TP 27 Jan Victoria version. |

Monday, January 28 2019
This morning might take the title for the season's worst...
pretty darn good audio (all of it understandable by a native speaker, at least briefly):
not by any means Reasonable audio at times during the period (much of it understandable by a native speaker, though often battling with splash or noise):
the above passing through
not so reasonable audio, occasional words or phrases in splash or noise could be understood by a native speaker:
not in the slightest Burbles in the splatter and noise (if lucky, language might be guessed at by cadence of talk, or parallel established by changes in talk or music)
594 JOAK NHK interlude music recognizable in the gloom 1510UT Strongish het, no or "near imaginary" audio (either undermodulated or ravaged by splatter) 567 1566 seemed to be Asian; 891 1017 seemed to be DU best wishes,
Nick Nick Hall-Patch Victoria, BC Canada

Coax Cable |
|
Monday, January 28 2019
Haven't seen any response to this, James, and am probably not going to be much help.
I've just used RG58 variants for up to 100' in permanent installations around the yard, 10 to15 years in some cases. One of them runs through about 70' of rigid PVC electrical conduit IPEX #032907 and is buried. Mind you, I've heard that although such conduit will keep the groundwater away from the coax, water vapor will condense inside, leading to a wet interior anyway. That coax still seems to work,so maybe it's dry...or maybe not.
On DXpeditions, I've run over 500' of RG58 coax to DKaz'es and such, and not suffered particularly.

I have read that RG-8U is good for long runs of a 100 to 150 feet, and if I was to bury my coax, which is the best pipe/conduit to use to bring my cables into the shack? thanks James Niven Austin, Texas

Coax Cable |

Monday, January 28 2019
High, Jim! I think you have little to worry about no matter what you choose, electrically, at least. The more important issue is durability. Depending on what I'm doing, I use different coax cables. Lengths shouldn't be an issue, either. We experimented with lengths up to 1000' at Grayland many years ago, and no difference was seen between (K9AYs, I believe) at the ocean shore, or right next to the Grayland Motel, so don't worry about that. Next is weight. When travelling, I'll use the super thin RG174 coax (50 ohm), which fits nicely into the suitcase at minimal weight. For cost, one can't beat 75 ohm RG6 coax which can be purchased everywhere for pennies a foot. I've used that a lot over the years, and it lasts well for a number of years outside. Now for more permanent weather impervious coax, I've used a very heavy duty Belden 8215 milspec 50 ohm cable. I was fortunate to buy military surplus brand new role of about 1000' or so years ago, and it's virtually indestructible, and can be buried without worry about water infiltration, at least not for years. A local DXer, Brian Chapel, gave a great idea, though, about what to use with regular coax if one buries it on runs. He recommended buying a long run (or runs that have been thrown out) of garden hose. What a great idea. Then you simply run the coax through it from one end to the other. Don't know if anyone has tried this, but if it remains intact, it should keep coax dry and clean for many years, buried. Any other thoughts? 73, Walt
