Problem getting digipeated via SIS and PSAT

Hi

Names Cris and recently been getting more into saterlites and APRS Via sats.

Have had a bit of success with recieving aprs beacons and even got a couple of messages back form PSAT and an OE station but just can't seem to get digipeats over ISS or PSAT.

Every thing works fine over terrestrial but adding ARISS and other paths just dont seem to work and would appreciate a few pointers.

Using a MK 1 Yaesu VX 8R and Elk antenna.

Been over all the settings and just can't think why I am not being heard.

Any advice appreciated..

Re: VX-8R

Hi Chris

I have no experience of the Yaesu VX-8R but if you have the max 5watts output, GPS turned on and are able to manually beacon local terrestrial aprs then it should work for ISS and PSAT by changing simply the digipeater path only to ARISS and make sure you have that path selected for both ISS and PSAT and you should see you are being digipeated. Then you will need to be heard by an IGATE station to forward it to the internet aprs network to be seen on http://www.ariss.net
Use free version of Orbitron or similar satellite software to see when and where to point the Elk antenna.
Is there anyway you can monitor what you are sending with another aprs radio or software to see what is being transmitted which would help if you still can't digipeated.?

ISS uhf packet digipeater has just been turned on again as it's been off for a few days but is not quite so easy to use as vhf and you will need Doppler correction of +- 10khz around 437.550mhz. Patrick has ISS pre-set memory settings shown here. https://twitter.com/WD9EWK
PSAT (NO-84) is much easier to use on 145.825Mhz and should be able beacon very easy with the Elk antenna. Have just beaconed myself at 2.6-deg over Exeter using Kenwood TH-D74 HT + Arrrow-2 antenna and shows how easily it is to work this satellite at very low elevation.

I had terrible trouble

I had terrible trouble getting digipeated or replied to from ISS until my path included RS0ISS. I do not know why. I am using a Kenwood TH-D72A. My path is now : RS0ISS, ISS, ARISS. Give this a try and see if it works. I am told the ARISS along is enough but I have not had success with that alone - not sure if I have something set wrong in my settings but I did have to put in RS0ISS for it to work.

Hi

Many thanks.

I can see myself being digipeated via terrestrial digipeaters so I know it works but just can't seem to get to PSAT or ISS. I have set memmory channels for UHF ISS as suggested to counter Doppler effect also.

Just can't finger it out. Rx is fine and even seen G7HCE via PSAT... Going over the settings and all looks fine with selection of the path as ARISS or would PSAT work better and would it need an SSID like -1 after ARISS or PSAT?

Home qth is a bit of a hole in the ground for vhf and uhf but even on an overhead pass I struggle.. The only time I did get some success was on a quarter wave wip high on the Berkshire downs walking the dog and got a message back from PSAT and an OE station.

I know the Elk antenna works as I have had FM contacts via SO-50 and the same radio.

Keep trying cifferent things I guess but if there is anyone out there that uses a vs 8r that can confirm settings then please do.

Cheers

Re:Hi

ARISS on it's own is the correct path for both ISS and PSAT, it works fine on my TH-D72 and TH-D74 handies also with UISS with TS-2000.

Do you know someone near you that can monitor your aprs packets to make sure your digi path setting is correct.

Hi I have just digipeated

Hi

I have just digipeated again successfully via a local ground digipeater and seen it reported via aprs.fi so all fine there. Path reported looks like this.
M0KKA-7>5QRYVP via MB7UG*,WIDE1*,WIDE2-1,ARISS,qAR,G0PEB-1

Do you think for sats I should delete the WIDE entries and just leave ARISS ?

Re:Hi I have just digipeated

Hi Cris

If your path is set to ARISS correctly to work both ISS and PSAT you should not get digipeated by local terrestrial ground aprs digipeaters and vice versa if it's set to work local terrestrial ground aprs digipeaters you won't get digipeated by ISS and PSAT.

