I also listened in to the Astronaut audio on the downlink frequency of 145.800. The signal was S9+ for the 15-minute QSO. I used a Diamond F22 antenna with a Kenwood TS-2000 xcvr.
Later, I found the YouTube video and heard the kids’ side of the QSO:
Great work by Fred! Now, if only the squelch were softer.

Hi Ed,
The above info is correct. I can speak to the DMR repeater availability:
HudsonDMR 147.105+ CC0 (Talk Group 3181 networks to 95 repeaters. TG 3133 only NH repeaters) Many other TG selections, including SKYWARN. See NEDECN.org website
Derry DMR 145.310- CC1
Chester DMR 145.19- CC9

The Merrimack Valley Digital Network has more nodes using AREDN mesh networking. See: https://merrimackvalleyara.org/mv-digital-network/
Also: https://worldmap.arednmesh.org/#8.32/43.094/-70.764
Zoom in to NH/MA/ME
MVARA will have a demonstration at NEAR-fest on Friday and Saturday.
Yes. Here are some of the nets:
Mondays @ 8 PM “New England Wide” TG 3181, TS 2 on all 95 repeaters
Tuesdays @ 7:30 PM “Vermont State” TG3150, TS2 on all VT and ‘nearby state’ repeaters
Thursdays @ 7:30 PM “SKYWARN” TG 759, TS1 on all 95 repeaters
Thursdays @ 8 PM “Office Hours Tech Net”, TG8801, TS1 ‘on demand’ on 95 repeaters
Saturdays @ 10 AM, “South Shore Hospitals” TG8851, TS1 on SE MA repeaters
Sundays @ 8 PM, “Providence Radio Assn”, TG8801, TS1 on RI, MA, NH repeaters
There are local DMR repeaters in Hudson, Derry, Chester, Goffstown, Francestown, Chelmsford and Haverhill. A total of 95 repeaters in the networked New England NEDECN. See: https://nedecn.org/ for more information.

I am not familiar with the VRM850. Only other thought is to post on the GEMOTO email group.
That is a good question for the “Repeater Builders” Forum:

I primarily work with stock Motorola repeaters, but there have been some issues with hex editing code plugs on Motorola repeaters “to get them into ham bands”, when they were originally out-of-band. The Hytera radios did not work, but Motorolas and other models did work.
Most electricians carry a Megger. You don’t want a resistance between your house electrical ground and your station ground.
Motorola R56 Site Standards for Light Duty Type “A” sites shall have a grounding (earthing) electrode system resistance design goal of 25 ohms or less for a single grounding electrode (NFPA 70-2005, Article 250.56; MIL-HDBK-419A, section, 5 ohms or less for a “Standard Duty “Type B” site.
2.2.2.1). See Section 4 and 5 of

These instruments induce a test current into earth systems and measure ground resistance in multi-ground installations without needing to disconnect the ground.”
