22 Meter Band HiFER Beacons / 450 ohm ladder line

« on: September 15, 2018, 1343 UTC »

I posted this on the LWCA message board as well...

Currently on my antenna, I'm using a an inverted-V fed with good coax. However, as with almost all coax, there is some LPF (loss per foot), and with a 4mw output, that could result in pretty substantial loss at the end.
The transmitter is approximately 50 feet or so from the antenna at this time, and will remain at that distance with the new setup, however, I am looking to use 450 ohm ladder-line as opposed to traditional coax.

Is anyone else using this method, and if so, what kind of improvement in signal (if any is to be had) are they noticing?

22 Meter Band HiFER Beacons / antenna update

This has been the first full day of transmitting for the DNU beacon and I am proud to say it has been running well!

However, the inverted V that I built has been giving me a tough time when getting swr measurements as it does not stay consistent throughout the day. This morning it was 1.5:1, this afternoon it was close to 4:1, then later in the evening it was back down to around 1.7:1.

Not certain what's causing it, I will continue to keep an eye on it. The comet analyzer i'm using probably isn't lying to me.   


Anyway, i'm very much looking forward to any reports people may have about the signal. 73 for now!

22 Meter Band HiFER Beacons / DNU hifer beacon

Good afternoon! I finally assembled the amazing Black Cat Systems 22 m beacon and have officially placed it on the air as of 16:24 utc, 09-03-18

The frequency is approx 13.561.6 and the callsign is the suffix of my amateur call, DNU.

I will be attempting to keep this on as full time as possible.


I would love sone paper qsl reports, but digital is FB as well.


73, Adam.
