I’d like to wish you all a happy holidays and happy new year for 2013. Please take care, and enjoy your great hobbies.
Last night the 19th Dec. the EARC had its tech night at The National Military Vehicle Museum at Edinburgh Parks and here are some the images from the night Crystal Receiver judging. The prize was donated by Aztronics which was a solder fume extractor that was won by Chris VK5ZST.
I also like to give a big thanks for Paul VK5VCO who arrange the crystal receiver comp, the prize, and the doing the judging. Also a big thanks to the Military Vehicle Preservation Society (MVPS) for the Museum tour and venue for the crystal set judging. And also big thanks to all that entered comp and turned up for the night.
Enjoy the pics I took from the night
If your interested in testing the at accuracy of you your transceiver on 6/2/70/23/SHF there are beacons setup in around Mt Lofty (VK5VF) and the Elizabeth Water Tower (VK5RLZ) which you can listen to and they are on the following frequencies
6m = 53.3200 GPS locked
2m = 144.4500 Crystal locked
700mm = 432.4500 GPS locked
230mm = 1296.4520
SHF = 2403.4520
SHF = 3400.4520 proposed
SHF = 5760.4520 proposed
SHF = 10368.4520 proposed
SHF = 24048.4520 proposed
The GPS locked beacons accuracy will be in the order of 1000th of a hertz
Yesterday my Softrock RX Ensemble II HF Receiver arrived from Five Dash Inc. in the US within ten days and was very well packed. Any way like most grown men with a new toy I descided to take the day out and build it, the took me about 15 hours in total. The guide by WB5RVZ is comprehensive and easy enough to follow in a half dozen so steps. I also have a nice box for the Ensemble II RX coming from the KM5H store and it will make it to be a nice looking package.
Here are some pics from the build
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.
Bus 001 Device 005: ID 0cf2:6250 ENE Technology, Inc. SD card reader (UB6250)
This card reader uses the ums-eneub6250 module and needs firmware to operate correctly which is currently not included in the Debian firmware-linux or firmware-linux-nonfree packages.
The way I have gotten around the problem at the moment is to downloaded the Ubuntu linux-firmware package and extracted the deb package to copy the directory ene-ub6250 from the extracted directory /lib/firmware/ to /lib/firmware/ on my working system as I not wanted to install 40 odd megabyte of other firmware I not needed.
After moving the files over run the following and all should be ready to use
# depmod -ae
# update-initramfs -u

As testing goes on, the .asoundrc file is getting more complexed in its setup. This is where we are up to now, we have 2 profiles going for ‘local’ and ‘DX’ and we select between the profiles by running in terminal
$ arecord -B 12000 -D local_eq_ -r 44100 -f S16_LE | aplay -B 12000 -D ladcomp
$ arecord -B 12000 -D dx_eq_ -r 44100 -f S16_LE | aplay -B 12000 -D ladcomp
And now for the dreaded .asoundrc file.
This is an update of my prevous post
VK2MEV and myself have been working on better compression and equilisation to use with the FT-857D and our hardware. we have since changed from swh-plugins to the plugin we are currently using is the tap-plugins which seems to do compression and equilisation a lot better that the latter.
These guys must be absolutely nuts, or very well paid, or both. either way great video of a tower climb.