My digi path is set to ARISS for both ISS and PSAT and this what my TH-D74 sends when manually beacon ISS when monitored with another radio. (ignore the beacon text)

G7HCE-7>UP4RXV,ARISS:`y9&l K\>Around Exeter IO80gr via ISS --- TH-D74^

This is what ISS digipeated today at 09:09 UTC and I-gated by myself G7HCE-6 and shown on http://www.ariss.net

ARISS on it's own is all that's needed to work both ISS and PSAT NO-84 but if you need to add the WIDE in your path it needs to be after ARISS and NOT before ie: ARISS,WIDE1-1

You will need to select between which digi paths you have set in your radio between working apsr satellites or local terrestrial packet as they are both different.

Hi Yes I think for some

Hi
Yes I think for some reason my radio is not selecting just the ARISS path but always adding the WIDE before it even if I select just the ARISS. So I have now deleted the WIDE paths just leaving ARISS. Will try this on the next pass and see. The radio is old and I may have to do a complete cpu reset as it should select the path I set manually.

These things can be a bit trying can't the

Re: Hi Yes I think for some

Hi
Yes looking at your previous post you have added ARISS to the end of the path used for local terrestrial aps packet. Have found digipeater path setting online. No mention if you can add another digi path into memory only changing the default. Follow the procedure shown below to make a new digi path setting and use ARISS on it's own for new digi path and save new setting. With this new path selected you should get digipeated with both ISS and PSAT but not be able to get digipeated on local terrestrial aprs packet. You will need to change this path again as shown below if you want to use local terrestrial aprs packet.

DIGIPEATER PATH SETTING
The VX-8R allows you to set up to eight digipeaters for the APRS Packet Path.
The VX-8R is preset to WIDE1-1 and WIDE2-1 digi-path to insure that your transmitted APRS Beacon is received over wide area. We recommend that you use this setting by default.
1. Press the Menu key several times until the STATION LIST screen appears on the display.
2. Press and hold the Menu key for one second to enter the APRS/GPS Set Mode.
3. Rotate the DIAL knob to select Set Mode Item 15: DIGI PATH.
4. Press the Menu key briefly to enable adjustment of this Set Mode Item.
5. Rotate the DIAL knob to select the Pass Number (1 1 1 1 1 - 8 8 8 8 8 ) you wish to set
6. Press the Mode key briefly to begin callsign entry into the selected path.
7. Rotate the DIAL knob (or press the keyboard) to select the first character of the callsign (with SSID) of the digipeater.
8. Press the Mode key to move to the next character
9. Repeats steps 7 and 8 to program the remainder of the callsign.
10. If you make a mistake, press the Band key to backspace the cursor, then re-enter the correct character.
11. When you have completed your entry, press the PTT switch to save the new setting and exit to STATION LIST screen.

Hi thanks for the research

Hi thanks for the research and info.

I deleted the first two entries for the WIDE paths and replaced it with a single ARISS entry in slot 1 as described in the text. I then tried this on a 70 degree pass this afternoo. No joy on that pass either but I did see your call G7HCE digipeated. I will take the Elk and radio up to the downs tomorrow. Looks to be a good PSAT pass about 14.00. I can be a clear 360 degree un obstructed view of the sky from there. If that does not work then the radio must be at fault but it does digipeat terrestrialy and that just baffles me. I have seen a Video on YouTube of a guy digipeating via the ISS using the same radio on APRS so it has to work some how.

Thanks for all the help.

I see you are now using TH-D72.? I also used this path before to get shown on ariss.net. This should now get you digipeated by ISS now using same path.

Hi

Yes just could not get the Yaesu to work no matter what I tried. Something very odd with the Yaesu and I see through a bit of research that Yaesu don't allow full access to the TNC in their radio's. Still it should have worked but in the end decided it was time for a new HT with full functionality. The d72 worked first time on a low pass and minimal settings.

I picked up a message from you today and sent you one back. Would be interested if you got my message?

