perhaps the frequency counter function in the analyser isnt reading the correct frequency? you can listen to the carrier coming from the analyser on your 817 and see if its on frequency Rob.. surely it couldnt be that simple though.. what about an assembly problem, like excessive lead lengths on com...

Hi Ross and John, Ross I think you may have mixed me up with vk2jdh... quote VK2JDS wrote..quote, "I believe that your 1kw permit does not allow MS". unquote that wasnt me.. and JDH hasnt seen a high power permit by the looks of it I have a high power permit as you know, and have kept quie...

Hi Graham, in my EME hut i have a old hand-me-down ibm celeron 1.5gig laptop with an external screen plugged in the side vga socket for my moonbounce work (why? because its very rf quiet!, and has wifi to the router in the house) with the right driver installed you can split the screen across the la...

This is so true, a frequency we needed for the town repeater in Orange has been held unused for quite a while, by the remnants of the old Orange radio club, whilst the new regional club required it. Sadly the surposed 'owner' wouldnt release the frequency, so we had to adopt a frequency that our cav...

once you have worked the locals, its time to scrounge a dish and work some real dx off the moon

Fri Dec 13, 2013 4:04 pm About 40 years ago the Sydney Harbour Bridge had boom gates that opened when you paid the toll. One particular gate could be activated by your 25w 2m fm mobile. This gate was very popular with the local 2M mobile users. Ex VK2AD now ZL2KL Yep, it was the far left tollgate o...

this one did the rounds a year ago, yes its plausible, but just locking the car standing next to it (metal) will ensure any sniffers 200 metres away overlooking the carpark wont hear it. very low powered uhf doesnt propagate well around a carpark full of metal as you know yes there was a utube video...

there was a vk4 chat net on 7095 this morning....

the prf15 UHF repeater has had its final tune-up and test. The duplexer has been stripped and new silverplated cables and N connectors fitted, newish silver plated interconnecting N cables join up all the hardware. its all in rack mount cases ready to install and runs on a single diamond vertical us...

Hi , I will be activating a portable station for guides, senior guides and rangers from a campsite shed at milkers flat, north of bathurst. ops start at 1pm and will run till dark, not sure about sunday yet it will be using my callsign vk2jds 80 to 10 metres 100 watts, bushcomm offcentrefed wire, ca...

definately put in a cup of water
microwave ovens need some sort of load, if you run them empty they arc and carry on. hence water solves the problem.
but, the microwave test is good for checking plastics of all types for rf absorbtion

just dont put in anything metal...

Our local radio club , the central west radio group, put in a club submission regarding the matter, and some of us also put in individual submissions, but of the submissions the ACMA received i am sure there were several clubs representing their members. the submissions would then represent a Lot mo...

have a look at the voltage on the spec sticker on the battery pack Wayne, dont rely on whats written on the charger as that voltage will not be close to your battery pack volts. you can tell if its 3 cell or 4 cell. 3 cell will be about 10 volts, 4 cell will be 13 or 14 volts as they use 18650 cells...

test freq is 439.025 -5MHz offset, running on 2 diamond verticals at 950 metres on a mountaintop. qf46pu north-east of orange, nsw central table lands

The repeater has been running solar powered for a test run on my mountaintop. it all seems to be going ok , but i did change the link cable for the transmit keyup. using the db25 on the back of the mainframe board results in keyup on carrier detect, but wont allow you to program the tail length with...

today was very successful, I got the unit to forward the transmit audio and did a further tweak up on the cavities. to fix the audio i powered up the transmit exciter pcb externally from the mainframe and applied ptt. next was poking about looking for audio to the vco and setting the jumpers on the ...

more progress, the unit is now keying up and there is a tail which is programmable on a dipswitch, info from the manual. the next job is to port audio across. the secret is using the db25 connector on the back of the mainframe pcb, and jp6 on the mainframe for the audio. you dont need to use a repea...

more progress on the repeater for the club . Amateur Radio Central West Group. (the group covers most of the central west of NSW rather than the old orange club which had problems....) The receiver is working well , but requires the 'mute' button on the control panel to be pressed to actually hear t...

some modification info on prf15's you fellows might be interested in : i have a prf1520 here, its programmed by dip switches on the back panel, or can be set using jumpers on the receiver and tx pcb's themselves. the 1530 model is the front panel programmable one this one is the 450-470MHz version a...

I tell people that my hobby is talking to people all around the world. No mobile phone, no call charges, no internet, just raw radio and you make contacts yourself by the freedom of choosing what aerial and frequency you think is best. Whether it be off mountaintops, while driving around touring the...
