Re: [digitalradio] Re: ALE 141A
Hi Ian nice to see you on here from the left coast :) Question: what are you currently using to run RTTY with your 746pro? If you are running a sound card version of RTTY then all you need would be the appropraite software. Good place to start looking is MultiPSK which is available as a download from http://f6cte.free.fr/index_anglais.htm Be pleased to help you get started ina really interesting side of our hobby John VE5MU - Original Message - From: va7s To: digitalradio@yahoogroups.com Sent: Tuesday, February 27, 2007 9:21 PM Subject: [digitalradio] Re: ALE 141A Hi VA7SW here i see all these posting about the different digital modes and i do not understand what is being talked about i run rtty using a 746pro can someone tell me what i need to use for an interface for this different modes also can soneone point out a webpage that will describe theses digital modes in a beginner format Thanks Ian VA7SW/VE7IRA - In digitalradio@yahoogroups.com, John Bradley [EMAIL PROTECTED] wrote: calling CQ on 7075.5 (+1500) at 0230Z 40 is in good shape John VE5MU -- No virus found in this incoming message.

Greetings Ian. Just to give my 2 cents worth here, its easy to get confused, so I'd stick with info for the most popular one which is PSK31. Here is the eham web site where Hams critique different ham radio stuff. http://www.eham.net/reviews/detail/3498?page=1 Good luck 73's Bill, KB9LAX --- In digitalradio@yahoogroups.com, va7s [EMAIL PROTECTED] wrote: Hi VA7SW here i see all these posting about the different digital modes and i do not understand what is being talked about i run rtty using a 746pro can someone tell me what i need to use for an interface for this different modes also can soneone point out a webpage that will describe theses digital modes in a beginner format Thanks Ian VA7SW/VE7IRA - In digitalradio@yahoogroups.com, John Bradley jbradley@ wrote: calling CQ on 7075.5 (+1500) at 0230Z 40 is in good shape John VE5MU
[digitalradio] Re: Audio Output
This is what I do with my computer/IC-706 setup. Most likely, the sound output from the computer is stereo (I've never seen a mono out on a comp.) but you can use a mono plug and it will send 1 channel to the radio. A 1:1 isolation transformer between the 2 is recommended. I run the audio from the radio to the comp. through the mic. input. n0xmz --- In digitalradio@yahoogroups.com, Walt DuBose [EMAIL PROTECTED] wrote: One of my sound cards has only one output jack and a mic and line input jacks. I would like to use a simple splitter cable on the output, one to the speakers and one to the AF output on the ACC1 plug of my IC-746. Will this likely cause a problem using Fldigi or PSKMail?

Re: [digitalradio] Re: ALE 141A
It should be said that your link was to an HRD review site although there is a PSK31 program included with HRD called PSK31 Deluxe...For PSK31 you will also want to look at Digipan http://www.digipan.net/ or Hamscope http://www.qsl.net/hamscope/HamScope.html since its a little more basic to begin with?...I have run PSK31 for a few years but it takes time to figure out all these new modes...Confusion is normal...Heck I have been a ham for 22 years and never run RTTY...I loved HF packet but the band has been bad and I'm out in Montana and signals haven't been good for some time...I'm getting around to listen to some ALE if I can find it and figure it out...:) Gary n8gsj http://www.qsl.net/ok2pya/digimodes/ http://home.teleport.com/~nb6z/about.htm http://www.ac6v.com/software.htm http://www.dxzone.com/catalog/Manufacturers/Digital_and_Packet_Radio/ On Wed, 28 Feb 2007 05:08:42 - wrliddle [EMAIL PROTECTED] writes: Greetings Ian.

RE: [digitalradio] Re: Audio Output
Yes, that's what I am going to do...and use VOX to start with until I build an optoisolator PTT circuit. Here is a strange unexpected occurrance...I connected the audio output from the IC-746PRO's ACC1 plug to the soundcard line input and when not running Fldigi, I can hear the received audio through the speakers connected to the sound card. If I tunr on monitoring, I can hear my transmit signal. However, when I run Fldigi, I can't hear the Fldigi transmit tones as I do if the receiver is not connected to the line input. Hi Hi. 73 all...

Most likely, the sound output from the computer is stereo (I've never seen a mono out on a comp.) but you can use a mono plug and it will send 1 channel to the radio. I would NOT advise a MONO plug on a line output. It short circuits the right channel to ground (no ring, just tip and sleeve) and I don't know how resistant a line output is to a short circuit (infinite SWR ? 8-) ). Get a STEREO plug and use only tip and sleeve. Is what I use here. I use a MONO plug on the line INPUT. A 1:1 isolation transformer between the 2 is recommended. I run the audio from the radio to the comp. through the mic. input. n0xmz Well, I am using a 10 k ohms to 600 ohms transformer for line output to the mic input, and it works just fine, since it has to attenuate the signals and up to 1 volt from the soundcard will hardly saturate the transformer primary (an old small plate to line transformer for a triode from the junkbox). Most solid state preamps love low input impedances, and will give the best SNR that way. Those are edges to get clean radiated signals and elephant ears. --- In digitalradio@yahoogroups.com mailto:digitalradio%40yahoogroups.com, Walt DuBose [EMAIL PROTECTED] wrote: One of my sound cards has only one output jack and a mic and line input jacks. I would like to use a simple splitter cable on the output, one to the speakers and one to the AF output on the ACC1 plug of my IC-746. I guess not, if it does not become an RFI entry point. It would be a sort fo a Y cable, feeding the speakers with a derivation to the isolation transformer from the left channel (tip and sleeve). I am feeding my speakers from the rear left and right channels. Will this likely cause a problem using Fldigi or PSKMail? I have not used PSKmail. With FLDIGI and GMFSK, my setup works.

will maybe try this another day, with Terry VE5TLW and his steppir antenna and lots of power.

[digitalradio] Icom X3?
All: It looks like the new Icom X3 is intended for the commecial market, but while looking at a photo of the rig, I noticed it has a built-in PSK decoder like the IC7800. Assuming it is a PSK31 decoder, and not some other commercial mode, it seems strange to offer it on a commercial transceiver. See it here: http://www.onjapan.net/2006/hamfair/img_1984.jpg Tony KT2Q
