FLDIGI Training Net - via Zoom on Saturdays at 9 AM
¿ªÔÆÌåÓý
???????????? FLDIGI Training Net? -? via Zoom and on 80/40 meters
When:? 1st and 3rd? Saturdays of each month at? 9:00 AM? Eastern Time via ZOOM ?? Zoom link:?? ?? by RADIO:?? 80 meters (3583 kHz) and 40 meters (7068 kHz) VFO dial? at? 1500 Hz on the FLDIGI waterfall
This will be offered for rookies as well as those with experience with FLDIGI / FLMSG / FLAMP / FLRIG
We will begin with an introduction of FLDIGI each session and then ask for questions and comments. I am attaching a PDF of some of the fundamentals
of FLDIGI I made a few years ago.
Topics each session:? Casual chats,? DX,? EMCOMM traffic, or whatever comes up. I will begin today (Saturday May 03? at? 0900 hr EDT) de k3eui? Barry Kennett Square PA

The most common question I get about FLDIGI is either how to achieve PTT (send) or rig control (CAT) on my XXXXX? rig.
?
Most radios have USB ports where with the correct "driver" you can use a COM port for either PTT or CAT.
?
I like to use FLRIG where all of the heavy lifting is done for you.
?
Rigs with internal sound cards (Icom 7300, Knwd 590S, Yaesu FT991A) are usually easy since there is no external sound card to mess with.
Just be sure that the TX LEVEL and RX LEVEL are set appropriately in the MENU of the rig,? and on the software controls (TX attenuation).
?
?
If you have a rig with the external soundcard? Tigertronics? SignaLink, then you do not have a COM port, and you only have a LEFT channel audio, so with a Signalink you allow the built in VOX control inside the SignaLink to trip the PTT relay inside the SignaLink.? Tigertonics suggests leaving the Windows SPEAKER output for the Signalink at 100% to insure enough audio for PTT inside the SignaLink.? There is also a jumper (J4) inside the Signalink that allows users to adjust the sensitivity of the PTT voltage.? The third knob on the SignaLink (DLY) is the hang-time DELAY; that is, the time your PTT stays in TX mode before releasing back to RX mode.? Typically leave the DLY knob at about 9 O'clock when using FLDIGI or FT8.? It needs to be at about 7 O'clock for the ARQ modes (Winlink).? The TX and RX knobs on the SignaLink ought to be near the mid-level of 12 O'clock, but you can adjust as needed.? And remember - LEFT channel for TX audio.? The RIGHT channel has no output on a Signalink.
?
?
On SSB, be sure that the power output is consistent with the manual (25W on a 100W PEP rig is enough) and be sure that the ALC reads zero or close to zero.
?
CAT control is quite easy once it works.? That means that all sorts of functions (VFO, bandwidth, mode, noise filters, etc.) are controlled by the software.
A CAT uses a COM port and can often also do the PTT (send) function.
I always try to use FLRIG - and follow the default settings.
