3A - Monaco - 31.07.14

Dear OM,
Activation of 3A on MS 70 Mhz (and possibly 50 MHz if there interest) next Perseid shower, August 12th & 13th, is hereby confirmed.
Hans ON5AEN, who has MS experience on 2m,  will join to operate the station.
More info - like frequencies, sequences etc - will be released later.
Meanwhile, already prepared some theoretical range prediction. As you are probably aware, Monaco is only 3 kms long and 300m wide, with mountains towards the north and west... not the best place for a low take-off angle!
According to our spot where the station will be set up and the models, we expect a range like depicted on the map you can download here - so you can already check the possibilities to contact us.

Quadruple Watch!

by Marco, IW0FFK.

 

Last week I’ve bought a Kenwood TS-590S, a modern rig with 32bit DSP IF filtering features.
I was especially interested in the NB2 function that seems to be effective in reducing the impulsive noise with variable frequency, like the noise produced by many poorly filtered devices that surround the antenna if you live in a city.

 50 MHz high dynamic and low noise RF preamplifier

by IK0VAQ - Alessandro

 

The preamplifier I’m describing is used as external device and drives a signal splitter for a secondary spectrum receiver (eg. Panadapter, SDR receiver etc). The performance of the device adopted, the Minicircuits PGA103+ Monolithic Amplifier, are very interesting mainly for the high dynamic range. The very low noise is not a big issue on Six Meters band but is still a good thing to have.

The overall gain, included the 6 dB attenuator on output, is equal to 20 dB with a NF on 1,5 dB (0,5 dB of PGA103+ plus 1dB of input filter loss).

IARU Reg 1. - South Africa 2011

Disponibile qui il nuovo Bandplan 50 MHz 2012 in italiano!

 

Ad alcuni giorni dalla fine del meeting sono disponibili i documenti - ufficiali - finali - dell'incontro di Suncity in Sud Africa; ecco il link per scaricare il file dal nostro sito o dal sito della IARU.

 

Cosa cambia per ciò che concerne i 6m? Non moltissimo. Come buona news c'è l'allargamento della banda CW assieme allo spostamento della banda beacons. La finestra intercontinentale (50100-130) è stata salvaguardata mentre è nato un "settore" il cui traffico dovrà essere "prevalentemente" internazionale. Questa ultima "nota", benchè molto ambigua lascia ben sperare per futuri sviluppi "anti qrm" (alcuni paesi già stanno adottando questa raccomandazione ma ne parleremo in seguito.

In attesa che si disponga un Banplan nazionale (limitato cioè alla porzione italiana 50-51 MHz) pubblichiamo - in anteprima assoluta per l'Italia - la prima versione (tradotta in italiano) grazie al lavoro del gruppo Sixitalia.

 

BANDPLAN IARU 50 MHZ 2012 IN ITALIANO


English version

 

After some days is now on line the final documentation of august IARU meeting in Suncity (South Africa). Look for the final documents in our web site or in the IARU website.

 

20 May 2011

You can download the documentation referring (also) some proposed 6m changes here and here.

One of the worst proposed thing is to move the Intercontinental Dx calling frequency and reduce the Intercontinental Dx window at only 20 KHz. :-(
