Upgrade results: DX-286 first, then ML-880, and finally ML-880 with NR. Very strong wind caused quite a bit of noise in the audio. Yeah, I damaged the front glass panel while taking it apart, so now I’m looking for replacement options. Sorry about the audio quality. #radio #sdr

I made two mods to the ML-880: added ferrite beads to the speaker leads and applied 3-ohm conductive shielding film to the display. The ML-880 no longer reacts to hand capacitance, and the noise level is lower now. Finally, I cracked the receiver’s plastic front panel(((

Mike Bazley, VK6HD, was a legendary Australian ham radio operator. I was fortunate enough to work him on 160m CW, and I’m proud to have him in my log. The QSL card from VK6HD is something I truly treasure and will always remember.

@AlanDXSWL I was told to select the Hi-Z mode for the telescopic antenna — and yes, after that the HF signal became stronger. I need to do another comparison test.

@RA4SD That radio was on my list of things to buy as soon as I could. I think I'll wait for an upgraded version.

The MLite-800 is basically deaf on LW and MW. The DX-286 - winner! There are mods for it — it really needs shielding around the display, and the audio codec is noisy too.

The DX-286 receives noticeably better — solid 5/5 from me. The ML-880 has display noise issues, so I’d give it 3.5/5. There are some mods for it, and they’re definitely worth doing.

FMDX test: DX-286 vs MLite-800. Reception is basically identical — both use the TEF6686. The ML-880 locks onto RDS really fast!

Shortwave reception test: DX-286 vs MLite-800. Which one comes out on top?

Just received the new MLite-880 today from the Malachiteam guys! Lots of reviews already floating around, but I'll be doing my own testing and comparisons. Stay tuned! #HamRadio #SDR #MLite880

Out for a pleasant early morning pedal on the 14-inch wheeled folder. Brilliant little bike, holding a decent 14 km/h average 🚴

New Zealand — one of the toughest DX contacts I’ve made on 160m! CW from a noisy city QTH! #160m #TopBand #CW

@erickdahan Erick, thanks for the reply. My ham radio activity is mostly on hold because of the war with Ukraine (I'm against war). My current QTH is very low, with a lot of utility wires around the roof, so these days I’m mainly active as an SWL.

Spent nearly four hours up on the roof doing post-winter maintenance. Reworked the antenna mounting hardware, and one of the guy lines failed — the turnbuckle actually snapped clean in half! First time I’ve ever seen a failure like that. #antenna #radio #hobby #swl #dxing

The LZ1AQ antenna is still my main homebrew RX antenna. There are plenty of clones around, but building the original version properly takes real technical skills — just like the 4-in-1 RX ANT. #radio #sdr #lz1aq #antenna
