Re: [Elecraft] Is it possible to generate 1750Hz tone on HF with the K3 ?

A free software program which will generate one audio tone, or two separate audio tones, is TCube. This program can be found by Googling Tcube. The frequency range covered by each tone generator is 1 Hz to 10 kHz. Mouse clicks allow fine tuning in steps of 1 Hz. The output level of each

IT's hard to figure how a 1750 tone would control a repeater on HF. And, I doubt that the system is a true repeater. Possibly, it's a -re- transmitter- where a signal could be received, recorded, and then immediately re-transmitted. An unattended system like that would not be permitted

I *think* I recall reading about a freeware computer program that would generate US touch-tones (CTCSS) with a standard sound card. Google might be your friend here. 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com. For spots,

Touch-tones are DTMF (dual-tone multi-frequency). CTCSS is Continuous Tone-Coded Squelch System. They're quite different animals ;) Audacity as a tone-generator function. I'd try that first. http://audacity.sf.net/ 73, ~iain / N6ML On Thu, Dec 13, 2012 at 6:09 AM, Pete Smith N4ZR

I just found there is a SSTV repeater in VK5 on 14236 and it requires a 1750Hz tone for access, any way to do this ? 73 Cliff __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:
