Hello all DG'ers!

It's once again time for the Mount Baker Amateur Radio Club (MBARC)
Digital Group (DG) to meet "Brady Bunch" style on Zoom. We meet to
discuss all things digital (mostly data) in Amateur Radio. Of
particular interest to the MBARC DG is the use of the WB7FHC / AG7GN
Nexus DR-X units ( and HamWAN / AREDN
microwave networking here in Whatcom County.

MBARC DG meets the third Tuesday of each month at 19:00 Pacific. Some
of us gather early for casual chatting.

Zoom Link:

Topics for this meeting include:

Introductions of those new to Amateur Radio and/or the Digital Group,
including non DG guests.

Bryan Hoyer K7UDR will join us to discuss the grant proposal that the
San Juan County Amateur Radio Society is putting together to create a
new HamWAN node (and perhaps AREDN) nodes on Mt. Constitution on Orcas

Steve Magnuson AG7GN will discuss:
* The most recent updates he's done to the Nexus DR-X image -
* The breakage in the Nexus DR-X AX25 library and how to fix it.
* Demo of the flexibility of the Nexus DR-X in remotely powering
on/off a Yaesu FT-857 (with no relays!).

Budd Churchward WB7FHC will talk about doing our Sunday morning 09:00
fsq chats on a repeater versus simplex, which is becoming increasingly
hit-and-miss due to varying antenna systems, radios, etc. (FSQ works
fine on FM repeaters).

Andy Sayler KF7VOL and I will walk through our presentation of the
Whatcom County Multipurpose Remote Nodes we (tried to do) for the 2021
ARRL and TAPR Digital Communications Conference on Saturday
2021-09-18. The paper we submitted for inclusion in the 2021 DCC
Proceedings can be accessed at TAPR DCC 2021 - TAPR DCC 2021 -

I will touch briefly on some of the other interesting presentations
and papers at the just-concluded 2021 ARRL and TAPR Digital
Communications Conference.

Andy and Steve (AG7GN) may also discuss what they've been working on
as a Remote Node to be installed on Lookout Mountain.

Rob Sipes KG7GTC may have an update on the MBARC website - I have populated the Digital Group section of
the new website - please take a look -

I will discuss a request from the Bellingham Makerspace to include
some "Amateur Radio Eye Candy" for the Makerspace in time for their
Maker Faire on October 9th -
What I'm thinking of is interesting mapes (or other visually
interesting displays of Amateur Radio activity) on a monitor, running
on a Raspberry Pi:
* Display of APRS (web browser running for Whatcom County)
* WSPR display
* Suggestions for other interesting displays?

The usual show and tell of any projects or activities that you've done
that are "Amateur Radio Digital".

IF there is time, I'd like to lead a discussion (20 minutes max) about
projects / ideas for the coming year for MBARC DG.


The MBARC DG thanks Budd Churchward WB7FHC for the use of his
business-grade Zoom account for conducting the MBARC meetings.
