Re: C-Media PTT
I sm using?the CM108 PTT in FLDIGI successfully on windows. What leads you to conclude that it does not work on Windows? On Tue, Oct 29, 2024 at 12:29?PM Kenneth G. Gordon via <kgordon2006=[email protected]> wrote: Hello, All: --

You can also use hamlibs to key your radio and that's with both bsd & w$. GL & 73 Jaye On 10/29/24 9:29 AM, Kenneth G. Gordon wrote:

C-Media PTT
Hello, All:
I am using one of Kevin's DRA units with Fldigi, VARA-HF and Winlink Express in my daily traffic handling work. So far, it has proven to be the best digital interface I have ever used. I prefer to use the C-Media sound-chip's PTT function which is available with any of Kevin's (Masters Communications) DRA units as it is faster, more reliable, and is easier to contrtol than using VOX to key the transmitter. Fldigi has that funtion built into it, but it is apparently, only available to users of Linux. I have two computers here which can dual-boot either Win10, or FreeBSD ver 14.1. I much prefer to use FreeBSD over Win10 or any of the many distros of Linux. However, although I have "translated" the UDEV setup, listed in the PTT setup of Fldigi which is required for Linux to the correct settings of the UDEV-equivalent in FreeBSD (DEVD), I cannot get the C-Media PTT to work. My only solution to that issue here is to activate keying by VOX in the DRA unit when using FreeBSD. Although VOX can be acrivated in the DRA unit by moving one jumper, I am concerned that doing so will affect the use of PTT keying via the C-Media chip in Win10. So, my question to Dave and to anyone else here, what, exactly, are the commands in Fldigi which activate the C-Media chip's PTT function in Linux? I am hoping that by learning this, I MAY be able to "translate" those commands to FreeBSD. vy 73, Ken W7EKB -- This email has been checked for viruses by Avast antivirus software. www.avast.com |

musings on developing digital RF signal
The classic FLDIGI approach seems to be: - generate sound in software on computer - use D/A converter (sound card) to creat?analog signal - leverage modulator?in transceiver to produce AFSK signal I notice that there are a few transceivers, for example: -? which: - detect the frequency of the analog tone - apply direct FSK modulation of the transceiver: ?they adjust the frequency of the local RF unit?to encode the tones - this works only for single tone modems In principle, since the tone structure for a given modem modulation?is known (that is what we feed the PC to develop?the analog signal) we can use this as a fourier transform and then use an inverse fourier transform to produce the RF signal directly. Has this been done before? How much surgery?would be required on FLDIGI to implement?some version?of this? Thanks! AB1PH Don Rolph |
AndFlmsg modes question
John, A question about AndFlmsg modes... When my FLDIGI friends send PSK250R, the AndFlmsg app switches over correctly to PSK250R, and the copy is good. But when look at the modes list in AndFlmsg settings, I see six types of PSK250R modes; however, basic PSK250R is not one of them. ??? Thanks for all you do. . . . Rob? K6RJF? |
M1 Mac 14.6 Elecraft K4 FLDIGI not talking FLRIG
I am running the newest versions of FLDIGI and FLRIG. I am receiving RTTY nicely but I cannot transmit. FLRIG sees the K4 it will PTT the radio. ?I have FLRIG selected on FLDIGI but it will not PTT the radio. ?
?
I do not know why FLRIG can PTT the K4 and FLDIGI cannot use FLRIG to PTT the radio. ?
?
I am trying to use FLRIG for the RTTY contest and I was hoping to get this working.

Re: No receive on FLDIGI
Normally this is caused by the audio device setup in Flrig/Fldigi and maybe windows. Windows has a habit of messing with the audio. And also make sure the Signalink is on. This is what usually happens on our nets. On Sat, Sep 28, 2024 at 4:06?PM Al via <k2hro=[email protected]> wrote:

No receive on FLDIGI
My Icom 756-P2 & Signalink work great on WSTX. FLDIGI used to work but it quit.
?
The problem is FLDIGI or FLRIG.?? FLDIGI frequency readout works normally. At the bottom of the FLDIGI GUI the green VU meter shows normal received audio. The problem is that it won't even decode gibberish in any mode. I installed the newest versions and made sure the squelch is disabled. On transmit it keys the transmitter but there's no modulation (psk, RTTY). On cw, the Signalink relay clicks are normal (cq, cq) but there's no carrier.

thanks

what does RF spectrum of THOR 22 look like when sent by FM on UHF repeater
开云体育
What does? THOR 22? digital sound card mode ? RF SPECTRUM?? look like when sent over a UHF FM repeater (with permission of the repeater owner)
This was sent by the digital net control,
N3FLL, on Thursday Sept 19th. Note the presence of four clear sidebands on
the RF Spectrum, centered on the VFO carrier frequency of
446.525 MHz THOR22?? has? 18 closely spaced tones, sent one at a time, at? 22 tones/second. It is extremely robust on FM (VHF/UHF) and on
HF (SSB)? and does well at about? 80 word/minute. However, to access the FM repeater, a PL tone of? 100 Hz? was added (close lines next to carrier at 446.525) The amplitude of the TX audio was adjusted for a DEVIATION of about 2 kHz by the Bessel null method.
Note the RX audio level was set to? -17 dB? (not too loud, not too soft). It is important that the receive audio level not starve nor saturate the sound card. I've found that a level of?? -10dB?? to?? -20 dB? works well using a TUNE signal (single pitch sine wave at 1500 Hz).
My receiver was a RSP duo and sound card was a
Masters Communications? DRA-SR - all set for 1200 baud
(de-emphasized) audio.
The? RF spectrum of THOR mode looks very
different when sent on HF SSB.
