Callum,
Yes I can tune the H,Sierra to 80m (tunes across all bands). We are on the boat from Saturday through the comming week. Unfortunatly its going to be the last week as the boat is now up for sale.
We have spent a fortune getting it ready as our retirement home (compete refit) hence the fit-out for radio. Wind genny, solar panels etc but thats another story.
Yes we can try and arrange a sched one night next week say Sunday or Monday. I will ring (your number as above).
As for the technical aspects I have experience of working from a small island as VP8CEO and the sea water gave a good boost to the signal (even out performed the military equipment with a cut to length wire) so I thought here I have a sheet metal platform sitting in water and electrically connected to the water by a big zinc anode at the four corners - could it work like a ground plane?
The first time I fired it up last year it was like the other phase of the sunspot cycle, wow! VK’s ZL, VE, States, and europeans stations so I tune around and hey ho a pile up! called my last two a couple of times and was in! moved on and tried a state side call confused him completly trying to explain what a narrow boat is. And all this not far from the bottom of the devises flight.

It works but dont tell everyone they will all want a piece of the action :)

Till Sunday or Monday
Martin

Hello Martin and Thanks for your encouragement. I must say that from the 6 or so quick test QSOs I’ve had, I believe you may be correct in your efficiency assumptions. I have a feeling that canal water is a better ground plane than most people think. My (military) Signals friend agrees with us - however the ham community are still dubious.

Of interest, I’m firing my AL-811 amp up on Friday night with James (M3YOM) for a 40m test. Be assured, I will compare 400w on my 811 to my puny 100w as and when we capture some DX. I’m used to VK and ZL when I work long shifts on my vertical antennas on 40m so I hope the DX gods are with us. So far though, the experience on using radio on canal water has been most pleasurable.

I wonder if there is genuinely better efficiency between your High Sierra and my 8.5 meter vertical. I bloody hope so with the extra costs I’ve gone through! :)

Can you dial in 80m? I fancy an 80m “narrowboat” net in the Summer - we’ll be on the boat for most of August. Gawd knows what time of day would be best though and a vertical would be the worst antenna to use! I did an experiment in making my vertical a sort of inverted Delta loop / inverted L (pulling a wire back to the tiller from the top of the vertical) which made it slightly better for NVIS work. Proof of the pudding is in the working though. Sometimes on 80m, you just need some horsepower. Hence the 500w linear requirement.

Shame 40m is so awful these days, I used to have lots of laughs on 40m - on low power too.

Cheers-n-beers,

Callum

Callum, I have an IC706 paired with a High Sierra side kick (the same as W&S sell)I brought second hand in the USA complete with the optional 2m whip. It’s fitted to the centre of the boat roof (50′ narrow boat) and the performance is brilliant. I can work the DX through the pile ups.
Off the boat its a good set-up but on the boat its superb!
Do you really need an amplifier?

Hello Lin,

You guys have a boat? You should drop me an email. Where are you moored?

Cheers, Callum.

Hi Callum,

We should talk! Ian (G8PWE) and I are keen canal enthusiasts, how about a ‘run out’ and test the radios mobile?

Hello Chris. Yup, IO91bx! Silly me. Sounds like most people put their brave faces on and had a ball regardless. Cheers-n-beers. Callum.

Good report as always. Conditions were rubbish both prop and weather, but we had a lot of fun. Re the locator surely you mean IO91BX, unless you were in Alton Towers HI.

I enjoyed reading your report on VHF NFD 2008. The lowestoft District and Pye ARC havent participated in a vhf nfd for years so glad to put it on this year and thoughly enjoyed it even with a few minor problems with the equipment.

The 70cms beam you were using is a jaybeam multibeam as we were using the same type you can also add more sections to them to increase the gain.

best wishes

Really? I didn’t think lack of use closed a repeater. I did think that being an arsehole was a reasonable excuse though :) However, under that regime, I would have been closed down many years ago - ha ha!!
