Hi Guy, Thanks for your interesting comments on our local DU dead zone.
<<< It would be interesting to know the mechanics of why the DUs are absent. Perhaps it's simply the greater distance? Difficulty of a trans-equatorial route vs. polar for the signals? >>> Well, my own opinion is that South Hill is the most likely culprit. South Hill slopes upward for both of us, and probably attenuates DU's the same way that the Cape Perpetua ocean cliff attenuates domestic stations on the back side (and it does a really good job of that, by the way!). As we both know, a sloping hill can boost up MW signals from the opposite direction when you are halfway up the hill, but it does a real number on the signals behind the hill. At our locations here in Puyallup, DU signals are "behind the hill" for both of us... and we seem to pay the price! 73, Gary DeBock (in Puyallup, WA) -----Original Message----- From: Guy Atkins <[email protected]> To: irca <[email protected]> Sent: Wed, Sep 5, 2012 1:52 pm Subject: Re: [IRCA] TP's & DU's for Wednesday, September 05, 2012 I agree with you, Gary! DU are depressingly absent from Puyallup, year after year. I'm not out chasing the DX from home nearly as often as you are, but in nine years of living here I've logged TPs and TAs, but not DUs. The closest I've come was RTM Kota Kinabalu on 1475 at a surprisingly good level... but Malaysia's not exactly Australia or New Zealand! It's closer to DU-land than the Japanese, Chinese, and Korean MW outlets that are the normal fare when overseas MW DX makes it to Puyallup. It would be interesting to know the mechanics of why the DUs are absent. Perhaps it's simply the greater distance? Difficulty of a trans-equatorial route vs. polar for the signals? 73, Guy Atkins Puyallup, WA ------------------------------------------------------------------------------------------------------------ > Date: Wed, 5 Sep 2012 12:36:32 -0400 (EDT) > From: [email protected] > To: [email protected] > Subject: Re: [IRCA] TP's & DU's for Wednesday, September 05, 2012 > Message-ID: <[email protected]> > Content-Type: text/plain; charset="us-ascii" > > This area is a notorious DU dead zone.
