    Dear listening community, what are your thoughts about the Malahit DSP2 radio ? And compared to Belka (DX model with of course reduced freq range).Besides wide range and NR that is said to be great, what would you say about the product ?(Informed already on the origin of the product, speaking tech only)#swl #shortwave #shortwaveradio #malahit #belka #sdr #hamradio

    Well, that was a first.

    @qrper mentioned in his recent video how some hams like to make antennas.

    The prototype worked well enough that I'll proceed on to another iteration. Leaning it out with two legs held up by the radial wire worked well, and the little knobs on the top of the spool to hold the wire in place work fine. I'll made them a touch larger to be more robust, but the concept works.I want to be able to fit 12m of wire on the spool, because I want radials that work well as flat radials on 40m, which might take up to 28%λ instead of the nominal ¼λ which would be appropriate in the "discone" setup with 45° radials. However, with this wire, 8m barely fits on this spool. So I need to add a generous allowance for more wire.I need a handle for the hub at the bottom so that I can wind it up with the legs removed. It's unwieldy with two 6' long fiberglass stakes.According to DJØIP, 1 elevated, tuned radial is roughly equivalent to 8 ground radials. Two of these should give me the performance of 16 ground radials. According to his table, I can expect 3.76dB gain over my usual 4 radials on the ground, or even more if I'm using a shortened antenna.With these just leaning, if someone inadvertently walks into my bright pink wire, they'll probably just knock over the leaning posts, which is unlikely to cause a big problem. I'll probably use bullet connectors for the other end of the wire so that they can pop out and not knock the antenna over.

    We had a surprise opportunity to go to the beach this weekend, near Southport NC.

    We had a surprise opportunity to go to the beach this weekend, near Southport NC. I have the weird preference to sling my hammock under the house, between the clotheslines, instead of sleeping indoors. Half camping? I use a big rubbermaid box as my "suitcase" and put my shoes on it overnight... It was cold at night, but an underquilt and reflecting bubble insulation in the hammock, with an inflatable mattress on top of my down sleeping bag, kept me cozy.My wife and I went to Fort Fisher State Recreation Area and set up a pair of #HamRadio transceivers. Because this weekend was SSB CQ World Wide DX contest, she couldn't find an empty space to call CQ, and had trouble breaking through pileups, so after a few QSOs she decided it wasn't fun any more and read a book. It was not the CW CQ DX contest weekend, so I successfully activated US-3842 with Morse code. Then back at the beach house, I kept ducking out onto the porch to hunt #POTA operators using CW, with a 33' random wire antenna hanging from a spiderbeam pole, connected to the 9:1 port on my tiny little homebrew QRP dual-port unun. One of those QSOs was with the ham who sold me my KX3 that I used to make the contact! 🎉I gave the random wire a workout with QSOs on 40, 30, 20, 17, and 15 meters. Tried hunting with no luck on 80, 12, and 10 meters.The wind eventually broke the antenna wire off the terminal, so I'll want to fix that before going out again. But at the beach, it was easy to bodge that by stripping back a bit of insulation and screwing the bare wires in the terminal.
