My SeaSDR_40 kit arrived from Italy. Last night I finished off building the kit together, the is rather easy to put together and the only real thing to watch out for is the toriod with the primary and secondary windings on it, to soldering it in correctly.
I also got the SeaSDR_40 working with Quisk by only having to make a couple minor alterations to the ~/.quisk_conf.py file.
near the top of the file I changed the hardware import
import quisk_hardware_model as quisk_hardware
import quisk_hardware_fixed as quisk_hardware
This will allow you to have frequency shown in Quisk based on the VFO of the SeaSDR_40.
To alter the VFO to that of the SeaSDR_40 change
fixed_vfo_freq = 7056000
fixed_vfo_freq = 7080500
All that is left for me to do is buy a metal box to mount the board into with some socket and connectors.

I have added a gallery of some the pictures I took while I was at Science Alive from Thursday to Sunday at the Wayville Showgrounds. Thursday was setup day for the 3 day event with Friday set a side for the high school children. I was a part for the Electronics and Communication, and Hackerspace stalls.
It was a great event and ran rather smoothly, we had a lot more interest in the Amateur Radio side of things this year compared to last year. and the Reprap 3D printers of hackerspace were a hoot with the public aswell.
This is a quick video of an AR Drone that one of the people part of our stalls bought in.
Last couple weeks I have a had a problem with my 897D doing double SSB on RX and TX. Last night I was looking around for a firmware update for the 897D to see if that might fix my problem as I have tried other things like full CPU reset on the rig etc.
Well I found the page below in my travels and it had reference to relay cleaning by hold down the UP and DWN keys and powering the rig ON will start the cleaning of the relays and display CLEANING RELAYS on the screen. The great news is that this little unknown trick to me has fixed my double SSB problem
As of the 1st of March the ACMA has permitted the trial of 1000 watt PEP for advanced licensed amateur radio operators, and this trial is to run for about 12 months where it will be reviewed by the ACMA.
As I primarily use Linux and I had to find an alternative way to program radios like Tait, Icom etc that have Dos based software to program them along with the need to have a serial port. Well after some trial and errors with various emulators like dosemu and wine, I found dosbox was able to do what I need to accomplish with accessing the radio via USB to Serial cable which you can buy cheap enough off of eBay.
Today was the first day of the 3 day Science Alive event at the Wayville show grounds. I was helping out on the ‘Radio and Electronics’ booth with Paul H, Paul S,(Amateur Radio Operators) and Robyn, and Jonathan from Hackerspace. It was a rather noisy day as it was school’s day, but… I was able to get a little coding down on my Arduino weather station and thanks to Jonathan for his help on couple my problems in my code. After the event finished at 1500 hours Paul S and I went over to pick up a Codan manpack to go on display at Saturday and Sunday at Science Alive. Overall it was a great day and I enjoyed the day
This is a coax switcher unit I made out of some parts lying around in the junk box. What I have done is modified an old ‘100 Watt CB antenna matcher’ unit and added an extra SO238 and a double pole switch to be some functional I can now use with my 2m/70cm setup.
Parts break down:
Metal box 51x51x32mm from JayCars be ideal, or bigger for more sockets
3 x SO238 panel mount connectors
2mm silver plated copper wire
double pole switch
