Re: Soundcard device missing in action!
Thanks to help from Jason at Signalink, I believe the problem is solved.? I had everything set up properly, but my antivirus wasn't allowing use of the microphone.? After I went in and authorized the use of the microphone by the apps, the systen started working as it should.
Thanks again to Jason for his help.? He is knowledgeable and patient.
Mark,
I am using the data cable that came with the SIgnalink.? It has the round 6-pin connector on one end (for the DATA connector on the radio) and the RJ-45 connector on the other end.
I called Kenwood earlier and asked if the DATA connector was always hot, and was told that yes, it is always hot.
There is Menu 45, which can enable DSP filtering for the DATA connector.? Menu 45 is either "on" or "off".? I've tried it both ways to no avail.
I've checked the jumpering a couple of times, especially SPKR to pin 5.? I installed jumpers per Signalink instructions, but I now wondering if I haven't done something wrong there.? I may order the plug-in module to remove any doubt.
Thank you for your reply, suggestions, and patience.? Hopefully, we will win this battle.

John; Since you don't (currently) have CAT rig-control set up, it appears that you're using the 'VOX' circuitry in the SignaLink to key the radio, and you're feeding transmit audio from the SignaLink to the radio. That indicates that the SignaLink, and the USB interface with your computer, is working I haven't seen any mention of the cable you're using to connect the SignaLink to the transceiver... Which connector on the radio is that cable plugged into? Is there a menu option on the TS-480SAT that enables the receive audio onto that connector? If you're certain that receive-audio is being routed to the connector that the SignaLink is interfaced to, perhaps there's a problem with receive-audio wiring in the interface cable. Keep in mind, also, that the jumpering inside the SignaLink controls how the receive-audio from the RJ-45 connector is routed to the audio input of the USB-audio IC in the SignaLink. You also said (in a later post) " I am beginning to believe that radio control (CAT control, rig control) of some sort is a necessity for VARA HF/Winlink to work."... ?That certainly isn't so! However, having CAT control for Winlink HF is exceedingly convenient. CAT control also makes it possible to key the radio via CAT, instead of the SignaLink 'VOX' circuitry, which can significantly improve VARA HF throughput. Mark - AD7EF

Re: VARA-FM Highly Variable Throughput
I haven't seen it mention in this thread yet, but the FT-991A isn't VARA Wide capable even with a external sound card.? The radio lacks a data out pin that by-passes the filtering.? Search this group for 991 and you will find plenty of discussion.? I haven't used an IC-7100, but the manual shows an AF OUT and DATA OUT pin.? The DATA OUT pin should provide the bandwidth for VARA Wide.
VARA FM has interesting behavior when set to Wide with a radio that isn't capable.? The initial handshake only transmits in the lower 3000 Hz, so it doesn't test in the 3000-6000 Hz range.? After the handshake, it begins sending the message at a high level if the S/N was good.? The problem is half the bandwidth is missing, so VARA steps down a level and retires sending the message.? It will continue to do this until it hits Level 3, which has a ~3000 Hz bandwidth.? Sometimes it might even drop to Level 1 or 2.

1)??? The diffraction "smears" the wave front and creates
multipath-type distortion.? This doesn't affect the "calibration"
much which uses simple two-tone FSK, but just kills the complex
multi-tone QAM audio subcarriers of the fast modes of VARA (or
9600-baud AX.25 packet).
2)??? The diffracted signal on the far side of the hill will be
far far weaker than the signal hitting the near side of the hill
--- as much as 20-30 dB less.? I.e. far far more path loss than a
line-of-sight path of the same distance.? High-speed data modes
require fully-hard-quieted "full smash" signals to work reliably.?
Even the slightest amount of hiss or "popcorn" noise on the
received signal will be fatal. ?
Normally, this means a true line-of-sight path --OR-- a LOT of
power (50-100 watts or more) and/or lots of antenna gain. And
further, since this is a two-way handshaking operation (unlike
one-way APRS beacons), this has to be true in both directions.??
10-20 watts into a low-gain vertical omni low to the ground? just
won't hack it, unless the other end of the path is on a

Re: VARA-FM Highly Variable Throughput
While it is true that P2P winlink is a pain, there are a couple of additional factors involved.?
1) the size limitation of any attached files. IN the SET, which is based on actual fire, one of the stated requirements is ability to send floor plans from the EOC to the incident command. RMS may not be able to handle the size of the attachment.
2) The speed. VARA FM wide may not be available as the local area VHF maybe be in hot zone (plan for the worst, hope for the best)
3) avoiding something just because is a pain in the neck is not a reason to avoiding using something. What works should be the bottom line

Be aware that the built-in "soundcard" of the FT-991 does not
have enough audio bandwidth to do VARA-FM Fast.? You have to use
an external interface like a DRA or recent SignaLink connected to
the 6-pin MiniDIN port to do VARA-FM Fast.?
As for the terrain, I think you may not realize how much relief
the terrain in your shots has.?? Especially with antennas up only
10-25 feet.
Here are maps and profiles generated by Delorme Topo North
America 10.0 .? If you are not familiar with it, it is a DVD-based
continuous street level map of all of North America including
Canada and Mexico as well as the US.? This is cached entirely on
about 5 GB of the local computer's hard disk -- no Internet
connection is required, so it works in the boon docks with no cell
connectivity. The underlying relief data is the NASA/USGS "Shuttle
Radar Topography Mission" data set that relief-mapped the entire
land mass of the earth to a common datum in about two weeks about
two decades ago. ?
Like Microsoft MapPoint and Street Atlas, Topo N.A. can use a GPS
for real-time navigation. You can plot points from entered WGS-84
coordinates derived from other GPS devices.? More usefully for
radio purposes, you can draw a line between two push-pinned points
and create a cross-section profile of the rise and/or fall of the
terrain between the two points.? You can also profile a
high-lighted route on roads to determine the most extreme gradient
you will encounter, before you try to tow an RV up mountains in
the boondocks.? Here are the paths between all three pairs of
points you posted.? Note that all 3 paths are non-line-of-site
paths that graze mid-points substantially higher than the end
points.?? Note that these profiles UNDERPLAY the problem because
the graphs DON'T take into account the curvature of the earth's
surface.

Re: VARA-FM Highly Variable Throughput
Interesting information.? This is exactly why we don't recommend using P-P Winlink.? Too much coordination required and too much unpredictability.? The best thing is to find some reasonable RMS stations that you can use.

The snapshot appears if you view it on the Groups.io VARA-MODEM page.
DoC I think the file is being overwritten because Windows does not detect the sound card and defaults to entries that do exist in Windows 10.
Are you testing the same sound card and USB cable on both PCs? On the Windows 10 PC did you try a different USB port? Are you going directly into a USB port and not a USB hub?
Sorry about posting so many questions but I'm just trying to narrow it down to the cause.
