Hill Fort Communications


#1

I guess the Torches were not battery powered (well at least not 2,500 years ago).

In reply to G0LGS:
Hmmm…
I wonder if that would count as a SOTA activation if the torches were used to flash the message in Morse?!

Yeah why not, i heard on the ICQ podcast that some amateurs in VK used red light to set a distance record from a hilltop!!

UPDATE, Ok so i cant find the VK guys, but i did find a link to some UK hams also using light for contact

Frequency = Other (Lightwave)

If that is acceptable can I Yodel from Moel Famau to Foel Fenlli for a summit to summit?

Frequency = Other (Soundwave)

In reply to GW7AAV:

Got to be an EM wave which sound isn’t!

There are people playing with cloud bounce LED and laser signals working paths of several hundred kms. There were some articles in DUBUS a few issues back about it.

Sounds ideal for Scotland, although it’s quite sunny today after the cloud touching the snow most of yesterday.

Just wondering how I’d work cloudbounce when on most activations I’m actually in it. I don’t think it will catch on for SOTA… at least within 100km of where I am activating!

Now raindrop scatter is perhaps another matter…

Or we could dispense with all the tiresome technology and give telepathy a try…

That would be a darn sight lighter to carry up the hills!

That’s meticulous advance planning for you. It does rather commit you to certain days, whatever the weather. I am now following Jimmy’s preferred MO of fairly last-minute plans and decisions, that generally work in allowing us to walk and activate in decent weather.

This sort of planning is not so good for booking accommodation though.

Now there is an interesting way to get out further with a handheld rig!

Here is another example of light communication from forts, this time using CW.

How about a handheld tied to a helium balloon with a very long lead to the speaker mic?

…Or something I always wanted to try; A dual band handheld set in cross band repeater mode tied to a balloon or kite with another at the bottom using on 70cms.
