Taken at New Year, the countryside looks lovely covered in snow! So cold though that I have had to create a 'Winter Shack'! Click for more Winter photos |
Jabra A210 interface to connect a bluetooth handsfree headset with my FT-747 transceiver. Click for more info |
I have a neck condition and so rely on a bluetooth headset for most of my phone calls. I came across this article by K7SFN where a bluetooth headset was connected wirelessly to his transceiver so he could move around and rely on the transceiver's VOX control to switch transmit/receive. He used a Jabra A210 device which was developed as an adapter to provide bluetooth flexibility to non-bluetooth mobile phones. Unfortunately it's no longer in production and I had some difficulty acquiring one. I had to buy mine in the US and have my friend Joe forward it on to the UK for me.
K7SFN's article puts it very well and mine was a very straight forward project. The device has a 2.5mm stereo socket for mic in on the tip and phones out on the ring with sleeve to ground. As 2.5mm is a faff to solder, I used a 2.5mm-3.5mm adapter and then a 3.5mm to RCA Phone lead to give me two leads. I put a Yaesu mic connector on one lead and a ¼ inch jack plug on the other lead and amazingly it worked well first time as I tried to contact a station in Cyprus, another in Iceland and a nice audio report from a special event station in Portugal! That's fine using my FT-990 but my micro-shack has a FT-747 with no VOX so the next step was to build a VOX circuit!
Before Christmas, the Micro-shack in my Dining Room was first revamped with a T/R switch to switch PTT on the Mirage B108 linear amp and the Icom IC-2E at the same time. It also steps power down to 9v from 13.8v for the Icom. This was then revamped again to be a complete HF/VHF station - the 'Winter Shack' which comprises the 2m equipment, FT-747DX HF transceiver, homebrew 6m transverter and linear amp, homebrew Z-match ATU and Datong RF-Clipper!
My 20m vertical loop antenna has shown itself useful on 6m too! It is selected by relay control at the bottom of my garden. The
relay control is all thanks to Tony G0DLX and pictures can be seen here.
I was hoping to build the Minster SSB transceiver from Walford Electronics but sadly Tim Walford concluded that it's design would make it too expensive to sell so the soldering iron is hot and waiting at the moment! I do need to give the Sutton DSB HF transceiver that I built some years ago some exercise so perhaps will in the near future!
