Re: [IRCA] S. AZ TPs, Monday 8/22
No doubt a lot of the noise was directly radiating into your wire. In that case, a choke is just a paperweight.

Re: [IRCA] S. AZ TPs, Monday 8/22
Then for sure you need to be lots further away from // powerlines. Here in IL/WI there are many deer. I've made a deal with them. They don't chew my wires and cables and I don't chew on venison meat. 73 and good luck..KAZ On Mon, Aug 22, 2016 at 2:53 PM, Steve Ratzlaff wrote: > Hi KAZ, > > The longwire was elevated 10' the whole distance.

Hi KAZ, The longwire was elevated 10' the whole distance. Critters chew up anything on the ground that catches their fancy, here in the desert (assumed to be packrats), so I can't leave any wire or cable lying on the ground if I want it to last more than a day or two.:) 73, Steve On 8/22/2016 12:41 PM, Neil Kazaross wrote: Steve, Was that wire directly on the desert ground or was it elevated?

Re: [IRCA] S. AZ TPs, Monday 8/22
Steve, Was that wire directly on the desert ground or was it elevated? Either way, I'd want to be more that 30-40 ft away from powerlines. Perhaps you'd pick up less noise if on the ground directly? 73 KAZ On Mon, Aug 22, 2016 at 2:37 PM, Steve Ratzlaff wrote: > I listen most mornings with the new 140' W DKAZ but conditions have been > poor lately; I don't report hets or faint traces of audio. > > This morning was a little better. > > I strung a 1100' E/W longwire last week but found it picked up high levels > of AC noise from a parallel powerline some short distance away (30-40')and > was completely useless for weak signals--I took it down today.

[IRCA] S. AZ TPs, Monday 8/22
I listen most mornings with the new 140' W DKAZ but conditions have been poor lately; I don't report hets or faint traces of audio. This morning was a little better. I strung a 1100' E/W longwire last week but found it picked up high levels of AC noise from a parallel powerline some short distance away (30-40')and was completely useless for weak signals--I took it down today. It was worth a try as I had no idea how much, if any, a parallel powerline might couple to the longwire. Now I know! I'll eventually try another location that's much farther away from the powerline and hope for better results.
