Re: New Antenna for the FT-817 and other QRP portables...
David Harvey
Guys, guys. I don't believe it is a joke. Go read the info at thewhen the whole thing was so obviously a joke at the expense ofVery well done for a joke.!!! pages. They have photos of the gadget. It's much too much trouble and work and expense to be a joke. If they really have come up with a variable transformer that does tune all that range, then it's a fan-bloody-tastic breakthrough. Are we all too clever or cynical? Are you all going to tell me I'm too gullible or stupid? Laws of physics, etc... I emailed this "lebloke@..." and this is what I got back: BEGIN QUOTE Date sent: Sat, 16 Jun 2001 00:10:17 -0400 From: lebloke@...

MOD problems
I just bought a FT-817 at HAMCOM in Dallas a week ago. Works like a charm. Since I am an Army MARS member, I tried the extended frequency mod.
I did the solder blobs on pads 1-4, and cleared the solder blob on the 5th pad. No extended TX on HF/2M/440. Have done the power + V/M + F reset many times with no effect. Also, when I do the power + V/M + F reset the display comes up 160m - L 1.800.00 Nothing else shows. Nothing works until you hit one of the other function buttons, then the display reverts back to normal. Although I haven't looked at it with a magnafying glass, I am pretty sure none of the pads are shorted to each other. My serial number starts with1E29xxxx I am baffled. Has Yaesu changed the firmware/hardware? Robert WB5PKN |
Green Wire Mod -- Do you have 3 or 5 wires?
David Harvey
I just did the Green Wire mod on my FT-817 this morning, and I found
that popping out the green wire with a pin was easier than I had expected. Before doing it, I checked the information in the FAQ, and it says there are three wires, one green, one black and one red. Interestingly enough, I have FIVE wires: one green, two black and two red. I presume the pos and neg lines are doubled (parallel) to reduce the voltage drop and current loss. My white plastic connector is a five pin. Could it be I have a newer or different version of the rig here in Australia? Or does everybody actually have five wires (but three shared connections)? 73 es 72 de vk2dmh David Harvey mailto:vk2dmh@... |
Re: Need transmitting help!
My first reaction is that you have "Split" enabled some how.I couldn't figure it out even with the manual ;-) I have been just playing around with this thing so decided to just do a HOME + POWER on and start all over. It seems to be working OK on 2 meters now. Jo K5HOY |
Re: Mini antennas for HF...
Any light weight end feed wire of lenght(without coax)or lightweight dipole (or V ) with coax/twinlead will outdo the small antennaeasily ( and prob fit in a zip-lock bag).The problem is an available supporting structure of a dipole/inverted- V OR an end fed wire (which also needs a counterpoise of some sort [and that will re-start a whole different subject all over again]) ;) isn't always available! That is the point that keeps getting missed. Or maybe the real-estate isn't available - YES a dipole will work better - but frequently it is not practical or possible to put one up! I think it was here or the HF Pack group that the "Black Widow" fishing poles came up last week. I have purchased 2 of the 20' versions (about $45 total delivered from www.cabelas.com - ordered Saturday, had them Tuesday ). I have fashioned a mounting horn out of 1 1/2" PVC pipe to hold them in a V (upright, not inverted) and plan to try my design using wire wrap wire for my trials - if it works, I will used 26 gauge flex- weave from Radio Works. What I have modeled using NEC4WIN is a triangle loop fed at the BOTTOM with a gap opposite the feed point. Each leg is about 19.5 ' up the V and then 14 ' towards the opposite side accross the top with an insulator in the middle - probably use a rubber band for lite weight and tension. With it mounted at 30" - inches not feet - picnic table-top heigth - the modeling shows some nuls off the side, but better performance than a full size 1/2 wave resonant dipole @ 20' on 10/15/20/40 and @ 40' for 80. Lower angle of radiation and more of it at the horizon! In fact, on most bands, the angle gets lower when ground mounted. It also looks like it has some pretty good high angle stuff too on the lower bands for NVIS - with the zeinth pattern sort of a 3 leaf clover shape - now if I can get the Z-11 to match it on those bands - first try will be with the tuner right near the feed point and NO balun - we'll see - think I'll go pick up a 4:1 balun just in case. Could/will use my SG231 with my Icom stuff for higher power - sure that will match it. So here is a self-supporting antenna that looks like it will perform well, cover a broad range bands, is fairly light weight (I'll weigh it later), will be easy to mount, doesn't require a counterpoise/groundplane and is easy to build and will work with an automatic tuner - so once it is up, no adjustments are necessary - this sounds too good to be true! Maybe we should call it the Miracle Whip-beater antenna!!! Will keep all posted - but plan on having it working for June 30 HF Pack schedules. See you on the air. Don W6ZO |
More Balun Questions
Brian Frobisher
I have yet another Balun question.
I recently purchased the balun that is the companion to the LDG Z-11 tuner. It did not come with very good instructions and I am looking for some ideas as to how to wire up a wire antenna to it. Any help would be greatly appreciated. Thanks |
Re: Small, portable, light weight Hexbeam
Mark,
The Hexbeam is excellent and real. In short, it was the only antenna to hold up for Chuck at Bouvet Island. It is a bit pricey, but worth it. I have the 5-band one ready to put up soon. Friends that have it simply are very pleased with the Hexbeam. 72 de Barry - W4WB --- In FT817@y..., "Mark A.