Re: Hi Yes just could not get

Sorry did not get your message as the sat was blocked by my house but did see it later under messages on http://www1.findu.com/cgi-bin/pcsat.cgi
It was great to see your call pop up into my station list. Yes the Kenwoods 'like it says on the tin' just works without too much fuss.
I have both the TH-D72 and TH-D74 and with the D74 it shows own callsign in station list as confirmation when digipeated unlike D72. I've been out birdwatching mostly during the days so not been on the sats very much of late.
Hope to catch qso with you soon.

Thanks for the pics. Yaesu

Thanks for the pics. Yaesu just seem to make it a little more difficult. The VX8 works fine terrestrialy but just will not digipeat via a sat!
Birdwatching, well my farther is a very keen bird watcher and has written / colaborated on bird guide's. Now in his mid 80's and just got back from a birding tripe to Gambia.

Re: Thanks for the pics. Yaesu

Hi

I'm sure the Yaesu can be used for the sats. It would need the ARISS in front of the WIDE1-1 statement (ARISS,WIDE1-1) for it to work. Now that you got THD72 you could hook it up to pc using soundmodem and monitor what the digi path the Yaesu is transmitting. For ISS uhf digi you can setup some memory channels using Kenwood's MCP-4A software for split operation as per Patrick https://twitter.com/WD9EWK
Yes bird watching is fascinating and have a few bird illustrators and artist nearby who publish in the the well known books. Gambia is nice place to visit with some exotic birds, another friend of mine went last year.

Hi David

I have tried every combination of path for the yaesu but it just wont play. I am thinking it may be something to do.with not having a built in gps but just a hunch. I could as you say use the D72 to monitor it at some point. Would be nice toget to the bottom of why. I have a reasonable technical understanding having spent 20 + years working in mobile telecoms and done most things amature radio wise in 32 years since I was first licenced. If I remember my final year project at college was to build a RTTY modem and it worked. Still have it in the loft.

Will let you know if I ever do get the yaesu working.

See you on ISS or PSAT.

Re: The THD72 appears to be working

Hi Cris

The THD72 appears to be working for you now. You can also pre-edit User Phrases into memory to use in conjunction with the funtion button to paste messages to a callsign shown in Station List.
I'm just behind you with 28 years in the hobby mostly on the data modes. I use to like the RTTY and Amtor modes when it was popular in it's day as well as conventional packet.
As long as you can manually enter and set your gps/aprs coordinates and and can beacon should be no reason to not get digipeated by ISS and PSAT with the Yaesu. By monitoring your beaconing should help in why you are not getting digipeated as it works for local aprs packet ok.

Hoping to work ISS uhf digipeater again late evenings as it's been on night time passes.

Yep got the GPS coordinates

Yep got the GPS coordinates set manually on the Yaesu but its menu system is very different to the Kenwood. In the Yaesu you have 8 slots to enter the path. When seen on the aprs.fi it shows the path commer seperated with the slots in order 1 to 8 or however many are filled. First 2 have the WIDE in them by default. After that you can enter anything you like but even delleting all entries and just adding ARISS in slot 1 has not got a result. I have tried many combinations in the 8 slots without success. As you know the Kenwood allows you to edit a path as you wish commer seperted and its really clear what path has been set. When I get a moment I will use the D72 to monitor and see what its doing.

Yet to try ISS but do have the 70cm frequencies in the memories with offset for tx / rx as suggested. Will have a look for a path that suits to give it a try. Will be nice when they get it back on 2m and not have to worry about Doppler.

I liked packet as it was and had fun with that. Never really gave aprs a look as couldn't see the point in just sending a position report locally but sms type message and position messages via sats does interest me to combine with my like of walking and wild camping over Dartmoor. Up to now it's been by small cw hf trx's and long wire antennas. Should be down that way again for my summer exploits.

Well done. I didn't make it

Well done. I didn't make it as I have been a little ill this week and not up to the usual service..

Might have worked out the issue with the Yaesu. It's a bit flakey and will only tx with ARISS as the path with the call sign set with no SSID. Even then it seems to not emit a signal even with a full meter deflection and a red tx status light in manual setting.

Used the D72 to monitor it and sure enough the first ID was ARISS..
