Question about ISS config with Kenwood THd72

Hi all
we are trying to set up the config menu in the new kenwood handy and it seems we are getting into trouble.
when on menu PacketPath we´re trying to put RS0ISS-4 and we do it (under "others"), but the kenwood seems not to keep the configuration and goes back to Type: New-N

Any hint?

Anyone here that can provide a proper ISS packet configuration using a THD72?

thanks in advance

Use the [MHz'] Key to Select Packet Path

If you consult your CD-ROM manual (as opposed to the printed manual or the "In-Depth Manual') and look at the section on Programming a Packet Path, it states the following:

"When you press [MHz], the '*' icon appears on the left side of the packet path type, showing the current used information."

So press the [MHz] key when you are looking at the 'Others' configuration screen and a star should appear next to it, indicating that it has been selected.

It is odd that they chose this method of selection in this circumstance when the right rocker switch is generally used for selection. I have a hard time remembering how to do it myself.

Good luck!

Thanks Stewart...
I think it works..
You are so kind...tnx for your help

Path is ???

In your first post you mentioned a path different from what I've been reading it should be. I've seen many say to use "ARISS" for the path, which is generic. You have something different. What did you try and were successful in using? Have you tried "ARISS"? I am able to pick up the digip's, and I did a BCN, but I did not show up on aprsopen or I then realized I should set the path (I had left it as NEW-N and WIDE1-1).

Re: Path is ???


For aprs digi always use ARISS in the unproto path.
This is the standard and people should not chance.

APRS Tracking show all contacts?

I think I did it right, but I didn't see my callsign show up in the APRS Tracking list. ISS just went over (1339z).

I caught a couple APRS packets, but the two different callsigns I caught also do not show up in the APRS Tracking list, though they definitely came thru ISS (the first path is marked RS0ISS). Does the list on this web site show all of them that digip'd thru ISS?

73s again! And thanx!

Ah, worked!

I added a WIDE to my path, so it now is "ARISS,WIDE". On the next pass I successfully saw my packet come back to me from the ISS, and even got a reply from W8KRF-6.

Is the WIDE that I added really not necessary, and the real reason ARISS received my packet this time is I just aimed my antenna better?

How did you do it?

What was your setup? How do you contact ISS? Send a message with RS0ISS-4 as the recipient?

I put ARISS,WIDE in my path. Probably the WIDE is not needed; I havent tried it again without it; yet. And i had 5W output on my Arrow yagi. You also need to watch the doppler. Ive not setup a split; yet. I just setup the uplink and downlink; put the squelch open only on the downlink; and set my step size to 5 khz. Then i handle the doppler with the tune knob. When I want to xmit; i switch to the uplink and do my beacon.

Does that help?

How are you setting up the uplink and downlink? A memory bank and switching between them?

I am new to d72a

I am new to the d72a. Not sure how to do all that right now. Do you have the mcp file? Email to kevin at jonas dot com?

Submitted by KJ0NAS on Sat, 2012-07-14 02:57.

Sorry, no mcp as yet

I'm new to the D72 as well, and haven't done any MCPs yet.

I will make a crossband split in memory (which will make it easier), and program in five of those puppies (make it easier still) and then I will try my hand at the MCP and send it. Maybe it can be posted.

I think this site needs a

I think this site needs a menu option called quick start. It would contain instructions on how to do voice, packets, how to understand the information given on this site. The information is all here but you have to dig around to find it. Just look the RS0ISS-4 and ARISS bit here. There is confusion on how to actually make a contact.

I came to this thread because I also have a D72A and want to try to contact ISS.

With WIDE as the second parameter if I understand path correctly if the ISS repeats your packet back to earth the next digipeater that picks it up will see ARISS*,WIDE. It will see the first path has been used and see that the second path is WIDE, something it can handle. It will repeat it as ARISS*,WIDE* (if set up for the old way of doing a path). Since both paths have been marked as used no more digipeating will happen for that packet. What is your understanding of the path? I will have to see if I can find the website I saw that does a really good job of explaining the path.

Also have TH D72

Hi, I have been using the Kenwood TH D72 for a couple of months now and found that on VHF it works ok, but on UHF, which it is on at the moment, it will give your position report, and it goes onto the APRS map, but no good for digipeating. The reason is that on UHF the doppler shift is so great that it only has a few seconds to receive you then send back to you before shifting out of your passband. On VHF, it stays in your passband much longer. One tip for UHF is to set your beacon to 0.2 minutes, not the default setting. That transmits your beacon every 12 seconds. On VHF it is ok to use 0.5 minutes, which is every 30 seconds. I hope that helps you. (And the TH D72 is VERY capable of APRS via the ISS.) Best 73. Tony, G4CCB.
