makerworld.com/en/models/2401… Thom, W8TAM, has created a mod for the TK-x90 radios to use Anderson Powerpole connectors directly for the power connection.

We now have TNC cables designed for the Yaesu FTM mobile radios. We also have the MiniDIN-6 adapter (CT-164 equivalent) and a MiniDIN-10 bare cable (CT-167 equivalent). store.mobilinkd.com/collections/ft…

TNC4 firmware version 2.5.14 has been released and the User Guide has been updated. The TNC will indicate when its audio input is being overdriven. PTT lockup on iOS when 2 or more apps are attached is fixed. 9600 baud modulator and #M17 demod is improved. mobilinkd.com/downloads/?dl_…

github.com/mobilinkd/Nucl… These changes are now released. As part of the ongoing repo re-org, the NucleoTNC firmware now has its own Github repository. The fine frequency adjustments to the ADC and DAC timers works pretty well.

Should have a firmware update to the NucleoTNC out soon that improves #M17 performance. The oscillator is off by about 100ppm due to the way MSI PLL mode works. Micro-adjustments to the ADC and DAC timers can bring that to within 4ppm. Also, a DC offset bug is fixed. #hamradio

While we love selling our aluminum NucleoTNC enclosures, the fact that there are two distinct 3D-printable NucleoTNC enclosures on Thingiverse is so heart-warming to see. #OSHW A huge "thank you" to all those that contribute to #opensource #hamradio. thingiverse.com/search?q=nucle…

The #hamradio NucleoTNC repository is being split into 3 separate repos. The PCB, spacer, and enclosure KiCAD files are now #OSHW licensed under CERN-OHL-S and available here: github.com/mobilinkd/Nucl…

If you have a Rev B NucleoTNC board and want to use it for M-17 data, swapping out C1 & C2 for 22uF 16V+ caps is recommended. This is one of the changes on the Rev C board & schematic.

Easy modification to an #STM32 Nucleo32 board to allow SWO debugging while preserving LD3 functionality. This allows using SWO when debugging the NucleoTNC (mobilinkd.com/2019/06/24/nuc…). #hamradio

Here is an update for the special #UVK5 firmware I've been working on supporting #hamradio digital modes (flat response) to fix an issue with frequency drift caused by varying DC bias on the BK4819's MIC line. github.com/mobilinkd/uv-k…

I have misplaced my Nooelec NESDR in the move. I am relegated to using a backup #rtlsdr, one without a TCXO which drifts like crazy. It's got errors in the 55-65ppm range depending on which direction the breeze is blowing. #hamradio

Does anyone know where I can find this 3-pin battery connector? This is a 3mm pitch, 10mm tall, through-hole part found on the Quansheng UV-K6. I am looking for a part number or source. #uvk5 #uvk6 #hamradio

@TakagawaU16 This firmware version adds a "DIG" (digital modulation) mode which bypasses DC filtering, sub-audio HPF, emphasis, 3000Hz LPF, TX audio filters, and disables MIC AGC and AF ALC as specified for "DMR scheme" in application note. It provides a flat response from BK4819 IC.

Is this firmware better than F4HWN v2.7? What is a remarkable point?

Mobilinkd -- Find us @[email protected]@Mobilinkd

Custom firmware (egzumer fork) for Quansheng #uvk5 #uvk6 with support for digital modulation mode is available here: github.com/mobilinkd/uv-k… This provides a flat response in TX and RX. A few small hardware mods are needed. These will be documented in detail soon.
