Michael Meerman’s (M0MPM) amazing QSL card page is now live on RADARC.org!

After some hard work from Michael M0MPM, Tom M0LTE and our web team, we are happy to announce that there is a live QSL card viewing system for RADARC (M0AAA,MX0AAA,G3ULT, G3AKF, M4T,M0EEE).

There is a vast amount of cards to see and one can search, browse or just sit back and watch as a slide show.

Antennas evening 14th June, 50MHz UKAC

Folks,

We meet again this Thursday 14th June.

Venue: Reading Rugby Football Club, Holme Park/Sonning La, Sonning, Reading RG4 6ST 7pm til late.

This time we’ll have a go at the 50 MHz UK Activity contest. Aim will be to introduce people to contesting. It runs from 8pm to 10:30pm BST. There’s also a 50 MHz FM contest from 7pm to 8pm before that for the really keen. I for one would be at least interested in giving some points away in that.

We will also try and do a bit of an RF site survey at RRFC just to get
an idea of how noisy/quiet it is. So I’ll bring up some SDR kit
(software defined radio) of some sort – probably an airspy and SDR
Sharp.

We will have some sort of HF station also. I think Wally wants to
experiment with a 20m/40m cross dipole. Not sure what he did to upset it.

I’ve not run this by the committee yet but we might have a look into why the cheapie icom club rig we have is deaf as we established last time. It’s not much use as a rig at the moment so we might as well learn something from it. I’m thinking for those who wonder “what’s in the box” it might prove of passing interest.

As ever feel free to bring along anything you feel may be of interest.

Looking forward to seeing you there.

We will adapt activities (QSY the bar most likely) if the weather is not clement.

Refreshments provided by the bar!

Podcast about Understanding Receiver Specifications

Thought the following Podcast might be interesting to members:

https://www.hamradioworkbench.com/podcast/understanding-hf-receiver-specifications

Eric Swartz WA6HHQ, co-founder of Elecraft, joins us to guide our understanding of RF receiver performance specifications. Eric introduces us to common receiver specs such as Sensitivity, Noise Floor, Dynamic Range, Intermod Dynamic Range, Phase Noise, and RMDR. He tells us what they mean in real-world receiver performance terms, how they are tested, and whether it’s better to have a higher or lower number in each one. It’s also the final episode before the 2018 Hamvention and George and Jeremy share our plans for our Booth, special offers, and exclusives for show listeners who stop by booth 3104 in Xenia.
