Or, perhaps, the "amateur RMS" has an older PACTOR modem that is limited to P3. Mark - AD7EF

Where are those "amateur RMSs" located? If they're in the US, perhaps the controlling software on the RMS side is setting their modem to max out at P3. Mark - AD7EF

I have found that running both SHARES and amateur with the 7800 set to P4 when using amateur RMSs, it only links at P3 speeds.?
Not a scientific study. Just my observations.?

Re: VARA HF v4.7.7 has AES 256 encryption option for NON HAM users ONLY
i should have explained further. I already was using a physical PACTOR DR-7800 modem which includes SCS ALE and AES256 firmware. I use CoolTerm to control it as the SCS Chat ALE software does not allow full of the modem. NOW VARA HF Winlink (and P2P) have the encryption option) so a number of operators are using that over buying an expensive PACTOR modem. The VARA encryption is working well so far. When you connect to another station the VARA screen turns a nice ORANGE colour to alert you tht encryption is running. Of course I am using VARA's own included software modem. So far so good!

Re: VARA HF v4.7.7 has AES 256 encryption option for NON HAM users ONLY
In the past VARA has worked very well with pactor using BPQ or
Winlink to poll both modems. Its using one or the other. Not both
at the same time. I am hoping that the powers that be will allow
AF MARS to resume using VARA with this new encryption method.

Hi Jim,
For non-ham operations (CFARS)? I use encryption both with VARA (nice to have!) and PACTOR.?

Don't feel bad, the old kenwood radios are still better than most radios on the market today. This is why even used they are priced at $200 for a TH-D7, $300 for a TH-F6, $500 for a TH-D72, and $600-$900 for a TH-D74....?
:)?
All of these radios perform very well with VaraFM, Packet, APRS, etc.. i use them all regularly.. ?
I tried to use Baofeng, Anytone, etc and they all FAILED regularly.. ?
The usual culprit for not being able to complete the connection is the lack of power and decent antenna. ?In fact, I was having troubles with a Yaesu FT8800 connecting to a local digipeater (Packet RMS) and used an HT on the same antenna to verify that I can connect to it! :) ?Turns out the Yaesu had a setting I didn't know about.

The TH-D74 is a handheld.
When you see Kenwood naming, the H in TH is Handheld.. The M in TM is mobile..?

better yet - programs could be customized to align PTT timing

This has been done since the beginning of
packet in the very early 1980s.? It's called a setting called
TXD (TX Delay) and determines a delay between PTT and the
beginning of the data tones. Usually specified in
milliseconds, it is user adjustable to correct for the
"slow-on-the-draw" issues of individual radios.
Since the group here is on the topic of VARA -
can you explain where in the VARA software you adjust TXD?

It's not "just audio".? If the class-D amp

This doesn't affect modes like AX.25 packet

multiple SIMULTANEOUS audio tones like VARA, MT-2000, etc.,?
If it's "not just audio" what other waveforms
