Re: Please Mr ICOM I would like a IC-910 replacement

Yes I'd like a "IC-9300" as well but suspect as Adam has pointed the ROI case will need to be bullet proof! The IC-9100 is a fairly recent release they would still be paying off the Yen invested in that, all new medium to high end transceivers will be SDR from now on so it will happen but maybe not ...

Re: What's on your Workbench?

Hey Tim

The graphic equalizer on the boom box seems to be set for a optimal mid range audio pass band, is this part of the Raspberry Pi SDR experiment?!!!

Re: What's on your Workbench?

Very good signals on 47 GHz from Iain over 32 km, interestingly when a heavy rain band went between us nearly -20 db drop in signals but still readable! 20160605_140437.jpg The two 47 GHz systems, BTW the system on the right is the 10 GHz EME system. 3 initials yesterday on 10 GHz JT4f EME (G3WDG, O...

Re: What's on your Workbench?

Hi Ben,

Just google "I3OPW" and go to the "47 GHz mixer", uses MA4E1318 Anti parallel diode usually -7dbm per sideband on 47 GHz output. Alternative if you like gluing diodes that are 0.6mm x 0.3mm to PCB's google 47 GHz & DL2AM ;-)

Re: TO92 LDO adjustable positive voltage regulator

Hi Allan TO-92 Adjustable LDO's are rare/non existent. A few LDO's with the usual multiple packages (including TO-92, LM2931xx is one) that have both fixed and adjustable versions only list TO-92 being available as fixed. I use AMS1117ADJ's in SOT-223 package. Slightly bigger than TO-92 but suspect ...

Re: VK3UM Silent Key

Very sad news. Doug will be remembered for many things great on VHF and above. From his days on 6, 2 & 1 metres in the 1960's as VK5KK in Adelaide, to Darwin in the mid 1970's as VK8KK right through to his activities in the last few weeks. And for Doug for allowing me to pick up his old VK5KK callsi...

Here is a photo from the tech night at EARC a week ago with mods on a few panels.

Hi All. A good field day, great weather didn't get as hot as predicted. Even had time to Road test the Geelong Club 3400 MHz "patch panel" project transverter. 2016_Summer_FD.jpg That's it in the centre on the camera tripod. Easily achieves 1 Watt output. The noise figure must be pretty good (I've b...

Re: 3.4GHz QSO Party - VK5 Chapter

Hi All,

As about 40 of those panels found their way to VK5 (SCARC & EARC) the VK5 "Chapter" will run a parallel QSO party on the same day (21/2/2016), same times, frequencies, etc.

Coordination frequency = 439.925 MHz VK5RAD Crafers Rpt (North & South)

More as it happens :-)

Hi Mal

We need to enlist a video guy next time, maybe get the ATV group involved?!

Here's a short video of the 47 GHz contact :-)
