A friend has loaned me a Kantronics KPC-3+ TNC with v9.1 firmware. I've been searching for settings specific to this unit for ARISS work. Most of what I found are generic settings (some info is conflicting).
I'm wondering if anyone is successfully using one of these units for ARISS work, and, if so, what settings do you use or recommend?
Thanks,
Hi Kelley,
... searching for settings specific to this unit for ARISS work
I'm not familiar with the Kantronics syntax for typing commands but see below for a general summary of the parameters you may find useful.
ARISS has a summary of hardware TNC and soundcard TNC operations posted at: http://www.ariss.org/uploads/1/9/6/8/19681527/k9jkm_2012_symposium_ver 2.pdf (careful, might line wrap this URL)
The list of parameters you will find useful but may need to adapt to Kantronics syntax:
MYCALL - Your Callsign Default is NOCALL, but you want others to know you are there.
DAYTIME - YYMMDDHHMM Used if you want to timestamp the packets you are receiving.
MONITOR ON - Displays all packets on the frequency
MALL ON - Displays all packets on the frequency (connected or unconnected)
MCOM ON - Displays the AX.25 protocol with the message (might clutter your screen)
MCON ON - Allow you to see all packets even when in CONVERS mode
MSTAMP ON - Monitored packets are timestamped
MRPT ON - Displays the entire digipeat path for the packets.
CONSTAMP ON - Connect and disconnect status messages are timestamped
HEADERLN ON - Header information is displayed on separate line from message text
PASSALL ON - TNC will accept and display packets that have errors (noise). Partial packets, even with errors, are often still readable to the human eye.
PASSALL OFF - TNC will only accept and display packets that have complete CRC.
CONVERS <enter> - Mode to type packet message from keyboard directly to the TNC. Ctrl-C will exit CONVERS mode.
MHEARD <enter> - Displays your TNC's "heard" list (updated only when PASSALL OFF)
UNPROTO CQ VIA ARISS - Most basic string for ARISS to copy, route, and digipeat your packet

You can configure AGWPE for the KAM TNC and make sure to provide the commands in AGWPE to initialize in the KISS mode then use UISS to communicate with the ISS.
IniKiss1: XKCH OFF IniKiss2: INTFACE KISS IniKiss3: RESET
ExitKiss On Exit Checked
I have read XKCH OFF and INTFACE KISS sometime's is not recognized by KAM, I use ^M with MFJ 1278B and it works.

Thanks everyone for all your suggestions.
I've been testing the unit on the APRS frequency of 144.390 MHz while playing with the various settings suggested. I am not using host mode (KISS). I have the KPC-3+ (version 9.1 firmware) connected to my Icom IC-746 via the accessory ports on the rear of the radio. The radio provides a unsquelched constant audio output. With this setup, I am free to play with the volume control on the front as it has no impact on the output to the TNC.
Having said all that, here is my problem. With the volume turned up, I can hear the packets the radio is receiving. I can see the Rcv LED light up on the TNC. However, I do not see most of the packets I hear displayed in the software (Teraterm, Winpac, UI-View, etc.).
Before changing the settings, I used the restore command to set the TNC to factory defaults. I have configured the TNC with all the settings suggested below. I also have passall set to on. I see about 1 in 10 packets displayed. When listening to ARISS, I see even less. I assume that with the current settings, I should see even the bad packets displayed. Perhaps my assumption is incorrect.
Have I missed a setting? Perhaps the audio level from the accessory port on my IC-746 isn't at a high enough level? Any assistance would be greatly appreciated.
Thanks,
Kelley
