I've started monitoring 146.520 MHz as of late it feels dead but maybe i'll bring it back in my area

#146520 #hamradio #VHF

222 MHz Fall Sprint - 2025 Summary:
Total: Analog Qs = 2 Dig Qs = 6 Mults = 5 Total Score = 40

Tested a single loop antenna at ~30 feet as my other antenna was down for... maintenance. Heard a few weak stations when I first turn on the radio on voice but nothing too strong. Furthest contact I made was 132mi/213km away. All analog QSOs were made by sending the station a message on FT8 asking them to QSY to SSB. Thanks to all that were out there! #VHF #hamr

I wasn't in a summit or in a park, but still brought the HT to chase a friend on a peak. Two meter CW is a lot of fun!

#POTA DE-0618 Königsbrücker Heide (#WWFF DLFF-0141, #GMA DA/SX-230 Wettinhöhe) is a former military training area. When you climb the tower, you’re able to see the enormous size of it. There are two nice places to sit which allow you to put up decent antennas. Operating on #HF as well as #VHF and up from here is a blast. #HamRadio #ParksOnTheAir #Amateurfunk #qrp #mtr3b #morsecode #fm #hiking #mountains #Saxony

Fruits from our garden, tastes OK, smells incredible.

I have been monitoring VHF for almost two weeks now, heard no one, my CQ calls got no response. TA repeaters are on UHF and I have no high power UHF radios with me for simplex although the handhelds work fine.

I can also hear a Greek repeater but sadly they did not return my calls there either. :,(

Edit: spalling and gromar correctins

I'm still here playing radio on the ARRL September #VHF Contest. #6m and #2m were hopping this morning (although no Sporadic-E was detected here). Now, I feel like everyone has probably worked everyone else, the bands have gone quiet, and everyone's taking a nap. #hamradio

APRS DX map shows decent opening on #2m this morning but no one is on the air! #VHF

Getting ready for this weekend's ARRL September #VHF Contest! #hamradio

The universe always extracts a cost when you use magic, including radio magic.

Today I checked into my first net using solar power. 😎

AND I received my future #LinuxHardware from ebay, all convertible and stuff for portable #HamRadio operations. $175 for a clean used Thinkpad Yoga X1. 🤸‍♀️

But the battery is borked and the touchscreen doesn't work lol. 💔

Get in on these Windows 10 EOL deals yall!

IARU R1 VHF contest 2025
Band Mode QSOs Pts Pt/Q
144 CW 15 4852 323,5
144 USB 105 25564 243,5
Total Both 120 30416 253,5

The best was IP0A at JN40PQ 863km

The shack upgrades really made a difference to last years performance. The new Q5 transverter performed well. My only mistake was forgeting to mod my ts590sg to be able to tx on the whole vhf band hehe.

This was quite a successful #hamradio #amateurradio #amateurfunk weekend from our 86 m high local hill in #POTA park #DE0315.

I participated in the #IARU #VHF #Contest and made yesterday 50 QSOs. Today I was station sharing with @siwli and made another 15 contest QSOs. In total, I had 65 QSOs on 2m with about 15k points and reached 9 DXCCs and 31 locator squares. ODX was 658 km to F8KID.

RIG: FT-818 + homebrew PA with 40 W out and 4 ele yagi antenna.

(1/2)

Частота 145.500 на 2-метровом диапазоне оживает. Местный хулиган "ушел" в места не столь отдалённые и это освободило частоту. Утром включил и сразу RG2B, R2DBY, R2DRU и R3DDS на связи, несмотря на мою небольшую мощность. :)

#vhf #hamradio

Great idea for the #IARU #VHF #contest. As you know, I love maps...

It just misses a few photos to really put you in the field.

”The evolution of the signal generator during the sixties was relatively slow. A number of reasons can be listed to explain that. First of all, a lot of signal generators, perfectly matching the market needs, were already in the Hewlett Packard catalog by the end of the fiveties. The 606, 608 and 612 were state of the art signal sources for the measurement of RF, VHF, and UHF receiver performance of the time. The 610 and 620 series covered this same requirement for the lower to higher frequencies of the microwave spectra. All these generators were using vacuum tube or Klystron master oscillator, with High Q or cavity tuning circuits, whose fundamental design gave a guarantee of low noise and high spectral purity signal output.”

Итак, Антенна Yagi Ailunce AY04 для 2м/70см. Из минусов: отверстия крепления только под вертикальную поляризацию. А значит установка на металлическую мачту не подходит. Пришлось нарастить на мачте лишние полтора метра пластиком и тогда уже ставить.

По SDR в городе Жуковском (Дмитрию спасибо за его поддержку) проверил: сначала коллинеарной UVS-200 щёлкнул, потом - этой. КСВ можно хоть обмериться, а результат хочется видеть в действии. Разница между антеннами видна хорошо. 👍

Escuchando Rock Boulevard, con Mario Gallinares, como siempre #radiofutura #rf #91.1 #radio #fm #vhf

#lora #aprs on cheap #lilygo devices are lots of fun.

Now I wonder if I should try 2 meter #vhf but wonder where Lora chirps would fit in the frequency band plan...
