Chalkline antenna reel -- advice?
Glyph
Some people have posted messages about rolling antenna wire into an empty chalkline reel -- it would make a fine container, and it would make retrieving the wire fast.
Today I tried rolling some #22 insulated copper stranded wire (90 feet purchased at my friendly Rad Shak) -- and probably only 60 + feet went in. Anyone had any luck getting as much as 100 feet in? Where can one buy #26 or so insulated wire? Rad Shak doesn't seem to carry anything smaller than #22. I checked out my local ham flea market last weekend with no luck. Has anyone tried winding enameled one-strand magnet wire into a chalkline reel? Due to lack of plastic insulation, it should be possible to get 100 feet of wire in OK. Trouble with magnet wire is that it can get kinks in it easily, it can be unwieldy and it can stretch. I definitely want to stay with copper wire for this application. BTW, I took my 817 and my Emtech ZM2 tuner and attached adhesive velcro strips to the top of the 817 back behind the speaker, and to the side of the ZM2, so now the tuner can be held to the top of the 817 with velcro. A short section of coax runs between the front of the rig and the tuner. Now the controls of the ZM2 are as easily accessible to the operator as are the controls of the 817. Bands didn't seem to be doing much this weekend. Quite a bit of QRN here. -- Bil KD6JUI |

The 817 mike uses an RJ-45 connector. Heil sells an excellent adapter that converts any Yaesu "round" connector mike cable to the RJ-45 needed by the 817. 72, Bill W4RK Nashville, TN USA ----- Original Message -----

Re: Digest Number 454

Hello to the group,It looks like the filter can be stacked,I have the 500hz
CW filter not installed it yet ,but it looks like the Side Band filter could stack on it .Wonder what would happen it put in the 817 stacked and select from menu on what to use by the radio,have I been around too much RF or what? Just thinking,73 to all.....Len N9HKG |

MALDOL whip - Loading Coils
Hello, this may be of help. When I purchased several types of whips in the
early days, the Tokyo Hy-Power 40 and 6 meter coil. Also the 40 and 17 meter mono band AT whips, they were a little high at resonance frequency. Adding a few turns of wire solved the problem and I am now able to get a good swr across the band. It is a bit tricky to take the coils apart but on the AT type whips, I just cut away the heat shrink. A good friend of mines (KC3VO) showed my a way of taking apart the Tokyo Hypower coils by carefully heating the coils to remove the outer cover. The reason I mention this is because the Maldol coils appear t be made the same as the Tokyo Hy-Power coils. I hope this helps and good luck. 73's Lee/k3re |

Re: Battery compartment (Dave Perry)
Dave:
That is exactly what I needed. Did not know there was some sort of removable tray for the AA batteries. On another note, I assume that when unit is powered from a ext 12v source that there is some sort of control over the charging of the internal battery. Do you know if the charge level of the internal batt is adjustable via software? Thinking of installing a 12v internal batt supply if the charge level can be adjusted up from 9.6 v Thanks Frank W9LVC --- In FT817@y..., "David Perry" <david.perry3@v...> wrote: Buy NiMHs, make up pack, cut green wire, insert pack intocompartment, keep drycell tray for resale day, charge.become public domain upon submission and may appear anywhere on the Internet orin print without notice or compensation. |

ATX won't tune
Bob Conder
-Been trying to use the ATX,(connected to the rear coax with Radio Shack
adaptors) connector of the 817 on the beach in SC. Yesterday, worked Brazil on 10m, but still get several SWR bars (4 or5) regardless of the pin position, antenna height, and length of couterpoise (cut to their specs). That is, with the usual specs per Waters and Stanton instructions, get HSWR readings, so I've been experimenting. -Has anyone else had this problem? Does this mean the ATX is bad (the base of the whip will spin around on the BNC connector)? -Thanks in advance, Bob K4RLC (portable in South Carolina) |

