[digitalradio] PSK-xx mods
Wondering if there are any PSK-xx (I have the PSK-20) mods out there. Also, will the radio do anything besides PSK31? I have seen references to it working other digital modes--but the frequency is fixed at or around the PSK31 frequency for 20m (14.070MHz). I ask about mods because I'm wondering if anyone has made adjustments to the rig to increase tuning range, etc. to reach parts of the band typically occupied by other digital modes. Thanks. -john W4PAH

If someone answers, simply have a chat. You decide the content of your net, send a file or canned message if you are so inclined, no requirements You also decide which digital mode to use. Log the call signs and QTH of each station you hear. This will enable you to develop your own database of stations that are in simplex range of your QTH.If you live close enough to an area that is in a different time zone and 8PM comes around more than once, feel free to check-in a second time. Upload your heard list to this email group. Andy K3UK Wondering why everyone is thinking 145.000MHz is a good frequency to use? I an not trying to complain here, but 145.000MHz falls within the 144.900 to 145.100MHz allocated Packet frequencies in most areas. Has anyone gone to there LOCAL Packet coordinators or (i hate to say it) Repeater councils to seek guidence about this? Michigan repeater council usually and has in the past worked with users to find a good place to do something without interfering. Can't say about other states though. In Michigan, 144.900 to 145.100 is set aside for Packet usage along with 144.390 for APRS. I listed other frequencies in some previous posts over the past week that are considered 'gaurded' per the Repeater council here. There are PLENTY of 2m simplex frequencies to choose from for doing this and there was an email this weekend from W8RIT here in Michigan that has been using 145.520 to 'play' with digital modes. I think that is a good idea to do as he is close enough to the Repeater band edges to generate interest if someone scans but still doesn't cause interferance to established users either. There is even was a Simplex net going on up in the thumb area for years that did everything from SSTV to the newest digital mode. Haven't heard from them in a few years though so I don't know the status. Has anyone played with say PSKMail or run something on USB around 144.265 to 144.280MHz? There are probably plenty of people out there that might be interested in trying out a different mode other than FM on the latest combo radio out there that offer from DC to 70cm coverage and usage. I am not suggesting operatings below 144.265 as most Microwave coordination is done at 144.260 and the USB nets that I know of in the Great Lakes states are on around that frequency also. As I stated at the beginning, I am not trying to complain, but there is 'other' 2m simplex frequencies that could be used other than the Packet frequencies unless there is NO Packet activity in your area to justify a concern. I am trying to get some input about this. James W8ISS

Anyone ? Andy. Hello Andy. Finally getting to emails after operating CW sweeps this weekend using MixW. Seemed to work good once I got my old Digipan interface from home. Hated the 'nag' reminders about registering it. Not running on my puters...:) I would have used gMFSK or FLDigi on Linux if I had known that. Andy, chck the emails last week for my email address. I put a lot of the Part 97 rules about Automated and Beacon stations into some postings at the begining of last week. James W8ISS
Re: [digitalradio] November 15th is 2M FM Digital Simplex Night
I thought the same thing. However, in my area there is no packet on that frequency.

[digitalradio] Re: Best use for a off duty transceiver ?
Good day, All. Don't forget: monitor SSTV frequencies and post the pictures on a web site. (Just like the other spotting groups mentioned) If there were a page available for 30m MP73-N SSTV 10.132 MHz, we could support more narrow band SSTV on this frequency. Perhaps I'll do this! :) - Lou, W8LEW --- In digitalradio@yahoogroups.com, Andy obrien k3uka...@... wrote: I am guessing that other than during contests, the average amateur radio transmitter is not being used by it's owner for 8-20 hours per day. That is because the owner is working, sleeping, or doing other things. So, what is the most useful thing we can do with our mostly off duty transceivers (at least the receiver side) ?Here are a few things I know we can do... 1. Nothing, turn it off completely and save electricity (save money, lower your carbon foot print) 2. Scan multiple bands via ALE and report reception automatically to ALE Channel Zero (assist propagation studies) 3. Monitor what ever is received in digital modes and automatically report to PSK Reporter.(assist propagation studies) 4. Passively monitor a frequency via WINMOR and be available in case someone wants to leave you email (assist Emcomm) 5. Passively monitor a frequency via JT65A and report reception data to the JT65A W6CQZ logger (assist propagation studies) 6. Passively monitor a frequency via WSPR and report reception data to the WSPR.net (assist propagation studies) 7. Park on a frequency and serve as a PSKMAIl server , when needed. (assist traveling hams and assist emcomm) 8. Run a packet BBS. (assist traveling hams and assist emcomm) 9. Run Winwarbler in PSK31 mode and callsign, signal quality of PSK stations within your passband. ( (Assist your own propagation studies) 10. Run software that allows remote access to your rig and allow others to use it. (assist others access a rig) 11. Run an APRS station on HF in and allow digipeating. (assist traveling hams and assist emcomm) Any more? Andy K3UK
