SOTA - Good Friday G/LD-011 High Street

Sun, 03/04/2016 - 09:53 -- morganrushton

Easter Bank Holiday weekend. Weather forecast looking almost as grim as the anticipation of impending doom of tackling some DIY plumbing in our kitchen at some point - apart from Good Friday, which looked half decent.

Knowing I'd be awake at the normal 'weekday alarm time' (or a little earlier) we planned to make the most of the best day (weather-wise) and get out in the hills. I packed our gear up after returning from the club on Thursday night and started looking for a suitable summit to activate.

Aerial Changeover Relay Project Build by David Cutter G3UNA

Sat, 05/03/2016 - 16:54 -- davidsilkstone

Posted on behalf of David Cutter, G3UNA. (Chairman, Ripon & District Amateur Radio Society)
Mainly for radios without a separate RX aerial input. This is the simplest and smallest version. I chose to use the relay that W6PQL uses on his projects: see his website www.w6pql.com which has many other fascinating projects.
The W6PQL method was used to improve isolation - see circuit diagram picture.

Pixie CW QRP 40m Kit

Thu, 03/03/2016 - 17:37 -- davidsilkstone

The Pixie is a well known and very good value 40m CW QRP kit. I used it as a build project during my Intermediate studies in 2015. I’m certainly no CW / Morse operator, but it was interesting to construct and it worked!
Pixie operates on 7.023 MHz, with such low power (<1W) you can see that the “dummy load” supplied is adequate just being a resistor.

UKAC - why bother?

Yes we can roll out loads of excuses.
"There's no-one on VHF SSB any more" which is partly true after all licencees were granted access to HF, but no real reason to leave it out altogether. Some new rigs are able to do VHF and UHF multimode, and it's something you could do - right?

Antenna woes

Sun, 29/11/2015 - 15:43 -- andyripley

It was last Monday night. The receive signal strength of GB3HG wasn't its usual full set of bars on the rig and I wasn't getting into the box very well. It had been very wet, so I'd assumed my coax (of unknown vintage) had finally died.

In the hills again - SOTA Activation - G/NP-010 Pen-Y-Ghent

Sat, 17/10/2015 - 09:30 -- morganrushton

I managed to activate Pen-Y-Ghent last weekend whilst out walking with friends. My first attempt to activate the summit earlier in the year using my Baofeng UV-5R on 2m came to nothing and it's been niggling me ever since.
One thing I've learned about SOTA activations is they don't always go to plan, the last time we were in the Yorkshire Dales on Ingelborough we had to abort due to an electrical storm (we'd actually made the summit and I was about to set up when a rumble of thunder had us scurrying off the top heading for lower ground).

Cancelling those excuses

Wed, 14/10/2015 - 17:23 -- andyripley

There's something to be said for a sunspot minimum, or upcoming one. You could of course just expect to not make any contacts on the higher HF bands for a few years and mutter on about not having the room for low band antennas etc.
There will be the occasional contact on such as 10m and 6m but having modes other than F-layer propagation, it's just that you may have to put the thought of getting VK or ZL on the back burner for a while. Maybe the odd hop into Europe, but no real DX perhaps.

Antenna Surgery - Saturday 3rd October 2015

Sat, 03/10/2015 - 14:24 -- morganrushton

A few club members popped round to help Mike G4IUF sort a few missing elements on his beam this morning. Big thanks to Mikes XYL for the refreshments and to David G3UNA and Roy 2E0RHH for helping out.
I'm sure we'll have a full explanation of the beams characteristics on Thursday at the club. In the meantime have a browse of the images from this morning - now there's an mast many of us dream of owning one day!
 
 

N1MM+ 1.0.5210 Undocumented feature!

Tue, 22/09/2015 - 21:22 -- andyripley

If you're on Windows 7 and N1MM+ says there's today's latest version of it's logging software - DON'T DO IT.
It loses the port numbers, so it doesn't connect, it just gives whatever port numbers in the list it thinks it has, not the one that's actually used to connect to the radio.
Stay on an earlier version and resist the idea of updating. It's not the computer as HRD works just fine on COM4 but N1MM+ doesn't show that port here.
N1MM+ doesn't appear to have a "report a bug feature" on their website.
The "non-plus" version works fine here.
