MP-1 vs ATX
Julian, G4ILO
Following my success at getting the ATX working the way I wanted, I thought
that I would try and tackle once and for all the problems with the MP-1. I have never managed to get a very good SWR with this antenna, especially on the lower frequency bands. Normally, I would just solve the problem by using the K2's ATU. In the course of my experiments I found that my note yesterday that the ATX can be resonated on 30m and 80m using a ground system of four 10ft radials is probably incorrect. Because the battery of the FT-817 had long since expired at the time I did that test, I was powering the radio off the power supply. It would appear that a much better ground was provided by the power supply than by the MP-1's 4 radials. Disconnecting the power supply and I could not get a good match. I think that if you want to use the ATX on 30m or 80m you will need to make up two more tuned counterpoises for those bands. Although I am quite pleased with the performance of the ATX with counterpoises, if you want an all-band portable capability you will have to carry around a lot of wire which will weigh more and occupy more space than the antenna itself. It's a pity that I couldn't make the single non-resonant ground plane idea work, but such is life. Back to the MP-1, and at this point I switched to the K2, which still had power in its battery, so I could get isolation from the mains ground. Disconnecting the radio from the power supply meant I could no longer get a good match. Moreover, the SWR constantly fluctuated, suggesting that there was RF on the feeder. Using a coaxial choke solved that, but made the best achievable match even worse, since for grounding the antenna was now totally reliant on the 4 short radials. My conclusion is that the system of 4 10ft radials used by the MP-1 provides a totally inadequate ground for satisfactory operation, especially on the lower frequency bands. The proof of that is that in A/B tests between the ATX and a counterpoise cut as I determined yesterday, and the MP-1 on its standard ground system, the ATX was demonstrably better, by perhaps getting on for an S-point. (These comparisons were done on 40m and 20m only, due to the lack of any signals on the higher bands.) A quick test using one of the counterpoises I made yesterday with the MP-1 would suggest that it is possible to get a 1:1 SWR with the MP-1 using a tuned counterpoise for each band. However, it still appears to perform no better than the ATX. The MP-1 may outperform the ATX on the WARC bands due to the fact that the ATX uses a greatly reduced whip length on those frequencies. However I will leave that comparison for someone else to do as I have spent enough time playing with antennas for the moment. As one final test, I did an A/B comparison between the ATX and a Pro-Am 20m whip. The Pro-Am was mounted on the MP-1's tripod using the 4 10ft radials plus grounding through the power supply. The Pro-Am was at least an S-point better than the ATX. Some final speculation. Although the MP-1 ought theoretically to outperform the ATX by virtue of its bigger loading coil, you will only get the benefit of that if you have a very good ground system to go with it. In our portable application with short wire ground planes or conterpoises, it is the ground resistance or the counterpoise, not the coil resistance that is determining performance. Therefore the ATX will probably work as well as any antenna of similar size used in that situation. Anyone want to buy a used MP-1? :-) -- Julian, G4ILO. (RSGB, ARRL) Home page: |

At least the directions were polite!off-topic. I once had ( and lost, sadly ) a priceless Japlish brochure on the Heath/Standard HW24HT dual-band radio... "Standing on the summit in happy handy!"

RATS FT-817 Control Software
Mark A. Smith
Hi,
Just wanted to let the group know that I have uploaded a new version of the RATS FT-817 software to our website. Version 1.1.5 is now available. This newest version fixes the most glaring problems associated with the pre-release version. The S-meter has been calibrated to the radio. Scanning is faster, and pauses when the squelch is open. Synchronizing RATS with the radios frequency and mode is now included. The AB and SPLIT functions have been fixed, and the Help file has been updated. I still have a few other bugs to work out, but I believe that I have made significant progress with this latest release. Please download a copy from my website and provide me with your feedback. Thanks in advance for your help. 73 The website is at Mark A. Smith KB5KYX |

Re: New Product
On the Daimond page you will see a multiband dipole, has fiberglass
spreaders and a balun in picture. Thia is the antenna sold by Yaesu. I have one at QTH and it is a great performer. Low SWR across all HF bands. Not great on 160, fais on 80 and FB on all others. Wonder if we can buy direct from Diamond? Anyone have an e-mail address?? Tim O'Rourke KG4CHX |

of old manuals from the Japanese that had been translated into English. These included these memorable translations: - Please to make wet with water. (somewhat understandable, but funny.) - Please place under transportation. (no, it does not mean to chuck it under you car, this was for an insert for floppy disk drive in case it was being moved to keep the heads from banging around inside the assembly). At least the directions were polite! Does anyone have more these types of chuckles, I know this a bit off-topic. laz -- k2laz On Mon, 14 May 2001 julian@... wrote:

FTBasic update
FTBasic V1.4.502 is now available at
I have addressed the issue that Pres raised a few days ago regarding the 12.5 kHz spacing and the Frequencies.txt file. If you put a decimal point in the frequency it is treated as being in MHz (up to 5 decimal places), otherwise it is treated as being in kHz (no decimal places). Bob G4HFQ |

When I use it as a Scanner, my DELAY function doesn't work.
David Harvey
When not Hamming, I listen to the local UHF public service band
while I'm at my computer console. I have programmed in the frequencies I want to listen to in SCAN mode, and have also set the FT-817 not to check some of the other frequencies, such as HF ones. It makes a pretty good scanner, except I cannot get the little beast to pause for 3, 5, 10 seconds when the audio stops and squelch closes before resuming the scan of other channels. Have I missed something here? I have tried the 0, 3, 5 and 10 second options. None of them work. What is the secret, folks? Cheers. 73 de DAVID VK2DMH in Sydney, Australia. |

something you could easily make yourself. I wish some company would do something really innovative and come up with a small, low power consumption DSP PSK31 *modem* which you could drive from a palmtop via a serial port. Then portable PSK31 operation would become a reality. (I really have no desire to hump a PC laptop around in my backpack along with the radio gear.)
