New Version of the RATS FT-817 GUI Available - It Has A New Look
Mark A. Smith
Group,
This new version fixes a problem with old mode values that were stored in the initialization files which may have caused some users to get a run-time error upon starting RATS. A problem with tuning the SUB VFO using the channel dial has also been fixed. The ability to save SPLIT frequencies to memory for LEO satellite work has now been implemented. And the big news is that RATS FT-817 has a new face plate that gives it a 3 dimensional appearance. Check it out and let me know what you think. As always please let me know if you have any problems, so that I may address them in the next update. Thanks for your help and support. 73 Mark A. Smith KB5KYX |

LDG DWM-4 Watt Meter
This may be of interest to those of you who own or are planning to buy
a DWM-4 watt meter to use with your FT817. I contacted LDG about the insertion lose of the sensors & got the following responce. It's something less than 1 db. I don't have anything that will measure less than that. Dwayne Kincaid Pleas don't flame me, this is related to the FT817. 73, Fil W8FIL |
Re: WX at 162 MHz
If I remember QST had a simple converter and I think
FAR Circuits sells the boards. It was a cover story in 1998 or 1999 I think and there was one for 6 and 2 meters. It unsed the NE602. The 2 meter unit can be tuned to work at 162mHz without changing anything except where you tune to receive it on the 817. 73, Skip Davis, NC9O __________________________________________________ Do You Yahoo!?

72-ohm twinlead
Curtis, Tony
Does anyone remember 72-ohm twinlead? I used to love the stuff for
antennas, but haven't owned any for years. I asked for it all over Dayton, inside and outside, and the general answer was there is no market for it at this time so nobody stocks it these days. Lots of folks seemed to remember it. It's thin, light, very flexible, easy to use. Does anybody know where I might buy some? --Tony K3RXK k3rxk@... |

Re: MP-1 Mobile/Portable/Pedestrian SuperAntenna for FT-817
Trevor Lewis
I hope that neither this topic nor any of those discussing it exit this
group as a result of any "heat" that anyone feels accompanied the "light" in the discussion-- I have learned and continue to learn a LOT about antenna issues & options-- and new ways to look at and understand those issues and options-- both as to my 817 and more generally. While I've read numerous books & articles (Moxon, Cebik, Severns....), manufacturers' ads, etc. espousing one or the other of the perspectives you all are testing, exchanging and debating, I find this dialogue about what works, in what conditions, with what technique... far more conducive to developing a better practical understanding that I can put to use. In fact, as someone new to both QRP and HF portable, finding out what options I can try for antennas for my 817-- and the pros and cons of those options-- was my biggest reason for joining the group.

WX at 162 MHz
Curtis, Tony
Thanks to all for the interesting responses on receiving WX at 162 MHz on
the '817. I like the idea of a downconverter as put forth by Dave and Pres. Down to 10m FM sounds workable. Maybe W4RT Electronics could make a teeny little wart for the back of the '817. I think the idea of using a separate HT or WX receiver defeats the purpose of getting it all inside one radio. Listening to FM broadcast doesn't defeat that, however. Also, it is correct as someone mentioned that airports have local WX broadcasts for pilots. For example, here at Cincinnati, the international airport has our friend, the computer voice, reading reports continuously. For arrival flights, the freq is 134.375. For departures, the freq is 135.300. I know there was "buzz" at Dayton about the '817 being engineered for Japan, but I don't think so. Why would they do that knowing the larger global market is out there? Doesn't strike me that engineering for just one country would make good business sense in today's world. I'm sure they wanted a quality amateur product and figured that increasing receive bandspread would introduce compromises that would reduce the overall quality of the rig. --Tony K3RXK k3rxk@... |

Re: MP-1 Mobile/Portable/Pedestrian SuperAntenna for FT-817
Thanks, Demetre.
I did download the W4RNL article but it was a bit much to get my head round. It is a very long time since I did school physics and learnt about fields and stuff. All I actually wanted to do was find a way to tune the MP-1 so it presented a good SWR and I could use it with the 817 without a tuner. Due to the intemperate diatribe directed at me by another member of this list I no longer wish to contribute, so I shall unsubscribe now and let you carry on discussing computer software and opening up receive coverage and similar matters in peace. Perhaps in a few months I will once again be able to go up in the mountains and use my 817 as I intended, and perhaps one day, Demetre, I shall have the pleasure of a QSO with you. Until then, 73.

Re: MP-1 Mobile/Portable/Pedestrian SuperAntenna for FT-817
Well, you have just rubbished the advice given by manufacturers like
Cushcraft, HyGain and others for erecting their verticals, not to mention vertical wires, end fed wires and others read in books. It is no good my trying to understand the technical explanations for these things, it is all way over my head.

understand things if they are explained in layman's terms. Surely, in an ideal situation, with a perfect ground, the ground acts as a constant reference point and all the RF energy will go into the vertical radiating element? With a less than perfect ground, there will be some loss, because some of the RF is trying to energise the ground as a radiator. If the ground is in the form of a counterpoise there may well be radiation from it, which may even increase the signal. But this is an accidental effect of a badly designed system. Improving the RF ground should increase the proportion of the energy radiated by the vertical element, giving among other things a less distorted radiation pattern. At least, that's how I see it.
