's your problem. Much more likely is that you have
a grounding problem. There needs to be a _very_ low impedance ground return
from the rotator to the PIC's ground or else the ADC will provide erroneous
values. Typically this should be the screen of the cable.
If you're sure it's my firmware doesn't work with your Foxdelta hardware,
again I really do suggest that you should be discussing that with Foxdelta.
73, Howard G6LVB

Unless we want lightning fast antenna rotation, we're going to need some
sort of gearbox with virtually any motor we're likely to find. We could
gear the drive to a simpler pot as well.
Gus, I used a pulse width modulator to slow my DC motor down with out
having to loose a lot of power. This eliminated the resistor and the motor
ran cooler. Mine cost $80.00 usd out of Canada but I understand that they
are nothing more then modified fluorescent light dimmers.
My thought would be to count the pulses instead of a pot. I think we will
be stuck with gear motors if the goal is to go small and have lots of
torque.
Even with the PWM mine was a gear motor but it beats a big restive load
hands down.
I would like to move away from stops and find another way to establish
0~360az and 0~90/180ex indication so as to enable continuous rotation to do
continuous sky scan or search and rescue with out having to wind up and
damage my coax. I am not sure what battle ship radar uses for constant
rotation but that would be the ticket.

Hello Nadar, Ken, and Kevin.
If you cold send me a text file of your settings, I could take a look to
see what is happening.
There is a command that you need to set from 'newbie' mode to 'expert'
for the KPC-9612 to accept and keep the settings that you change. I am
not near my KPC-9612 manual, so I can not give you the exact command to
check to make sure.
Email direct please.

I've been working on a packet setup for ISS and other satellites. During

What's the appropriate way to contact others via ISS?
I'm using a Kam Plus, are there certain settings I should be using or

I've looked at a number of websites and they seem to differ in the

Hello Howard,
Thanks for the reply. I have posted on the FoxDelta email group, but
haven't
received a reply. I should mention that I don't think that the ST-2 is
malfunctioning, nor do I think that your code has a problem. I just have a
different type of rotator than the typical Yaesu. It would certainly make
things easier if I did, but it would be quite an ordeal to change the
rotator in my situation.
I did not know the background of the Foxdelta vs. the LVB. I do understand
that Amsat gets a donation with every LVB, and my intention was / is to
donate again to Amsat when I can.
I can certainly see where you're coming from re: the IP. I guess if nothing
else, the ham satellite community as a whole benefits from your public
domain IP, which helps generate more interest in satellites and satellite
operation.
As far as the hardware and software goes, I'll look at the grounding, but I
am thinking that the issue lies in the fact that CDE uses a 12 volt
feedback
POT.. I built a simple resistor voltage divider back when I first got my
Kansas City Tracker, so that the KCT would see 0-5v instead. This approach
gives the KCT (or LVB) the correct voltage range, but I believe it may
lower
the resolution of the feedback system?
I'll also try some ferrites on the leads from the CDE rotator box, in case
transients are to blame.
I'm certainly no programmer, but the software seems to stop the rotator
immediately when the ADC sample value equals the target azimuth value. Once
the antennas stop moving, the final location is different by 20 degrees or
so. Once the rotator stops moving, however, the software doesn't recheck
to
see if the rotator is actually where it needs to be.
My idea was to either change the ADC sample rate, or perhaps add a pause
after the rotator stops, and repeat the routine to "fine tune" position.
This is why I have been trying to recompile your source.. I've already got
PICs programmed with your 0.7 and 0.9 HEX files..
73, many thanks.
