: Is APRS runnng on HF? Last I used it, it was only operating on VHF. Doug, k3qt Tune your HF receiver to 10.151 LSB and listen to the APRS network on HF. It's at the very top of the 30 meter band. The two tone modulation on LSB puts it a hairs width inside the ham band. 30 meters works great 24/7 most of the time. |

I'll check it out. I had very good luck with the position locator
in Winlink while cruising. Family and friends got a real kick out of knowing where we were. Doug, k3qt "Larry W4CSC" wrote in message ...

The entire setup consists of a radio, TNC, GPS, and a computer.

: Larry, what else do you need to transmit or receive the position reports on 10.151? A computer and packet TNC (terminal node controller), which is like a special modem for packet HF radio. To operate on HF, you'd need a TNC made for HF, not VHF. On VHF we operate 1200 baud with wide shift. On HF, we are limited to 300 baud and very narrow shift. The Kantronics KAM '98 is such a modem: http://www.kantronics.com/kam98.htm It is made to directly connect to your NMEA 0183 GPS and will beacon APRS over your HF ham SSB radio. It operates many modes: GTOR™ PACTOR AMTOR ARQ, FEC, SELFEC, CCIR 476 & 625 PACKET 300, 1200 or 9600 bps RTTY NAVTEX / AMTEX ASCII WEFAX EMWIN HF e-mail CW GPS NMEA-0183 compatible TELEMETRY REMOTE CONTROL REMOTE SYSOP ACCESS HOST Mode KISS many useful for boaters, like NAVTEX, WEFAX, PACTOR, and AMTOR which is called SITOR on the marine bands. HF email is also included. When plugged into the computer, the computer runs a terminal program made to command the KAM which automates its use. If you plan on leaving it to automate HF email delivery to its built-in email box, get the 512K Memory expansion for it. It'll run fine just connected directly to your 12V house batteries. It draws little power, around 150 ma. Of course....you'll need a GENERAL CLASS HAM LICENSE to use it. This isn't an emergency comm. |

I have a KAM+ I'm willing to part with. The only thing I've ever used it
for is APRS. Doug "Larry W4CSC" wrote in message ... Wayne.B wrote in : Larry, what else do you need to transmit or receive the position reports on 10.151?

Several more questions: Is the Kantronics TNC comparable to something like the SCS PTC-IIpro which is the recommended unit for SailMail? How would you automate sending a new position packet every hour or so? Is there any acknowledgement that your position report was correctly received? Can a position report be sent to APRS via EMAIL? |

They have alot of the same features except for the one you really need for SailMail. That being Pactor II and Pactor III modes. The SCS TNCs are the only ones to offer it because it is proprietary. How would you automate sending a new position packet every hour or so? The TNC does that for you. At least my KAM Plus does. Is there any acknowledgement that your position report was correctly received? I'm not sure, but I don;t think so. The position reporting used by Winlink is though. I don;t beleive SailMail has any position reporting feature but I haven't used SailMail for a couple of years. Can a position report be sent to APRS via EMAIL? Not as far as I know, but check their website for lots of details. www.aprs.org Doug, k3qt s/v Callista |

Doug, you might have given the impression SailMail requires
Pactor II. According to their primer http://www.sailmail.com/smprimer.htm...of%20Equipment SailMail Primer SailMail will work with Pactor I (a la Kam+) albeit at slower speed.
