Re: [digitalradio] OFF TOPIC
Ri ck, I`ve built both. I`ve compared them side by side and the slimjim wins. I could hear and get into repeaters with the slimjim that I could not with the jpole. Plus it matches much easier and is easier to build than the jpole. I always used the 450 ladderline to build the slim jim. The tv twinlead is a lot harder to work with. The one advantage of the jpole I found was that when you made it out of copper it was easier to mount. To mount the slimjim from the bottom. I put the ladderline in 1 in pvc and really taped a fiberglass rod to the side of it. Then I mounted the ant by clamping the fiberglass rod to a metal mast and it works good. Note, enclosing the ladderline will change the optimum feed point...hope this answers your question...73, Alan Why do you prefer the SlimJim over the J-Pole? LB Cebik did an in depth comparison of the two antennas and found the J-Pole to be slightly better in performance. Recently, our club had a J-Pole antenna building party and it was difficult to get them tuned up where we wanted them using TV twinlead. My best success with homebrew verticals has been when I used 450 ohm slotted line, but I have never tried building the SlimJim's. Maybe they are easier to match? 73, Rick, KV9U Alan Wilson wrote: You can build 2m slimjim out of 450 ladderline for less than 5 bucks...Look on http://www.hamuniverse.com, http://www.hamuniverse.com, I've built several and they are very easy to construct, easier and better than the jpole...73, Alan
Re: [digitalradio] OFF TOPIC
I haven't been following this thread until now, but are you building these antennas for portability or are you using them in a base configuration? I've found 300-ohm twinlead to be the best as far as portability and ease of construction. I live in the Portland Oregon area and haven't seen any 450-ohm ladder line, anywhere, at least not for sale. I've never worked with it so I really can't make many comments on it, but it would seem to be harder to work with and the physical size wouldn't make it condusive to back packing! Personally, I have a copper J-Pole that I can break down and take with me every where I go. I also have the twinlead J-Poles that have served me well in most mobile situations! Just my thoughts!

[digitalradio] Winter field day advice
I am in charge of the digital system for our club's winter field day later this month. I have a fair amount of experience with BPSK-31 and Olivia on 40 meters. Of course, that works nicely in late afternoon and early evening, but I need to know what/where/what frequency to use during the DAY, as we want something to show the public. I have an FT-817ND, and a variety of antennas available to me. What is the collective wisdom of this group? Thanks! /paul W3FIS in Slower Lower Delaware

Re: [digitalradio] Re: FT-450 on digimodes
Juergen, Thanks for doing the test. Now I am confused because I contacted Yaesu and sent them this graph of my measured transmit passband: http://www.projectsandparts.com/misc/ft-450tx.gif And this is what the engineer told me: Your graph shows the typical audio roll off expected. The bass band deviation for the FT-450 is 300-2500. You would expect the dBWs to peak as the filter narrows and conversely to drop off sharply as you approach the band edges. That is exactly what your data shows. Your FT-450 is performing within design parameters. I agree with your comments regarding the sound card interface roll off and I will measure this later today with an oscilloscope. But from experience this sound card (audigy 2) and i/f has been in use with my old FT-897D and I did not observe such a problem. I am quite prepared to believe it is something I am doing wrong but I will need to take more measurements to find out where the error is (if there is one). 73 Sholto.

Re: [digitalradio] OFF TOPIC
J-Poles, or for that matter, SlimJims, could be built for either portable or fixed operation from 450 ohm slotted twin lead. I have a fixed home J-Pole constructed from 450 ohm window line and sealed in PVC. Because the velocity factor is significantly slowed down by the PVC, you have adjust the size of the antenna. The 450 ohm line is available from ham dealers such as AES, etc. There are two kinds of 450 ohm twin lead that I have used. The very heavy duty type with multistrand 14 AWG and the much lighter single strand 18 AWG. While I don't recommend the 18 AWG for long term use, e.g., making an open wire fed antenna, or G5RV and ZS6BKW types, this can work well for lighter weight portable dipoles, and making J-Poles for VHF, either free hanging or inside a PVC. For back packing I would choose the TV twinlead and have it as a roll up and if I used a walking stick, would have a ready short mast. Of course you only need the twin lead for the Q section and the main half wave part of the antenna can be wire. I have done it both ways. When using the 450 ohm line inside PVC it tends to stay firmly upright and does not sag like wire is prone to do. The reason I don't like the copper tubing designs is the exposure of the connections to the weather. With a soldered connection on the J-Pole encased in PVC, it seems to work well. I use a different approach with the addition of a bottom Tee which is positioned so the feedpoint is at right angles to the Q section. I hope to have a write up about this in the files section of the hfdec yahoogroup to add to our antenna projects section. It can never be published in QST since it is not finessed and uses things like electrical tape to throw it together, HI. 73, Rick, KV9U Rodney wrote: I haven't been following this thread until now, but are you building these antennas for portability or are you using them in a base configuration?

[digitalradio] Re: FT-450 on digimodes
It's hard to believe that the engineer has looked at the scale ... If such a characteristic would be standard I would not recommend the YAESU FT-450 to be used for medium or wider digital modes like Olivia etc. I remember that first tests of the FT-450 complained about poor tx audio performance, but I don't remember the modification on later versions. As it looks my radio (bought in August 2007 in Europe) performs better in combination with the soundcard I have. 73 Juergen, DL8LE --- In digitalradio@yahoogroups.com, Sholto Fisher sho...@... wrote: Juergen, Thanks for doing the test.

Re: [digitalradio] Re: FT-450 on digimodes
Hello Sholto, In the Yaesu FT-450 Yahoo group photo files there are a series of receive BW scans I took with my 450, with a couple of 857 scans thrown in for comparison. If it has a narrow CW filter, the 857 IMO wins on filtering and its audio DPS works extremely well as an adjunct to accessory filters. The 450's SSB response seems by comparison rather peaky, just as the plot linked here indicates for transmit. Unfortunately, the 450 lacks the ability to move the carrier closer to the filter skirt. I have not done 450 output power measurements vs audio frequency, but it sounds like a worthwhile experiment. I will say that where we use wider modes for MARS, such as 1K MT63 and Olivia 1K 32 tone (very nice weak signal performance) I have not noticed the 450 being less effective than a Harris RF350 (300 Hz - 3000 Hz BW). But I have not looked, either!

Re: [digitalradio] Re: FT-450 on digimodes
Cortland, Thanks for the info. Can I ask what firmware version is on your 450? Presumably the tx filter is implemented by DSP on these models and it may just be a software issue which in time may be fixed. The version here is 0194. Regarding the rx filtering I am quite happy with the rig. Using a software spectrum analyzer (MultiPSK) the rx passband looks fine. I had an FT-897D with both a 300Hz and 500Hz filter and while the 450 DSP CW filter is not quite as effective I still find it surprisingly good on CW and general receive. In fact at this point I feel it has a better receiver than the 897. Certainly the contour is a big help on some signals and the NR seems not quite as weird sounding as the 897 was. The manual notch is also very impressive and much more useful than the 897 auto notch. CAT control on the 450 is much better too, it is more responsive than the 897 and works very well with HRD and OmniRig. All in all I am quite happy with it and if one day a software update comes along and fixes the lumpy tx passband it will be a bonus. 73 Sholto KE7HPV Cortland Richmond wrote: Hello Sholto, In the Yaesu FT-450 Yahoo group photo files there are a series of receive BW scans I took with my 450, with a couple of 857 scans thrown in for comparison.