Re: SSB Filter Test - A Winner
Barry, if you have a computer with a soundcard, could you please run
receive audio passband plots of the 817's two ssb filters? It's really quite easy to do. Please see for an example. Tune the radio to an empty frequency (e.g., 10M) and run the audio out into the soundcard audio in. Download SR5 from www.ar5.com and run it. You'll quickly see the difference in the response of the two filters. Takes a coupla minutes, that's all. 73, Barry N1EU www.albany.net/~bg --- In FT817@y..., w4wb@a... wrote: This afternoon, W3PM and I performed a few tests on the Yaesufilter sounded better, sounded crisper (cleaner), and had more punch thanfilter when compared to the ceramic filter.the audio is just fine.when using the mechanical SSB filter.

Re: mikes
Hi Stephen,
Next time try to get the counterpoise up off of the ground/grass a couple of feet and I believe you will be surprised at the improvement. [You might have to stand up to keep the counterpoise below the base of the antena. ;-) ] The ATX will never get close to performing as well as a proper (or even modest) dipole, but you can still have loads of fun. 72 de Barry - W4WB today, sitting out in the garden. The dipole is about 20 feet high.Sitting on the grass with the 817 between my knees, and the appropriatecounterpoise lying on the grass, the ATX was never more than 2 s points down onthe dipole. Admittedly this was the middle of the day, and there wasonly European stuff on 20m, but I was pleasantly surprised. |

So Frustrating.
I read about others having success and fun with the FT-817.
The only thing that has changed about my setup is that I now use the FT-817 instead of my htx-10 and FT-620b. Obviously the power levels have not been reduce all that much. Everything else is the same - antennas, location, operating methods (can't speak for propagation). I've had this nice radio for two months now and not a *single* contact. I don't expect to be heard during a pileup (I never was before), but I've called stations that were booming in before a pileup or after. I've called others calling CQ. I've tried joining leisurly conversations. Nada. I'm getting very ready to trade someone for an FT-100, but I love portability of this thing. I've checked power levels, everything I can think of is good. So, what might I not be thinking of...? |

Re: mikes
Stephen Prior
Is that 2 s points on Rx or Tx? I think the ATX works well on Rx, justnot so hot on Tx. You'd have to make me swill a lot of beer to convince theATX was in the same game as a dipole!Admittedly, this was on rx. However, since the antenna is passive, it would be going against the reciprocity theorem would it not if the same were not to be true on tx too? Also, I did not say it had the same gain, I did say that there were no more than 2 S points difference, and in dB terms that is quite significant. That said, unless I were in a totally tree-less landscape with no other supports, I'd take a wire antenna with me anytime rather than use a shortened vertical! 73 Stephen G4SJP |

SSB Filter Test - A Winner
This afternoon, W3PM and I performed a few tests on the Yaesu
optional SSB filter. We are located about 5 miles LOS and operated on 10 M with signals at S-8 to S-9. Qualitative observations by Gene W3PM were that the mechanical filter sounded better, sounded crisper (cleaner), and had more punch than the ceramic filter. Quantitative measurements were made using a true RMS volt meter by HP. The average signal was 2 dB stronger with the mechanical filter when compared to the ceramic filter. Like many others have reported, I also have had lots of unsolicited reports that the rig has good audio. Such comment is far less frequent with my FT-1000MP and Heil Goldline microphone although the audio is just fine. I should point out that the receive audio is noticeably changed when using the mechanical SSB filter. Given that you are using a good external speaker, the noise with the mechanical filter has the sound of white noise while the ceramic filter sounds like pink noise. I plan to measure the noise spectrum soon with a spectrum analyzer to quantify this observation. At this point, I am leaning strongly towards the position that the mechanical SSB filter (Yaesu or INRAD, take your pick) is worth the money if you want to optimize your SSB experience. I also have the HC-4 and HC-5 elements from Heil. When I mount them in a spare microphone and make some tests, I will share the observations. Although the stock mic seems to do a great job, some others have reported improvement with these Heil elements. 72 de Barry - W4WB |
