WSJT-X 2.5.0-rc3 and MAP65 3.0-rc3 are out.

The release notes athttps://physics.princeton.edu//pulsar/k1jt/Release_Notes.txt suggest this is mainly a bug fix release.

📻 🌔

Yesterday around noon I worked from IM98rh a bunch of European (mainly UK) stations in SSB and CW with My Xiegu G90, an Ukrainian 28/70 MHz transverter, and the slim Jim antenna kindly made for me, placed roughly horizontally, NW–SE.

The RSGB NFD contest was on.

Two stretched coat hangers, one Nivea cream box, an electrical block, a coax choke wound to the PVC pipe with duck tape: a rotatable horizontal-polarization centre-fed half-wave dipole for the 70 MHz band. Nice QSOs with EA5IYK Mark, EA5IZX Carsten and EA5IZO Richard, in a range of 8 to 40 km from me. It happens to be quite directional. When working EA5IYK, (about 40 km), having my dipole off by 60° reduced my signal by about two S-meter points.

Doing licence-free "amateur radio" with sets without breaking any of the EU-wide rules for the band may involve physical exercise, style: since one can only do simplex, with the built-in antenna, 500 mW, and HT in hand, one has to walk up to high places. That does not exclude interesting contacts and even DX when tropospheric propagation kicks in.

Last Saturday I climbed (again) to foggy Serra Mitjana (EA5/AT-099) but this time I convinced friends to try a activation; I brought my Cobra Microtalk MT-600. I made 15 contacts, of which 4 qualified as "legal" PMR446 to-PMR446 contacts. Blog post ea5iyl.blogspot.com/2021/02/a-:

Chinese transceivers have a very basic 3-pole filter and are known to produce strong (non-conformant) harmonics in TX. But wouldn't using a resonant antenna further attenuate at least the even harmonics?

I started a blog and published a post describing my experience, just in case it is helpful to other fellow hams: ea5iyl.blogspot.com/2021/02/my

The 47 kΩ BFO potentiometer in one of my Pixies was broken. Having no replacement, I installed two resistors (22 kΩ and 33 kΩ). Now RX is 7023.68 kHz, 540 Hz above TX, 7023.14 kHz. A tone of 540 Hz when a station zero-beats me (chirp allowing) is a bit 'bass' but should work.

It kind of worked! Ops were very kind to me: thanks

It was hard to pick up their signal and my keying was awful. My antenna connection was flaky, and I broke my Chinese key at ~09:40Z. Nice flat summit for my dipole! I also broke my glasses, but that's not a radio-related accident ;-)

Decided. I'll hike this morning to EA5/AT-099 Serra Mitjana with a 7023.2-kHz 0.3-W Pixie and a CFHW inverted-V dipole. I'll be there around ~0900Z, QRPp and QRSs. Receiving with a DSB receiver will be tricky, as I'll also hear OMs in other nearby frequencies. I'll spot myself at SOTAWatch.

This is what happens when you erect a "temporary" dipole with the first rope you find (don't look at the"knot"). Ten months later, the rope, burned by the sun and bruised by the winds, is about to snap. I may be off the waves while I replace it. I am not happy to have to climb...

Oh, and I brought a new straight key, one miniature key I bought in AliExpress. Much better than logging my good-old MFJ-550 on a piece of wood.

Today I activated peak EA5/AT-071 "Manzorrilla" for the 1st time. It seemed a leisurely climb, 1 km away from a main road, 161 m ascent. Ha! No path! Rocks, pines and bushes. Could stay only 1 hour → 18 QSOs (FM, SSB and some CW): Xiegu G90, DX-HF-20 whip+counterpoise. As to , I was very, very clumsy managing the mini pile-up in 14065 kHz. I apologize if I couldn't work all who called. All very nice and QRS for the newbie CW-er!! VY 73 ES TNX!

This morning I activated peak EA5/AT-099 "Serra Mitjana" for the first time. It was also my first time doing some from , very QRSs and with a rather bulky MFJ-550 straight key and a whip antenna. My contacts were very nice in slowing down for me!

I've had a conversation on the m17project.org/ reflectors from my phone, but I'm wondering if anyone out here has managed to pass this kind of traffic over the air yet. #hamradio

Broke the SMA connector in my . While connector arrives, temporary setup (photo). Recalibrated. Known SWR readings are now higher. My dipole used to have a nice 1.2:1 minimum around 14 MHz, now 2.4:1. Does anyone have an explanation?
