Ham radio firmware roundup, week 37 2026: Tidradio TD-H8 (2nd Gen) 230923, Tidradio TD-H8 (3rd Gen) 260130, Tidradio TD-H3 250317

The week in short

• Most of what the tracker recorded this week is archive material rather than brand-new firmware: whole version histories arriving at once as manufacturers get added to the ham section for the first time.
• Full version histories with in-week dates came from SharkRF, AOR, Green Heron Engineering, KM3KM Electronics, Palstar, Afedri SDR, Radtel, Baofeng, Quansheng and Connect Systems.
• Around 200 products were newly tracked, from Lab599, AOR, QRP Labs, SharkRF, Ailunce, ACOM, OM Power, RF-Kit, RigExpert, Arcom Controllers, microHAM, Green Heron Engineering, KM3KM Electronics, Palstar, Afedri SDR, Radtel, Retevis, Baofeng, Quansheng, Connect Systems and Tidradio.
• Every version listed here was published by the manufacturer on its own site.
• The data we hold is versions and dates only, so what each release actually changes is in the manufacturer's release notes, linked from each product page on updatemystuff.com.

Notable updates

SharkRF (7 September) — the complete hotspot firmware history landed in one go, so the shared date is an import artefact rather than a day of frantic releasing.
