WinDRM and HamDRM are good examples of modes where all functions shoud be legal in the image/phone segments in the U.S. but sending a text file in most HF image/phone segments is dissallowed by current rules. The crazy thing is that you can render the text as glyphs and send it as an image but not do the most efficient thing and send the ASCII codes. There is no practical reason that user's of WinDRM or HamDRM shouldn't also be allowed to send program files but if it isn't intended for direct printing or displaying it's technically illegal.
Other than 160 meters, 7,075-7,100 kHz is the only other segment that allows mixed voice, data, RTTY and image. 73, John KD6OZH ----- Original Message ----- From: Leigh L Klotz, Jr. To: digitalradio@yahoogroups.com Sent: Thursday, May 03, 2007 02:04 UTC Subject: Re: [digitalradio] Digi Voice: No Bandwidth Limit I would like to try some of the DRM-based modes which allow you to send voice, pictures, and text. I suppose I could do thos on 160m, now that I think of it. 73, Leigh/WA5ZNU On Wed, 2 May 2007 7:58 am, [EMAIL PROTECTED] wrote: > If it is true that others are not being held back, what actual new > wideband HF modes have been developed that we can not use in the U.S.?
