Re: [digitalradio] Re: Digital Modes Presentation (Need Help)
From: Miroslav Skoric sko...@ptt.yu Date: Tue, 13 Jan 2009 Time: 07:39:26 PS: Is there available a short audiovisual sequence of an AX.25 packet signals for download? I'd like to present to the conference audience something like packet audio burst being received and have it decoded on the computer screen (or a short keyboard-to-keyboard conversation between tho ham packet users, or so), but in my area there are no reliable correspondents anymore to make a recording of that. Misko, A few years ago I was on vacation in New Zealand, and was asked to give a talk on AX.25 to a local radio club. I didn't have any lecture material or packet equipment with me, so I had to draw simple diagrams during the lecture itself. A few minutes into the lecture I had the idea to get the audience to take part, by pretending to be AX.25 stations. As you know, New Zealand is the land of sheep, and everyone is very familiar with the sound of sheep. So I demonstrated the sound of an AX.25 signal by emitting a long B (representing an AX.25 connect packet), and a short Ba (representing an ack packet). The sounds were not very accurate (!), but they got the idea. Then I invited a couple of people in the audience to do the same. A QSO followed, with the Bs and Bas going backwards and forwards in both directions. Then I got two more people to set up another QSO. Of course, some of the Bs and Bas collided, so this was to opportunity to talk about retries and hidden stations. Then I set up a digipeater, with other people relaying the Bs and Bas, but with the Bs and Bas extended to Bas and Baas because of the additional packet headers.. Then I set up a national 8-digipeater network, so that eventually everyone in the audience was taking part. Complete and utter chaos! But it was great fun, and I do believe the audience actually learnt something! So you don't always need high tech aids when giving lectures. Good luck with yours. -- 73 Ian, G3NRW

[digitalradio] Re: AX.25 modem as an infrastructure?
Hi Misko. I used to play with AX.25 a lot when I was a teenager. You have two major problems when designing the kind of ad hoc network you are proposing: hidden transmitters and protocol overhead. With 1200Bd shared bandwidth you do not have much wiggle room to cope with either of them. With your ad-hoc approach you would either broadcast data to all nodes in the network (APRS approach), or broadcast routing tables (FlexNet approach) or broadcast request to connect (I don't know any such AX.25 system). Would you be more specific about your approach? Into which category it falls? Flexnet was probably the best AX.25 system designed with working auto router, but still it took some time before the routing tables were updated after a station connected / disconnected. And it was using dedicated links between nodes, so there was no hidden transmitter problem. 73, Vojtech OK1IAK

Re: [digitalradio] Re: MFTTY 3.0.143 is out
I understand, Norbert, now. Hthe information I read leads me to believe (and it's stated as such) that the greater frequency of Pilot tones provides an aid to tuning. IMHO, it seems to me that the pause time that you stated is a bit too long to provide benefit. I don't know where I'd pause for an equivalent of 20 characters. Right now, I am seeing a Pilot tone only at the beginning of the CQ in which I included my callsign, City/State and Locator. I think it could be inserted by the operator at the end of each line of CQ for tuning. I also noticed that without looking at the screen, I instantly recognized the signal by WB4MWD by virtue of the inclusion of the Pilot tones. First time I've been able to identify an exotic mode by ear per se, so the tones have an additional value. I think we just need to adopt a reasonable protocol for the tone use and also allow for manual insertion as needed.

I did set the pause time to a value that is equivalent to the transmission time of 4 Words (20 characters) This was done to avoid an un-needed flood of bothering pilots. My question to the group is: In Pratice: Is that pause time and the effective number of pilots sufficent or is there higher or lower occurrence of pilots needed?
Re: [digitalradio] Re: MFTTY 3.0.143 is out
I think we just need to adopt a reasonable protocol for the tone use and also allow for manual insertion as needed. Howard W6IDS Richmond, IN Howard, for manual Pilot insertion, just configure a macro as only Pilot and click that to insert a Pilot whenever you want. What I think FMTTY needs more than anything is the ability to double-click on a callsign and use it for the macros, such as CALL (for the other station's callsign). I cannot seem to get the TxMacro boxes to work. When I configure a macro with Box1 and put a callsign in for Box 1, I still get Box1 transmitting instead of the callsign. The macros also need to be linked to function keys for ease of keyboarding use. There really is not enough time to fill in the TxMacro box for every QSO. You have to capture a callsign as quickly as possible in order to keep from losing a contact. A double-click has proven to be the fastest way to do that. For example, the significant default DigiPan macros which many are familiar with are: F2 CQ F3 Call 3 (transmit, 3x3, 3x3, 3x3, receive) F4 Call (transmit, 1x1) F5 BTU (1x1, receive) F6 Signoff (73, 1x1, SK, receive) This way, the new user only has to press F2 to call CQ, F3 to answer a CQ, and then just alternate between F4 and F5 for the QSO. When finished, he just goes to the next function key in line to signoff. Of course preferences of others may vary! 73, Skip KH6TY

Re: [digitalradio] Re: MFTTY 3.0.143 is out
Hey, Skip! Long time no. Yes, I think you're touching on some things that could go well toward enhancing the operation. I, too, am having a little difficulty with the TX Macro box as well. However, I suspect that if we keep the cards 'n letters coming in, there'll be some attention given to the ideas for sure. HI had not thought about using a marco for the Pilot thingie. DUH! I've been trying it by manually typing it in. I wasn't thinking macro in that instance. Trying to capture the callsign, QTH, etc does take time and causes dead time too, not to mention creating a cumbersome process. But, then again, this is new as we are awareand interesting. So far, I'm one up on the receiver side. Still working to get my first transmit check out moment.

Re: [digitalradio] Re: MFTTY 3.0.143 is out
Thanks Seigfried! That works now. I could not find where that was in the Help. Now, if Norbert can only code a double-click to enter the call in Box2, that would be great. I know that it is possible under VB6 as I always code it that way in my own VB PSK31 programs. For example, I code according to the following double-click rules (double-clicking in Windows usually automatically selects a word, as I remember.): 1. If the word contains three consecutive numbers, it goes into the RST field. 2. If the word contains one or two numbers, it goes into the callsign field. 3. If the word has no numbers, it goes into the operator name field. 4. For QTH, I select all the words and use a right-click context menu to enter the text into the QTH field. I do not attempt to distinguish between something like PSK31 and a callsign, but rely on the human brain to make the distinction by where the operator makes the double-click selection. 73, Skip KH6TY - Original Message - From: Siegfried Jackstien siegfried.jackst...@freenet.de To: digitalradio@yahoogroups.com Sent: Tuesday, January 13, 2009 12:07 PM Subject: Re: [digitalradio] Re: MFTTY 3.0.143 is out the macro-name for box1 is Name ... for box2 it is Call that should solve the problem greetz dg9bfc - Original Message - From: kh6ty To: digitalradio@yahoogroups.com Sent: Tuesday, January 13, 2009 5:05 PM Subject: Re: [digitalradio] Re: MFTTY 3.0.143 is out I think we just need to adopt a reasonable protocol for the tone use and also allow for manual insertion as needed.
