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

John, thanks, I see it now further up the list. . . . Rob

Hello Rob, Look further up the list please. I have the single carrier modes listed first, then the multi-carrier mode below that. No problems. Glad you find the app useful. 73, John

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

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

What are you using for PTT? wrote: -- 73, AB1PH Don Rolph

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

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

Look up "Bessel Null". Simple with a half decent SDR, and accurate (in frequency) audio source. As Scottie used to say "You cane' change the laws of physics." 73 Dave G0WBX.

What I've never understood is why the SDR receivers that I've used do not offer a window that looks like an oscilloscope display of what would be the equivalent of discriminator audio, like the scope

I’m surprised to not see a reply. We did this some years ago on our local net. It works wonderfully. Volume setting is a big obstacle when working across multiple repeater hops and this normalizes

OLIVIA VS. THOR I find it interesting that the daytime 80m NBEMS nets (Pa/NY/NJ/NH) tend to use THOR22 (78 wpm and 500 Hz) for checkins and THOR32 and MFSK32 for traffic (FLMSG). Prop paths around 7-9

good copy tonight at 7:30 PM EDT from Philly on? 3582.500 kHz (vfo) and @1500 Hz on waterfall with Olivia 8/500 mode Good steady signals tonight received on my 140 ft end-fed NVIS antenna. Was able

Greetings all, Every Thursday night at 19:30 pacific, the Western Digital Net begins taking check-ins on 3.581 MFSK-32 @1500 waterfall. We are looking for interested ops to join in, train, and be able

Setting Optimum RX audio levels It helps to set the amount of RX audio your sound card sees (hears) carefully. Whatever digi audio meter you decide to use for RX levels, I found that decoding works
