Bury Flex is another foamed PE dielectric cable with a 9.5 AWG stranded bare copper center conductor. As such, you can safely presume that its losses on HF and higher frequencies are just slightly more than LMR-400 (non UF) coax.
Bury Flex is not a flooded cable and it uses a standard PE jacket. - Glenn W9IQ |

Quote Pick a mileage that is beyond or mostly beyond politics and we'd be OK. That was the intent, to keep it in the amateur radio realm as much as possible. Grid squares are used in the hobby already, so why not? My apologies for the suggestion. Consider it withdrawn. ![]() Quote I wouldn't mind a rule that allowed us to activate P5 at 10, 15, 30 miles out (whatever won't get the boat captured Mayaguez style). I'm not sure it is a good idea to bypass government authorization for activation within or outside a country's sovereign territory or area under its jurisdiction, like the EEZ. I think it's a change too far. We are now entering relativism, not good. I'll preemptively apologize for this one as well. Consider it withdrawn. ![]() |

Speaking of buryflex, I understand this is a flooded coax. Is there any sort of special cleaning preparation involved to clean off the flooding goo when mounting connectors? Solder PL259’s vs. crimp?
I’ve always wondered but never got around to asking Davis, as I’ve never used it. |

Quote I doubt that there is many in NA that needed V26 for any slots that are any way active on the bands, Prepare to be surprised. DX is a renewable resource. There are new DXers coming on stream, always. There are also DXers who, having worked in eras where DXCC Challenge wasn't "the thing", have a lot of experience yet a lot of unfilled band slots out there and only now decided to fill them. Anyone with DXCC Challenge 1000 to 1500, even in North America, probably had quite a few slots they were looking to fill. Not to mention the increasing numbers of younger DXers who have decided to avoid cards. A V2 operation that promises LOTW (V26EI did) is going to get calls from those in NA that have the slots worked but refuse to spend the bucks on cards. Some out of cheapness, some because, well, cards are a comparative hassle; LOTW is much easier to actually turn in. In any case, that was a fine operation by any standard, mode percentages be damned. |

Thanks for the info! I ordered some new coax to replace this damaged stuff. I will test it as you suggested, and if it's not beyond repair, I'll use it for the antenna I'm putting in my attic.
Thanks again, it's much appreciated! N8RFY |

Quote What is so special about 3X4? 10 miles seems close enough. It's a pretty arbitrary choice in the end. The grid squares vary quite a bit in size as one heads closer to or farther from the equator. Pick a mileage that is beyond or mostly beyond politics and we'd be OK. Some nation states claim a 200 mile "border" from their land mass over "their" oceans. But a lot still pick more reasonable distances. So, yeah, 10, 16, 32 from the nearest land, some distance like that could be picked to minimize political interreference with DXCC. I mean, we already have plenty of external politics interfering (EZ, P5 right now, at least), so if we are to bother with this, we may as well have a rule that recognizes that reality. I wouldn't mind a rule that allowed us to activate P5 at 10, 15, 30 miles out (whatever won't get the boat captured Mayaguez style). Screw P5 and its paranoid little government. We don't have to put ourselves in thrall to them. We do so now out of choice. |

I will check the voltage at the battery under full load. I checked the current draw under full load and it was 50 amps for the radio and amplifier. The factory alternator is rated at 140 amps since this car has the heated seats and heated rear window. Of course that is a cold rating. I know how to check the voltage drop on the wire, fuse holder etc. My analog wattmeter pegs the 300 watt scale on peaks on most higher bands. RM Italy says the amplifier has 4 transistors in the output. I guess I should be happy and not try to get more since the antenna is rated for 250 watts.

I'll add one little thing to what WB6BYU said. When you have completed the wrap of tape over your well sealed repair spot, take a small black nylon tie wrap and tie down the end of the electrical tape. This does help, I think, to keep it from coming loose over the years.
