Have you ever transmitted right by sea water? Give yourself another 10dB. That is 10 times the power! Let’s quickly have a look! Callum.

An amazing 24-month journey in 5-minutes. You guys and gals have been incredible. You will ALL go down in history as being part of a fabulous group that created an amazing business, a community and most importantly, friendship. Thank you, Merry Christmas, Seasons Greetings and let us look forward to a fabulous 2023. 73 Callum, Wendy, Loki and Emily. X

We’re live on HF again. Join in, chat, or listen. Just having fun. Usual frequencies, from 80m up to 10m.

We have a panel of judges PLUS *YOU* to decide on the BEST SIX entries for this year’s emergency / scrap vertical antenna challenge.

When *only* WRONG ANSWERS will do! Join us for fun and frivolity with Mike M0MSN, Mike K8MRD, John NZ4J and myself 🙂

Here is 6 ideas you can try over a holiday. Radio Direction Finding via KiwiSDR, Try sending an email over HF using Winlink, Have a go at some old digital modes, PSK31 or maybe MFSK16, try some new software – maybe FLdigi or Ham Radio Deluxe? Lots of people ask about the software I use on Fridays, it’s N1MM. HGave a look at that? And finally, give yourself a challenge of getting on a new band or maybe at least 1 QSO per day? What ever you do, enjoy! Callum.

I’m LIVE on HF. Let’s see who we can say hello to today. Join in, call me, follow the chat. It’s all just for fun. Antenna is 12.4m Signature. Logging is via N1MM+. On TV is the GeoChron. Amplifier is Acom 2000. Radio is TS-990s. Left ear is normally my transmit audio and right ear is often a dedicated RX antenna. Sometimes I switch it around. You MIGHT end up with left or right ear occassionally if you are using headphones (recommended).

No talking video. Watch me make a doublet antenna for a ham radio start to finish. Using 450 ohm balanced feeder, DX50 antenna wire and a custom doublet centre available from my shop.
Faster 10-minute video currently under edit. Will sort out soon.

Just search Google for "dx commander doublet centre" and you’ll find this.

Callum.

Fancy a quick blast on HF? See what the bands are like!

Years ago, I attended a presentation that Nigel (SK) G4NRR gave. He explained that dipoles resonate on every other harmonic and full wave loops were resonant on every harmonic. These extremely basic rules are the fundamental build blocks of almost every antenna I build. See what you think. Callum, M0MCX.
