Gday Phil I am using the VK2AES Cavity Backed Dipole - Dish Feed Andy (VK2AES) presented his cavity backed dipole design at Gippstech in 2007, it’s an efficient feed designed for an optimum f/d ratio of 0.35 and is relatively straight forward to construct using copper sheet and copper and brass tubi...

Ben just to add to my previous entry , I had a talk to mark from minikits this afternoon on another matter and asked about your question he said the 3.4 ghz module will run at 2.4 ghz but at a reduced output he had one under test and got around 2W saturated but said 1.5 w is achievable without to mu...

Hi ben , I have both 2.4 and 3.4 ghz amps from minikits I would suggest getting in contact with mark kilmer from minikits and asking him although I would think the input and output striplines would be a problem. 73 . mark VK2AMS

My personal view is that distance based scoring would be fairer and more equitable than the current grid square arrangement . (my two bobs worth). cheers . mark VK2AMS

Hi Ron , this indeed serious news and I for one will be sending the WIA a letter, you and your small group have done a fabulous job in promoting AR , I used your school to get into the fold and to upgrade to advanced and have actively promoted your school to all incoming candidates. I am extemely co...

gday all here are some pics of the 5.7 GHz transverter using graham VK3XDK'S excellent boards, i also used his switchable dds L/O unit and have amp with 6W output . works a treat! . cheers .mark VK2AMS http://i1202.photobucket.com/albums/bb374/vk2ams/57ghztransverterfront.jpg?t=1303971143 http://i12...

Gday Lou the unit is 10 "wide x 14 " long x 4" high , I get 4x2" aluminium box section and rip it down the middle to use for the sides then use 2 mm sheet for the top and bottom , etch prime then drill and spray can black . cheers . mark

gday all I completed a 3.4 ghz transverter from minikits the other day using the 500-600 MHz oscillator and oscillator heater option and also a 2W minkits amplifier, mark has now developed these EME universal microwave boards utilizing pipecap filters which are used for the transverter /multiplier /...

gday kirk excellent contact with ross this morning, I could hear you in and out of the noise floor , I have a shocking take off to the south ! had a visitor turn up soon after so will have to try again soon. well done on the video too!! cheers . mark VK2AMS

same here! norm it will be the first time we have met in person
cheers . mark VK2AMS

Gday Rob ,thanks for the wrap, I have a 4 position rotary switch on the front panel and can monitor system voltage, forward power, reflected power and amplifier voltage, I made the horn feed for a 600 mm prime focus dish I bought at wyong last year ( it was a 24ghz set up , I still have the 24 ghz f...

me again , another pic vk2ams

gday all here is a pic of my 5.7 ghz transverter 5 w output very happy with graham vk3xdk 's fine workmanship and design including the L/O. cheers . mark VK2AMS (still trying to get used to posting pics!)

gday alan , I bought one of the israeli oscillators programmed for 2664 Mhz and connected it to the vk3xdk multiplier for my 5.7 ghz transverter but whilt there is 6 db out of the oscillator (tested) I am only getting .5 db out of the multiplier at the correct frequency 5.328 and am at a loss as to ...

gday adam this is the one I used on my 10 ghz trvtr and also will use on 5.7 ghz, they work well after 10 min warm up to stabilize. cheers . mark VK2AMS http://cgi.ebay.com.au/ws/eBayISAPI.dll ... K:MEWNX:IT

Gday rob , I have printed and laminated the circuit diagram and it is prominently displayed in the "shack" but I am having trouble sourcing the pi resistor (any leads)?. cheers . mark VK2AMS

like the circuit david , it is now archived for usage soon! thanks 73 mark VK2AMS

gday all , change of plan re the portable ops, as the xyl is crook (not well) I dont mean cranky i will be home station 24 hrs with 6m, 2m, 70 cm. 23 cm. 13 cm, and 3 cm for the the field day . good luck to all . 73 . mark VK2AMS

Gday all I will be portable at killabakh QF68EG and will have 6, 2, 70 , 23cm possibly 2.4 and 10 ghz if I can fit them in the car (used to have a van but it died . good luck . cheers mark VK2AMS

Gday Rob it is a 65cm dish it was just the photo angle there was a group of bikers up there and they got me to take there photo so returned the favour 10 ghz inside transverter.JPG heres the inards of the transverter, not pretty but it works I am using a G3WDG pll set at 2556 mhz with a pickaxe chip...
