Thanks. Presumably just adjusting for minimum SWR won't tell us this. dipole space) the impedance Thanks for the corection. I wonder why it is our gear is always designed for a 50 ohm load, then?

I wonder what the RF is doing to your hand? :-) What I am trying to do is get a set of counterpoises/whip measurements that I can use to reproducibly set the ATX for best performance on any band

Hi all, I had Sunday 13 May 13:00 a short contact from Holland to Slovenia on the 6m band, with my FT817 on a 12V gel cell, 5 watts on an open wire 6m horizontal dipole on about 9m height. S59MA got

Can't compare but the MP-1 works great. I am really pleased. Paul KB8VWV

Tom, Sounds like a neat idea. I may try this real soon. I also like the tapped coil idea, sort of like an outbacker. I also like to listen to SWBC and an antenna that I could resonate in different

Julian, I did use my old 817 very much mobile and will do when I get the replacement one. I use the 5w for VHF/UHF so find it easier to program in repeaters for where I am heading rather than try and

I find it easy to get 1:1 SWR by tuning the ATX to about 3 or 4 SWR blocks then placing my hand about 2 inches fro the aerial and moving it up and down till I get resonance. Changing the Q assume,

I can vouvh wholeheartedly for the proAm too. Excellent aerials, I worked all ovr the globe with 'em and have a nice qsl card from a JA1 to prove it (among others). You can keep yer auto atus and

You had the jumper correctly fitted I suppose? David

What do you use these name tags for? I can't say I've ever found much use for memories in a radio. I've programmed in a set of channels for the UO-14 and AO-27 satellites, and I programmed a few more

Hi David, FTBasic for me is an excellent memory manager that allows you to enter/edit/delete and enter name tags into the radio from the PC. I must admit I dont use it for control of the radio when

I have heard the lunch menu conversations, but our local repeaters seem to focus on more varied subjects. From theatre reviews to old equipment restoration. My Advice: IMHO if you don't hear an

David; As a shortwave listener, I really appreciate the 200 memory manipulations in FTBasic. There are soooo many frequencies to listen for that having multiple memory files to whip in and out as

Chris, I think you're gonna love it. I can load a wet piece of string with this thing! For ha-has I tried matching a 20m dipole for 160 ... not a problem (of course, the antenna would be about as

Hi has anyone had any experience with the LDG "Z-11" QRP mobile autotuner and the FT-817 combo? I'll be using the units for mobile and mountaintopping. I was referred to this site by another ham who

David, I'm not sure if you realized it, but the 817 can actually operate from fixed locations as well as handheld. There's a lot of people who run QRP from fixed station locations and the 817 is a

a form of computer control over one's 817. Good point,i guess if you want to look like a yuppy with a laptop and a small rig.......... No really,its the ease of getting to the memorybank to access the
