Re: Icom IC-718 receive problem
I suggest you locate the relay and if possible open it , run some dry paper like butchers through the relay several times and see if it helps ?

Re: Software for calculating feed impedance
"VK3LU"Thanks Geoff, That chart makes trying out the 21ft6in 30/20 vertical I made worth a try. I don't know why I have never used it :oops: I still think the 43 ft vert is the best choice from what I have read. But I can't do a thing about it up here in VK4 :beer: Cheers Nev " It's q...

Re: Software for calculating feed impedance
you could use a 32'6"vertical but it is not as versatile however it does offer a good signal on 40 m , 15 with some tricks and perhaps another smaller vertical for 10 and 20m as well ? , or if you have some trees then a 43ft sloper perhaps

Re: Software for calculating feed impedance
Have a read about the 43ft vertical . mine performs very well and cost not much

of course grounding systems help but need not be complicated or costly

""VK4Bxi::There was a Ham in South Africa making them. Worked out at about 25 Rands a packet and very cheap for us. I still have a few packets of them. I will find out if they are still available if there is interest.

Re: Software for calculating feed impedance
If using a std design then the impedence will be easily available , simply measuring it when built will aid in matching but what objectives ?

Re: Free WIN 10 upgrade
I upgraded the win8.1 machine and the tablet , the win7 hardware is over 3 yo so not upgraded , imho win10 seems better than 8 so how good is the hardware ?
no rush either , there are other o/s you might consider for old hardware

Re: Help!!...NBN Interference
How about doing a short survey with an rx walking off site and around the site to see where it is worst , should be interesting then you can make an informed complaint ?.
