You confuse bauds and bit Per seconds. Gaussiam error are for a given electrical change in the signal Per seconds. The goal of modulation like Vara is to put a maximum of bits in each electrical

I use the Alinco DR-135T for my RMS Gateway station and it easily runs VARA FM Wide using a Masters Communications DR-50 interface.

Excellent! One small errata and some speculation. The mini-DIN on the FTM-6000 is a 10-pin connection. I speculate that the FTM-6000 is built on the chassis and base radio of the C4FM/WIRES-X capable

Classic packet radio uses direct FSK modulation. The technology available at the time to the average ham, both in computer software or TNC hardware was quite limited, there were virtually no noise

I just tested a Yaesu FT-2980 & Signalink USB, and I got 16,932bps send on a test message and 14,144bps receive. Its not VARA Wide's higher speeds but its still decent for a cheap 2 meter radio. 73

Good hint but I do challenge the statement it being hard to find radios suitable for wide VARA-FM. Look at Moto CDM750/1250/1550 or many other similar commercial radios, they provide wideband and flat

All the current Yaseu mobile radios work fine also. Chris N7GYL [email protected]> wrote:

It hard to find VHF radios that have the ability to run VARA FM WIDE. Right now there are two ALINCO dr-150T radios on Ebay. This radio was released prior to 2000, and as packet was still common, it

Hi Bill, Just to add a little to this thread. ?I had been running WE/VARA HF using Parallels and Win 11 (ARM) on an M2 Apple laptop. ?Recently I noted that after several assorted upgrades, the

How does the "Random Negotiated" part work? How many random characters are given? Do you have any information on this?

How can I access version 4.3.6 of VARA HF? Also, I am curious about the experiences of those who have tried the encryption in VARA HF. One thing I noticed is that a user with encryption can

At the moment, I only have mono-band hamstick-type antennas for 60 and 30 meters for the dedicated APRS-HF (AX.25 & VARA) radio in the mobile. I am considering investing in a pair of 40M hamsticks.

I wish we could get you to join us on 40m. We've been doing it since November. We've tested every which way and it's amazing stuff. I'd say all your previous tests pretty well shows what works.

This just conforms what I said in a previous post -- that FM voice comms must be fully hard-quieted before data is going to work decently.? Signal levels with hiss or "popcorn" on them, that remain

Chris et.al. Congratulations on a job well done! The observation that the VHF path deteriorated as the sun came up is normal VHF line of sight propagation. This effect is also seen on VHF repeaters

We ran the "live" test today - a simulated emergency based on an actual one 5 years ago with all the public safety services involved. We were handed several files on a USB stick to send. Most were

Mark, This is what we found through experiments and looking at schematics. ?I think Vara is a great program. ?We have done a good amount experimenting and training in our ARES group. ?For the most

Jeff; There currently isn't any "all ?band" (HF + VHF/UHF FM) transceiver that will support full-throughput 'WIDE' mode VARA FM (or 9600bps PACKET), on 2M or 70cm, using the internal USB sound-card

Phil, We tried to get the FT-991A running Vara Wide with the internal soundcard by changing the different settings.? We could not find any settings that would produce a flat signal with a ~6 KHz
