I have seen many CMS HF stations now reporting they will no longer
be supporting winmore after the end of July. Also heard that ARDOP
is being abandoned by winlink. So that leaves VARA as the only
current solution for email over HF.

I am not happy that the VARA Team has chosen to make their product
commercial. Rather than follow the winlink model, with an optional
donation option. I have supported the winlink product by donating
over the years and will continue to do so, but don't think I will
support VARA, as I don't like their business model. But since the
other options are going away, will use the eval version of VARA
until something better comes along.

would be delighted.

PM Paul Butzi (W7PFB) <w7pfb@...
by the Weekly Net check-in via Winlink I have been
experimenting with Winlink again.
In particular I was interested in what changes happen as a
result of the abandoning of the Winmor connection
The direct replacement for Winmor is ARDOP. I have used ARDOP
for a while, it is more reliable and perhaps a bit faster than
Winmor but not a dramatic improvement.
So I decided to try VARA.
The downside of VARA is that if you want it to go into fast
mode, and you want to avoid the nag screen, you must buy a
license, which costs $70.
The upsides are:
* VARA is faster, especially in good conditions when you can
run a fair bit of power on your end (most of the Winlink RMS
stations seem to run pretty solid signals). On a really solid
connection, VARA is massively faster.
* In any conditions that are less than ideal VARA is
dramatically more reliable and faster than any of the non
PACTOR alternatives. As PACTOR TNC’s cost more than $1k, that
makes $70 a pretty good deal. (I don’t own a PACTOR TNC so I
don’t know how the various PACTOR modes stack up against VARA)
In short I can connect to more Winlink RMS stations using VARA
than I can using Winmor or ARDOP. I can connect more reliably
when conditions are not optimal. I can connect reliably using
5-15W instead of 30-70W. And the connections are faster.
In short, I think it’s a pretty interesting piece of
And that’s all on HF.
There’s a version of VARA for VHF/UHF FM which can exploit the
wider audio bandwidth you get when you use the 9600 baud
receive data path of a VHF/UHF radio that offers input/output
for a 9600 baud packet modem.
This would get around the big problem with VHF/UHF Winlink,
which is that packet radio is deadly slow. The slow speed of
packet is the flaw that makes VHF/UHF Winlink nearly useless
for tactical use in an emergency. There are other problems
with VHF/UHF Winlink but the flaw that cannot be ignored is
that it is just too darn slow for modern needs like moving
digital photos or larger files.
I’l be ordering some hardware to allow me to exploit the wider
data path you get using the 9600 baud audio path - basically a
couple of wide bandwidth sound cards.
Is anyone else interested in experimenting with experimenting
with VARA on VHF/UHF FM? If so, let me know and we can
Also, if you’re a Winlink HF user, I urge you to check out
VARA. The evaluation copy, speed throttled as it is, is still
a dramatic improvement over Winmor and ARDOP, especially in
