Re: Pictures ...

Hi All !
I really enjoyed the WPX CW contest too, didn't have a huge amount of time for operating, but the FT817 was a real bundle of fun to use on CW contesting !

Hi Julian !
I've had similar comments about the antenna I built at home for 160m. I have a very small garden, hence now large wire antennas, so I constructed a 15m tall top loaded vertical for 160m. I had all the local G3/G4's tell me I'm wasting my time, "You'll never work anything with that" came the comments, however winter just gone I was working South American, USA, and Far east stations that they couldn't even hear ! It just goes to show, it's worth trying anything, cos you never know, you may get it right ! The outbacker is an excellent antenna for the size, and so convienient to travel with as it collapses into small manageable pieces. They are quite expensive though, I think Nevada are selling them for 229.00 at the moment, Steve got his at a special price when they had an offer on, 169.00 ... lucky sod ! We should arrange a sked for a chat on the 817's sometime ... Cheers! MikeT ... g4ilo@... wrote: On the Elecraft list recently a couple of postings didn't rate the-- MikeT |

Hi Nick!
I have to say I am most impressed by the Outbacker Outreach, with 5w I could work all the stations I could hear ... I also take a full size G5RV and ATU with me, but not all camp grounds lend themselves to stringing out a large wire antenna, this is where the outbacker comes into it's own, small footprint and works a treat !

Re: Pictures ...
Mike Tatum
Hi all !
The first time I saw the outbacker's performance was when Steve bought it over to my place with his IC706MKIIG. We setup the antenna on the tripod on the gravel in the back garden, run about 15m of coax back to the shack and connected the 706, within minutes we were working USA on 20m ... I think the problem is that many people buy them and then do nothing about a ground system for them, like all short antennas, you got to do a fair bit of work on the ground / counterpoises to get any results. The Tripod from AlphaDelta makes it a lot easier to get good results quickly but even it can be improved on ! Cheers! MikeT ...

Re: 6 Meters
Hi
However, you are using a decent antenna. I tried 6 today but theWell I made a dipole out of 3 metres of thin wire, centre fed it with a bit of 50 ohm coax (12 feet!) I had lying about, hung it at an angle from an upstairs window into the back garden - the bottom was only 6 feet high - and I worked all over Europe on CW & SSB - I had a ball both on Friday & Saturday! I think the trouble with 6 is that as soon asI agree about the whip - but like I said above - an antenna doesn't need to be exotic! Try it! 72/3 Graham G3MFJ |
headsets for FT817
Has anyone tried a telephone headset for the rig? They are small and
light. And in the same vein, does anyone know where right-angle boots for 8-pin modular connectors can be obtained? I'd like to make an adapater that lays alongside the radio. I've used my old Heil BM-5 with the unit on VHF FM, and am told it sounds fine. But even that's a bit large. 73, doug |
Re: Purpose of the green wire ???
It is a low voltage sense wire that inhibits the
charging circuit from working if the AA battery tray is pluged in with any cells in it. 73, Skip NC9O __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo! Mail - only $35 a year! |

I think the earlier one required using tools to move the frequency band taps, and for dis-assembly didn't it? *** Well sort of. You had to change coils in an inconvenient way in the OLD version. Did they change to 3/8-24 standard threads on the new one? That would enable us to plug it into a regular mobile or MP-1 Superantenna FT- 817 mount. *** No. The bolt in the coil bottom is a standard 1/4-20. It is a trivial matter to make a transition part. Is the new one an "air dux" coil? *** Yes. The coil housing is PVC having an overall length of 7" as I recall. The coil is 4" in length and 2" in diameter. Textbook design. How small does it pack up? *** The bracket for window sill or table edge or ... is about 15" long. The stainless steel whip is about 23" long when collapsed (BTW, its diameter is about twice that of the MP-1 whip). It is a bit more of a pain to pack, but is easily finds a home in my carry-on suitcase fir airplane travel. No question that the MP-1 is the champ of champs for packing small. FWIW, I have frequently mounted the AP-10A on the edge of a table, a 2x4 in the clamp with a few bricks sitting on the exposed parts of the 2x4, in hotel windows, etc. 72 de Barry - W4WB

For a 33' mast try the MFJ-1910.

It should be applicable to balloons as well. The relevant point: use MUCH lower strength line from your antenna connection point to the kite than you use from the antenna down to the ground. If you lose control of the kite, the line will break at the connection point, and the antenna will fall straight down. Of course, you would ANCHOR the line at the ground in order for this to work, so it would be impossible to drag your rig off, anyway. <snip completely unneccessary comment, and signature line> Folks have used kites & baloons for all sorts of stuff for centuries (remember the Montgofier brothers? 1873 first manned balloon flight) It obviously *can* be done safely. But also, folks die every year from doing it *not* so safely, so use yer noggin! I have no connection w/NJQRP yadda yadda.... |

Hi Jerry, For travel operation the whip and 8 inch mast can all store within the body of the MP-1 if you remove the slider from the coil body and insert the 8 inch mas first. I also have a 3/8 inch nut on my 8 inch mast and that end goes in first with the nut at the far end. Next insert all the aluminum mast pieces one by one with the bottom piece having the 3/8 stud on it last and that end up. You can only insert the number of whip sections that add up to about 54 inches. I forget how many that is off hand. If you have extra's (most do) they will not fit. Sincerely, /s/ Steve, N2CKH |
