Update 2026-02-17:

I have heard from several sources that the satellite mode/doppler is not working in full duplex. You need to program the radio with fixed memory channels for RX and TX, just like the old Kenwood HTs.
I hope that AnyTone will get a firmware update in the future.

On YouTube several videos about the new Anytone AT-D890UV HT has been published that this new HT should have “real” Full Duplex capability – that is can transmit on VHF and receive an UHF without any desense.

In this video W8CPT demonstrates it’s full-duplex capability on SO-50:

Also there are in-built satellite functions with tracking and doppler control but it is not clear at this moment if this function supports full duplex doppler control.

Wimo says:

A special (and rare) highlight: the radio supports full-duplex crossband operation (FM). While transmitting on the 2m band, the receiver on the 70cm band remains active and is not muted.

From ANS-046 Feb 2026:

A recently released HT may be the best full-duplex HT available for FM satellite operations since the discontinuation of the Kenwood TH-D72 – the Anytone AT-D890UV (which is also available as the Bridgecom Maverick and the BTECH DA-7X2).

The Anytone AT-D890UV is a dual-band VHF/UHF DMR digital/analog handheld radio with built-in Bluetooth, GPS, and APRS capability. Features include Air Band AM receive, cross-band repeater mode, and an analog scrambler/compander. It has a 1.77″ color TFT display allows easy access to 4,000 channels and up to 500,000 digital contacts. The radio is powered by a 3100 mAh battery with convenient USB-C charging and upgraded 2G memory capacity. Next Generation Digital Narrowband (NXDN) functionality has also been promised as a future firmware update. A version of the firmware with NXDN support is currently available through unofficial sources.

The AT-D890UV also has the satellite Doppler tracking capability that has been present in previous Anytone radios, but unfortunately this feature does not currently work in full-duplex mode.

The below YouTube video from W8CPT demonstrates it’s full-duplex capability on SO-50, showing no apparent desense while operating in V/u mode.

The Anytone AT-D890UV is available from most amateur radio retailers for $299.99. As of this writing, DX Engineering expects to ship orders on February 23rd while Ham Radio Outlet has limited stock at their Anaheim location.

There will be 4 CubeSat’s on the upcoming Artemis II launch:

They will be injected into an 185 x 74.080 km HEO orbit and need to raise perigee with an propulsion system, otherwise they will re-enter and burn-up.

All of the CubeSat’s on Artemis II will only operate in S-Band:

Re-post from ANS-032 2026:

Thailand’s KNACKSAT-2 satellite is preparing for deployment from the International Space Station, with release currently scheduled for February 3, 2026 at 08:55 UTC (03:55 AM EST). The mission continues Thailand’s university-led CubeSat development program following the earlier KNACKSAT-1 mission. The project is led by King Mongkut’s University of Technology North Bangkok in Thailand, working with domestic and international partners to advance satellite engineering, payload integration, and on-orbit operations. The deployment is expected to be viewable live online via the project livestream at https://www.youtube.com/watch?v=aB4PIOS-hSs.

KNACKSAT-2 was transported to the International Space Station in late 2025 and is a 3U CubeSat designed to host multiple payloads. The satellite expands on KNACKSAT-1, which demonstrated Thailand’s ability to design and build a satellite domestically. Development and testing were conducted in cooperation with NBSPACE and other academic and research partners. The mission is intended to help Thailand develop multi-payload CubeSat platforms and prepare for future ride-share launch opportunities.

The satellite carries both educational and research payloads. Non-amateur missions include an Earth imaging camera, a store-and-forward IoT data collection system for remote sensors, ultraviolet radiation measurement instrumentation, and in-orbit evaluation of space-qualified components. These payloads are part of broader national workforce development programs coordinated through the Thai Space Consortium and academic partner networks. The satellite will be operated in orbit using ground stations located in Thailand.

KNACKSAT-2 also supports amateur radio operations through an APRS digipeater payload developed in cooperation with the Radio Amateur Society of Thailand. The amateur payload operates using coordinated frequencies through the International Amateur Radio Union (IARU) satellite frequency coordination process. The APRS digipeater system uses 145.825 MHz for uplink and downlink using FSK modulation at 9600 bps with AX.25 framing. The amateur satellite callsign assigned to the mission is HSØK.

In addition to amateur payloads, the spacecraft transmits engineering telemetry on 400.630 MHz using FSK at 9600 bps with AX.25 framing and a one-minute beacon interval. Following deployment, project coordinators have requested assistance from the monitoring community to receive, decode, and submit telemetry reports from the 400.630 MHz downlink, which is outside the amateur radio allocation. Many satellite observers actively search for newly deployed spacecraft and contribute reception reports, helping mission teams verify spacecraft health and early on-orbit performance. The satellite is expected to rotate in orbit, and ground stations are recommended to use circular polarization, with RHCP preferred, to improve reception reliability.

KNACKSAT-2 continues the growing trend of university-driven satellite programs contributing technical capability, education, and operational experience to the global amateur satellite community. University-built satellites are playing an increasing role in expanding access to space while supporting educational outreach and new opportunities for amateur radio experimentation.

The FO-29 Control team sometimes receives requests regarding the operation of Fuji No.3, but as they have already reported, more than a quarter of a century after its launch, the situation remains unstable. They regret that they are unable to operate Fuji No.3 in accordance with your wishes under these circumstances, and they ask for your understanding and continued use of her.

During February, the control team plans to send a command to turn on the transponder at the following times, but please be advised that if it is not turned on for more than 2 minutes after they start sending the command, they will terminate the command work.

February
6th 23:14-
7th 22:19-
13th 22:03-
14th 22:53-
20th 22:36-
21st 23:27-
27th 23:10-
28th 22:12-

Note: FO-29 will enter full sunlight around March 9.

Editor’s note: Full sunlight will hopefully allow continuous operation of FO-29’s linear transponder.
