[SkyHub] Support Needed for 2026 Repeater Expansion Projects

[Skyler Fennell]

Over the past year, your support has allowed us to continue expanding the
SkyHub network. Although our last fundraiser in September 2025 reached only
about one-third of its goal, we successfully commissioned the *La Veta Pass
repeater*, bringing coverage to a previously underserved area near
Walsenburg. We also completed the Trinidad repeater system, which is
awaiting site access for installation, and brought several additional sites
online, including *Sandia Crest* in Albuquerque. Please visit
*skyhublink.com/support
<http://skyhublink.com/support> i*f you would like to help out!

We are now raising funds for two infrastructure projects.

The first is a new repeater installation on *Hoyt Tower*, with a target
completion of *August/September 2026*. At approximately *2,000 feet above
ground level*, Hoyt Tower is the tallest structure in Colorado and provides
an exceptional opportunity for wide-area coverage in Eastern Colorado for
Edge of Space Sciences, Severe weather, and emergency communications for
I76 and I70 eastern routes. The repeater, duplexer, and antenna have
already been acquired. Funding is needed for approximately *400 feet of
hardline, connectors, grounding materials, and installation hardware*. The
antenna will be mounted at the 300' level and there is a 100' ice bridge.

The second project is restoring the *Sandia Crest* repeater to service. The
site's high RF environment has proven that the existing 4-cavity duplexer
does not provide adequate isolation, requiring the repeater to be taken
offline to protect our equipment and other users. Replacing it with a *6-cavity
high-isolation duplexer* will allow the system to return to service and be
linked back into SkyHub.

The total project cost is *$1,873.00*. An initial *$300.00* donation has
already been received, leaving *$1,573.00* to raise.

If approximately one-quarter of the recipients of this email contributed
*$20*, the remaining balance would be covered. Contributions of any amount,
or donations of compatible equipment and components, are equally
appreciated.

*New Donation Platform*

We have moved our online donations to *Zeffy*. Unlike many fundraising
platforms, Zeffy does not charge transaction or platform fees to nonprofit
organizations, allowing *100% of your donation* to support our projects.
During checkout, Zeffy may ask if you would like to leave them a tip. This
tip is *optional* and can be reduced to *$0* if you choose.

You can donate at *skyhublink.com/support <http://skyhublink.com/support>*

A line-by-line breakdown of the requested equipment and costs is included
below.
Thank You, and we appreciate ALL users of the SkyHub
