I have a couple of questions for the group. First, does anyone know if the
AEA PK-12 can be used as for tracking as can the KPC-3 with the 6.0
firmware??
Secondly, I have a newer DELL laptop that I would like to use for APRS.
Hard as I try, I cannot get my KPC3 to work on the Com Port. I have a
cable that adapts from serial to USB. Tried that but it does not see the
TNC at all. Has anyone figured out how to make a tnc talk to a USB port?
I got my Garmin to work on the serial port, and if I want to add the tnc I
will need another port anyway.
Thanks

Yes, the PK-12 can be used as a tracker. I was not able to get mine to work
until I upgraded the firmware from 7.0 to 7.1. It's been several years
since I did it so I'd probably have to learn how all over.

Als far as I know PLC is only a replacement for the local-loop, so only
short-distant. The local-loop is one of the most cumbersome and expensive
parts of any network. The alternatives like internet via cable-TV, ADSL and
the combination of telephone uplinks with sattellite downlinks all solve
the same problem. Making local-loop connection costs about $600.- for each
subscriber so it realy saves a lot of money if existing cables van be used.
It doesn't make sense to use PLC outside the local loop since then you need
enough bandwith to accomodate all the users and its often much simpler to
use the exisiting broadband technology.
Several trail projects with PLC in Europe already failed because of the
unacceptable high level of spurious RF. The PLC equipment has to conform to
the same EMC regulations as any other device or network and currently they
have a hard time to meet that. Maybe in the future when using lower energy
levels it is possible. They have to compete with cable-TV and ADSL
providers so competition is tough.
I'm just thinking, it looks a bit off-topic on this forum, doesn't it?
Let's focus again on tactical wireless connections using radio's (i.e. APRS
and OpenTrac)!
Kind regards,
Henk.

In reply to Bob Bs post concerning web pages for kids I must say he is right
on! I'm working with 4th graders who are just enthralled with CW and love
searching out the APRS activities on maps. I hope someone steps up and
creates the pages Bob has suggested.
Kernan Magnet School Amateur Radio Club KC2AXZ loves both activities.

Well, that's what waivers are for. And, as often is is the case in the
U.S., enough pressure, false information, and funding dollars from the
industry can make regulatory obstructions disappear.

Which begs the question; why did you post your message? :) However, I
don't think we should loose focus on the PLC/BPL threat. You may not
experience the threat as much anymore in the Netherlands, but it is very
very real here. We're talking 2 MHz up to 80 MHz, with all the APRS and
Beaconet activity in between.

My experience was, the road noise was so bad with a 49 mhz intercom that
above about 30 mph it was useless. I looked up some aviation noise
cancelling mike techniques, and here's a thumbnail sketch of what's needed:
First, the overall sound pressure level seen by the electret elements must
be reduced. An unprotected electret is driven into saturation, causing new
harmonics and noise of its own.
Second, it takes two mike elements with acoustical pre-attenuation, one
pointed towards your mouth, the other away from it, wired so common mode
signals will cancel.
Finally, you almost have to "eat the mike" so your speech has a sound
pressure level much greater than the road noise (and all of it attenuated
before it reaches the actual elements), followed by further electrical
attenuation of the output of the entire "package".
I'm still experimenting, and don't have a good mike setup yet.
There's a few other articles that suggest putting an electret element at
the end of some vinyl tubing that is open right next to your lips, to make
the pickup very directional.
Any URLs anyone can post on experiments others have already done and
results observed would of course be very helpful for everyone trying to run
voice mobile from a bike.
