A little bit earlier than Jim's experience, we converted a bunch of Micor
RXs for 220 and found it pretty easy -- I think all we did was snip 1/3 of
the coil off each of the helicals and make a couple of minor adjustments to
the LO chain to get decent injection. I'm sure we did something to the
front end amp, but I don't recall what it was -- I do remember it was
pretty minor, though. Even with that simple mod, the performance was very
good.
The transmit was another matter, though. You could move the exiter to 220
with a bit of work, but the PA transistors had a cutoff at something like
175MHz and there was no way to make them work at 220. I think we used the
exciter coupled with the PA from the old Midland 13-509 in a repeater or
two, but we mainly concentrated on the receiver which performed far better
than any of the ham 220 rigs.

Subject: A heads up on GPS support for the Cybiko

Hi there,
Several folks have asked me about GPS support for the Cybiko, so I
thought maybe a message on here may be in order to give folks who are
interested a heads up. I hope to include GPS support in the next
release. I've written the documentation and an updated website is ready
to go, but I will need some time to make sure it works as advertised.
Especially because I've encountered so many problems with CyOS while
implementing this feature.
You can see the track of my commute this morning generated by my Cybiko
tracker at:
http://www.findu.com/cgi-bin/track1.cgi?call=kr1st-8
As you can see the Cybiko will act as a NMEA tracker.....an intelligent
NMEA tracker. All functions like mapping and messaging will still be
available while in GPS/tracking mode. But be careful when you write
messages, the tiny keys of the Cybiko are even smaller at highway speeds
:) That's why I included the option of pre-defined messages and
pre-defined recipients in previous releases.
Also keep an eye out on QRZ.com. The announcement for this next release
will probably appear there first since many, perhaps most, of the folks
who expressed an interest are not on this list.
Thank you and 73,

I'm struggling with getting the track1 / track2 CGI's to work on findu.
Both http://www.findu.com/cgi-bin/track1.cgi?call=pa3eug-9 and
http://www.findu.com/cgi-bin/track2.cgi?call=pa3eug-9 don't seem to
work. However, Chris KR1ST's tracking URL that he quoted in a previous
post, seemed to show up flawlessly.
Is there anything I do wrong, or should be doing extra to get these to
work?
Thanks,

The first link you provided works fine for me (unless the track shown is
incomplete), but the second doesn't. I get a "page not found" error, so
I assume that track2.cgi doesn't exist.

My brother must be bootlegging my call again. Darn it! :)

Hi Alex
(Not Chris like I seemed to suggest in my previous email--- appologies!)
The page shows, but the maps don't christallize.... An icon with an "X"
is displayed (the one you get when the URL can't be loaded). Your link
worked flawlessly... The second "track2.cgi" is advertized on the CGI
description page at findu, but doesn't seem to exist at all...
I just checked here at work, and also here
http://www.findu.com/cgi-bin/track1.cgi?call=pa3eug-9 doesn't work (no
maps), while http://www.findu.com/cgi-bin/track1.cgi?call=kr1st-1 is
good.
Thanks,

Hello Ramón,
It works using Netscape 4.7 and Netscape 7. However, on Internet
Explorer 6 I get the same results as yours. Not sure why that is.

Hello again,
It has to do with the number of &IC labels sent as parameters to
Mapblast and Vicinity. I just took your -9 track page and reduced the
number of labels and then reloaded the page in IE6 which works just
fine. You can see your track with reduced number of tracking points at:
http://www.kr1st.com/track1.htm
I guess there's a limit to the number of parameters, or length of the
string passed through the HREF label in Internet Explorer. My page
loaded fine for you because there was only a very limited number of
tracking points.
Hope this helps.
73,

It is a unilateral limit Microsoft set on the length of a URL. There is no
official limit, and all other browsers have limits high enough that they do
not come into play with MapBlast (which has a 200 point limit). With IE6,
Microsoft shortened it below the point where it is useful for MapBlast.
Of course they had a good reason, their software is so plagued with
security holes they were seeking to limit the maligancy of exploits by
keeping any code fragments that may get executed short. Everyone else would
simply fix the holes!
