Re: EME on both 10 ghz and 23 cms

You will find most stations use windozzze, if you have trouble with linux, then dont keep beating your head on the screen, just run W7 instead.
Works fine, no dramas.

I am wondering how Keith is going, please let us know when you want a test signal via the moon.

Re: 2015 Winter VHF/UHF Field Day

Things are going well here fellas. I type this from a tablet thing sitting by a bonfire of logs and stumps etc, bands going from 6m to 23 then 5.7 and 10GHz. The others here have all bands up to 76GHz but they missed out on 24GHz due to technical difficulty. Its time to rest by the fire and we have ...

Re: F-Call thoughts

I think Colin has hit the nail on the head here regarding the incentive to upgrade. the costs are very high and having a waiver of this exhorbitant fee for 2 or 3 retries is a good idea. i was really surprised just how much it costs to get a licence these days considering i was told the marine radio...

Re: minikits PGA-103 LNA 0.05-3GHz

Yes, the pga103 is a good little device. I bought half a dozen from Minikits a while ago and put them in as the front end of a couple of 2m rigs and a tait vhf repeater and they really worked well. But ... they need protection on the input. Back to back diodes and a tuned circuit (or cavity) will ma...

Re: Summer field day 2015 - 10/11 January 2015!

You can work EMEwith a dish that size Damian A linear feed like a cavity backed dipole will work, but a septum would be better, and you would be able to work stations of 4 metre dishes or larger, provided you run 40 or more watts on tx. Ideally have a coaxial tr relay and a LNA at the feedpoint, ldf...

Great photos! But i am prompted to reply after seeing your generator set in the mt Bunyong pic. During the JMFD I was using a smaller blue generator of the cheap type and after working ok all night the next day it fried the laptop charger. Awful stink of the main electro leaking goo.

Re: Summer field day 2015 - 10/11 January 2015!

People go to great spots high on hills on these contest days. They take all the bands they can with them, Its a great opportunity to try and work these stations. Without these contests no one would go up on these high places and attempt long range microwave contacts (unless its a club event or your ...

Re: FT857D display zebra

I have worked on many 857's for add-ons, mods, and repairs, and they are a terrific radio. when 2 of mine failed with the display problem spending the money to repair them is well worth the investment compared to spending 1500 dollars or more on a different but similarly capable set. The part number...

Re: FT857D display zebra

Hi Bruce, in the case of the ft857 what you describe doesnt work There is no conductive rubber sheet on these and the lcd is directly bonded to the flexicable. No amount of cleaning will solve the problem , which is, that the drive chip is directly bonded to the lcd flexicable and it goes dryjointed...
