Today I was thinking about VHF/UHF FM voice repeaters and the trouble repeater owners go to when maintaining a repeater site. Typically the location is a high hill , atop a large tower, lots of hard line, elaborate lightning protection, expensive and fussy duplexers, etc etc. While I am sure it is fun to own such a system, it must occasionally be quite a chore. The chore is sometimes made worse by the fact that repeater sites are often the result of begging cellular tower operators for a bit of room for the hams, then losing the right of access every time the cell site changes ownership (often very frequently). So, in my day-dreaming today, I was thinking that surely modern technology could come up with some innovation that would eliminate the need to secure high sites atop 500 foot towers. I began to think how 2M or 70cm radios could perhaps be re-invented with better (smarter) cross-band or within-band repeat functions. Where , based on some ALE concepts , K3UK calling a local ham on 2M could have the simplex signal picked-up by a station within simplex range and repeated to the desired destination station based on known LQA-type tables . Or, like APRS, some signals are picked up and echoed (repeated) based on number of hops than can be expected between originating and destination station. Maybe QST or CQ calls would get picked and repeated by the equivalent of node stations versus a call between two stations ? Of course mobile operations would pose a more difficult challenge back to the drawing board but this mega station on a hill idea surely has to be reinvented sometime. Andy K3UK

RE: [digitalradio] Re: Individual software programs for various digital modes...
In my view, the SignaLink USB interface is the way to go, both for good operation, and simplicity of installation. Also, I have found AirLink Express to be the most simple program for PSK31 or RTTY…. Even compared to Digipan . Of course one ham’s simplicity may be another ham’s complexity… and personal choices vary widely here on this. Still, I recommend AirLinkExpress be tried first.

[digitalradio] Neby help with digi modes
Welcome to the group. I have a TS2000 and also an SDR-IQ, I will be glad to help in anyway I can. Being an old-time digital mode enthusiast, I tend to suggest that rookies start the way almost all of us did with Digipan. Free, good, and the easiest to set-up. FL-digi and Winwarbler are perhaps the next easiest. You can start receiving digital modes easily by taking the audio out source (headphone or ext speaker jacks) and connecting it via a cable to the line IN of your computer's soundcard. There are some that worry that the audio could be a little to hot and blow your soundcard, I have done it LOTS of times before and never had a problem. To be on the safe side, you can lower the LINE IN audio level in you computers sound card mixer settings. Simply doing the above will allow you to copy all digital modes supported by your software. 95% of the digital modes you are ever likely to hear are either PSK31 or RTTY. So When it comes to transmitting and receiving, you will need to also connect your transceiver to the computer so that the tones generated by your software and sound card are sent over the air. Thus you have both IN and OUT of your sound card connected to your rig. You can also achieve control of your rig via the software and cause the rig to change frequency, transmit or switch to receive (and a few other things). Do do this, most hams have an interface that goes between the rig and the PC. The interface can be built for about $25 worth of parts, but many hams buy one. These interfaces range from the very simple and effective to the very sophisticated and effective . Some use circuitry that achieves full computer assisted operation and some do do it via simple use of VOX (Signal link). For most operations VOX will be fine but there are some more advanced applications that cannot be used via VOX.

[digitalradio] Field Day FLARQ Challenge
A Field Day challenge with a difference since Field Day is about preparedness. I will be operational during Field Day using FLARQ and a FLARQ beacon, in raw form it will look something like A FLARQ Beacon de K3UK 00uK3UK:72 CQ Field day de K3UK in Western NY. D3FE What I would like to achieve is 1 . An actual connect via FLARQ 2. Exchange of a message via FLARQ (either you send me one, or I send one to you) This achieves a goal of Field Day in that it will help operators gain more experience in using a mode that has error correcting methods, facilitates brief message exchanges, and avoids unattended operations. For simplicity, I will mostly use MFSK16 (it will stand out from the mass of PSK31 signals) but could switch to other modes when/if needed. I will try to be around 3583, 7073, 14073 USB and will post my actual QRG on the K3UK Sked Page http://www.obriensweb.com/sked in the digitalradio area.I may try various times, I will not be operational the whole Field Day, just a few hours. When actually operational... I will be on 3583 (or as close as I can get) 00 to 15 minutes past the hour 7073 16-30 past the hour and 14073 40 to 55 past the hour.I'll be glad to pass the formal Field Day exchange even though I am not actually going to be in a contest mode. If you feel like doing the same , set up your FLARQ station and beacon (in attended mode) To FLARQ, download the latest free copy of Fldigi at http://www.w1hkj.com/download.html Andy K3UK
