A new software package for Windows from Simon Brown (G4ELI) is slowly emerging. Everyone should know Simon for being the original author of Ham Radio Deluxe, and most recently his superb SDR-Radio package: sdr-radio.com (currently as I write this the SDR server appears to be down?)

The new software is called Simon's Greyline and is a FREE download without any restrictions.

Latest version is Build 157 and is available from http://www.dit-dit-dit.com/Downloads.aspx

As I said before the software is"slowly emerging", so I expect more modules and additions to appear over time.

Here are screenshots from my system which the software allows you to produce via a press of a simple Icon at the top of the main Toolbar.

Currently the main screen shows a Map with Greyline and QTH info, with optional side panes, clock, solar data and geomagnetic data windows to the main display. Different configurations are available, you will just have to have a play around with what suits your mood.








From the top of the Toolbar there is a sub menu marked "More" which will then call up three other graphical sub screens via their seperate Icons.. Geomagnetic indices, Solar Data, and Sunrise & Sunset as below:

 
Geomagnetic data




Solar Data







Sunrise Sunset



This is a great addition to the shack desktop, for those who require up to date Sunspot and Solar flux Data. I currently have it loaded on a Windows 7 (32) package, but I expect it will work on XP and anything upwards without any problems.


Give it a try and have a play and see what you think?

My resistor supply was getting a bit low, so I found a great deal for 2500 pieces, 50 Value kit, 1/4W 1/% Metal film:





Infact the price was so good, I ordered 5000 they arrived  here in less than a week direct from China.

The wife won't let me have one yet, but the video is well worth a watch and you may go and raid your piggy bank afterwards?:

I have been thinking about this for sometime, after some Ham friends and others have said to me "Steve you have good ideas at times and find some excellent search's for us Amateurs why don't you write a blog? You have been feeding others with the information for years" True I have made some excellent friends like Roger G3XBM http://g3xbm-qrp.blogspot.co.uk/ via his great blogging exploits and  QRP projects, along with Hans PD0AC's radio antics http://hamgear.wordpress.com/ . I don't expect I will write things to the same high standard as these pair for a while, as I do not have the time at the moment, but I hope I will make some sort of valuable contribution to Amateur radio over the years..

A bit about myself, I have been licenced since 1984. I never went to a RAE course, I just read up a few books on the subject like the Radio Communications Handbook http://www.rsgbshop.org/acatalog/Online_Catalogue_Technical_6.html#a1426  armed with this info I walked into Cannock Chase technical college, and came out with 2 passes after nervously waiting for a few months for the results.. Not bad I thought? Of course I had been interested in radio since the mid 70s when I built crystal sets, and worked in the local television shop on a Friday after school and all day Saturdays. Along with the school radio club,  backstage lighting productions and the local drama club Rugeley players, I carried the knowledge forward and got some sort of career out of it and worked in the trade at Thorn EMI Automation's Test dept for 14 years or so..

Since 1984 my main Amateur interests have been largely around VHF/UHF and some 50MHz operation, using a Yaesu FT-736R. Nowadays it is small HF QRP projects (when I can find the time to construct).  Some may remember me from the AX25 Mailbox (GB7RUG) I ran for over 5 years,  I built it myself from converted ex CT2 units for the TNCs, and Pye PMR M & MX series radios for the radio ports, along with a 386 PC running DOS and FBB mailbox software on top of a G8BPQ node switch  package. It certainly was  full of fun and stress with 60 users at its peak, mail forwarding South to GB7COV via a 70cm link & North via a 4m link to GB7NOT. Fully operational 24/7 Serving Mid Staffordshire Radio Hams, it never failed once!  I retired the BBS at the end of 2001, I felt it had run its course with the Internet now in full steam..
