| 2025-03-09 13:39:00 | ian@mastodon.radio | 15 | Working on it... | I have some big car battery clamps that will be ideal for HC12 "Make a contact using an unusual antenna". The other end I have terminated with PowerPoles, so the question is... Do I chop this, or do I make an *extremely cursed* PL-259 to PowerPole cable?? |

How far can two Yaesu VX8-DR HT’s communicate on L1 (20 mW) transmit power with dummy load antennas? Turns out the answer is about 12 feet on UHF. Was surprised that the shielding was that good…SuccessfulTwo-Way QSO (N8DMT & N8DKK)446.050 MHzL1 (0.02 W, 20mW)Distance ~10 feetSquelch Level 0 (open squelch)Antenna: SMA to BNC-F Adapter with DIY BNC-M dummy load#HamRadio #DummyLoadComms |

| 2025-03-22 17:40:47 | ian@mastodon.radio | 15 | Working on it... | This week is "unusual antenna" week for the Ham Challenge. Sadly despite my best efforts this afternoon I was not able to manage a contact using either my rotary washing line, or a literal wet piece of string, but I had fun trying!The full write-up of this, plus the previous three weeks' challenges, is here: https://ianrenton.com/blog/52-week-ham-radio-challenge-roundup-weeks-9-12/HC12 |
| 2025-03-23 21:51:07 | DC4LW@social.darc.de | 13 | Success! | Just had a look on the website and found out, that my HC12S from three weeks ago did not count. It seems, that the bot can count one week number only. But I already completed this challenge in https://social.darc.de/@DC4LW/114093167045604116 😄 #hamchallenge |
| 2025-04-01 16:36:35 | pg4i@mastodon.radio | 10 | Success! | #hamchallenge HC12SToday I made a QSO with an unusual antenna (Nigel M0NGN on 7 MHz). It is a linear loaded vertical with 2 radials. The radiator is 7 meters long and consist of 450 Ohm ladder shorted at the top. This runs along a 10 meter Spiderbeam mast, so the feed point is at 3 meters high. |
| 2025-04-21 17:53:57 | df5go@radiosocial.de | 14 | Success! | My only fixed HF antenna is quite an unusual one. It is an inverted Vee, but with an angle of only about 60°. The feedpoint is on a window at the roof ridge. From there, two wires (about 4.5 m long each) go down to the edges of the balcony's balustrade which is incidentally also about 4.5 m wide. So the legs of the antenna basically form two edges of an equilateral triangle.#HamChallenge #HC12S #amateurradio #hamradio #amateurfunk |
| 2025-04-21 18:01:58 | df5go@radiosocial.de | 14 | Success! | Combined with an manual tuner I am able to work with this contraption from 30 m to 6 m. To comply with regulations regarding RF safety and to avoid interfering with neighbours' electronic devices I transmit with only 5 watts. But with this antenna I am still able to occasionally work DX stations in both CW and SSB.#HamChallenge #HC12S #amateurradio #hamradio #amateurfunk |