Re: Mini antennas for HF...
Cortland
I agree. For my home-made mag-mount antennas, if they don't blow off
the car, I can make them larger. So far, I am up to a Bug-Catcher made out of various masts and coils. The longer the better. Cortland --- In FT817@e..., Tom Mc <tjmc@e...> wrote: Hi Gang,work but not well! |

rf feedback
Don
here's a tip discovered recently that me be of help to others. I was playing around with an MFJ and Icom mic and the Ft-817. I noticed that when I used an rf power any (35 watts) for two meters, and the MFJ mic I would get rf feedback on the transmit audio. Really distorts the audio! The Yaesu hand mic did not produce the same results, it worked perfectly.
I discovered that you can remove the coiled cord from the Yaesu stock hand mic, (squeeze thru the boot at the bottom of the mic) and you end up with a very well shielded cat 5 cable that can be connected to the MFJ or any mic that requires an RJ-45 connector. Don Johnson |

I found a website that some of you are probably already aware of. This company manufactures a portable 2 element beam made of wire and fiberglass spreaders. I believe the weight was under 8 pounds, the gain was around 4-6db, and the turning radius less than 10 feet on 20M. They also have a 5 band beam. I haven't purchased one of these yet, but I've read more than a few good reports on them. It seems they are comparable to a trapped 3 elem./3 band yagi in performance, but with a much smaller footprint. The wire element lengths are full sized, and they're suppose to quiet like a quad. They also sell collapsible masts for portable op. If any of you have any experience with these I'd sure appreciate any comments you might have.

Slinky dipoles
I had a 160 meter slinky antenna as an inverted v. It worked very
well. A rope down the center was secured to the loops at short intervals to keep sagging to a minimum. They come in at least 3 sizes. I plan to use the smaller size to make a 6 meter portable version for the FT 817. L. Smith ka4lbd |

Web site update - THP HL-50B infomation
Caitlyn M. Martin
Hi, everyone,
I began work this morning on an amplifier section for the Tokyo Hy-Power reflector web site. It will have four pages, total, and the one that I think will be most interesting to y'all is the page with info on amps for use with low power rigs. That page is about one third done, and I have to run otherwise I'd get it done now. The main thing, especially for those on the FT-817 and HFPack groups, is that detailed specs and mod info for the HL-50B are already posted. The page, which is a work in progress and is not yet linked from the other pages, can be seen at: Comments, contributions of more info, and constructive criticism are always welcome. I hope this page can provide useful info to those considering an HL-50B to go with their FT-817 or other QRP rigs. 73, Caity KU4QD |
