Re: An MP-1 that is very hot
Lynn VE3CSS wrote:
Sorry to hear of the odd problem with some MP-1's.Same here, Lynn. I have tried at least 30 different types of commercial and homebrew HF portable and whip antennas. My antenna of choice is now the MP-1. Successful portable whip operation is more dependent upon the operator than other types of antennas. It's all in how you use them that counts. Getting the feedpoint and counterpoise up above ground level adds 6~10dB or more. No manufacturer is selling a better performing or more versatile portable whip for the FT-817 at this time, as far as I know. Anyone tried a better one? Bonnie KQ6XA |

Rules of Thumb: HF Portable Power/Antennas
Relative Scale of Approximate Power and S-Meter Signal Strength
For Various SSB Transmitting Systems at Low Takeoff Angles on 14MHz (HF-DX) S9: 1kW + beam = 4kW ERP S8: 1kW + dipole = 1kW ERP S7: 100W + beam = 400W ERP S6: 50W + beam = 200W ERP S6: 100W + dipole = 100W ERP S5: 50W + high dipole = 50W ERP S5: 12W + beam = 50W ERP S4: 50W + low dipole = 25W ERP S4: 12W + high dipole = 12W ERP S3: 12W + low dipole = 3W ERP S3: 50W + backpack whip = 12W ERP S2: 5W + high dipole = 5W ERP S2: 12W + backpack whip = 3W ERP S1: 2.5W + high dipole = 2.5W ERP S1: 5W + low dipole = 2.5W ERP S1: 5W + backpack whip = ~1W ERP S0: 2.5W + low dipole = ~1W ERP S0: 2.5W + backpack whip = ~600mW ERP NOTE: Comparison is approximate, based upon about 6dB for each S-Unit, and starting with a kilowatt into a 6dB gain triband yagi. Low dipole is considered to be about 3dB loss, and a loaded backpack whip is considered to be about 6dB loss as compared to a high dipole. Source: KQ6XA 73---Bonnie KQ6XA |

An MP-1 that is very hot
Hi All
Sorry to hear of the odd problem with some MP-1's. For what it's worth I have had nothing but great results with mine. Running the 817 both portable and mobile into this antenna I have worked most of Europe and both coast of Canada with excellent signal reports. When I first put the 817 in my car I was running off the internal batteries at 2.5w and put the MP-1 on the trailer hitch with the c clamp...by the time I walked back to the front seat there was a loud F6 on the air calling CQ (10m). I picked up the mic thinking "fat chance" and he came back with a 5x7 report. I drove for about 2 hours and worked a dozen or more European DX. I arrived at my parents and took the radio and antenna in to show off the world of minature communications. Again, with batteries and the MP1 on its tripod with the counterpoise thrown out on the floor, my first contact on 20m was the Azores...all this from Toronto. It works well for me. Thanks Verne! 73 Lynn Hilborn VE3CSS |

Re: At least one MP-1 which is not so hot.
Gene,
I've never heard of a whip that could compete with a long wire for short skip (or any other propagation mode for that matter) There is nothing magical about the MP-1. It's still just a whip, and will perform as well as other whips it's size. Nevertheless, it can and does work the world. -- Brian N0KZ --- In FT817@y..., genemarshall@i... wrote: A few weeks ago I picked up an 817 and MP-1 ready to tackle portable12 miles away.

At least one MP-1 which is not so hot.
A few weeks ago I picked up an 817 and MP-1 ready to tackle portable
HF again. After calling and returning to CQs for about three days across a two week period, I had one contact under my belt: someone 12 miles away. I've tried all HF bands, and the MP-1 adjusted down below 1.5:1 on each band so I wasn't even using a tuner. Becoming pretty discouraged, I decided to throw out a long wire and see where I stood with that. Just as I did, I heard a CQ and the opr came back to me with a 589 (he was also in CA). Quite a change. Just as that QSO completed I had another contact and this opr. offered to wait around while I swapped back to the MP-1. After doing so he came back and said that he never would have responded to me initially as I was so far down in the noise. This station was in Sonoma County. Going back to the long wire, we completed the QSO. Needless to say, I'm a little sceptical about this antenna. This coupled with the fact that the 817 mount doesn't have the holes drilled properly so only two screws can be used to hold it to the 817. I emailed this issue, with photos, to Vern but it's been two weeks with no reply. I guess it's going to cost me a return trip to Livermore to get that resolved. Anyway, if anyone has any suggestions to offer on the performance of this antenna I'd appreciate it. At the moment I'll keep it in the junk box. |

WPX Contacts...
I saw Chip's comments on the success he had over the weekend with the
little rig. I can't top his record! But I did want to just mention that I, too, enjoyed contesting last weekend with the '817. Over a period of a little better than 10 hours, I made 60 DX (only) contacts. All but 4 or 5 were in Europe and the remaining few were in the Pacific (JA & VK) and South America. Three or four of the contacts were on 10 meters or 15 meters. All the others were on 20 meters. All contacts were with a (15 ft high) 20 meter dipole and no tuner. I was using my new CW filter which UPS delivered only a couple of hours before the contest began! It sure does help - especially when coupled with the movable bandpass. I made one contact at the end with the 1000mp just to confirm the fact that it is easier with the "big rig". It is! But there's no denying the special kind of fun that comes with doing it with the little fellow. I really appreciate how hard several of the guys worked in "breaking their rhythm" to allow the multiple repeats it occasionally took to make the contact. I never mentioned in any contact that the rig was QRP. Thanks again guys! |

I also have noticed the display flashing when the 817 is plugged into external supply, I am running the rig from a SLA gel cell. It also takes several attempts of switching the rig off and on before the problem clears. I cannot find any reference in the manual as to what it means. I look forward to any suggestions / explainations Ian, VK2ZCD On Thu, 31 May 2001 W4JZ@... wrote:

Hi David !
I was surprised how well the Outbacker Outreach and Alpha Delta Tripod worked, I have to admit it's nice to try a friends one before I buy one !! :) This weekend was the first time I'd made contacts across the pond using the FT817, so I guess the Outbacker had something to do with it as well :) Cheers!

Re: QSLs ...

Hi Michael,
I think the more people that use elctronic QSL systems the more pressure there will be on the ARRL / RSGB to accept them. Here's another though, I have received a number of QSLs printed via computer and then put in the QSL buro to me, they look no different to the ones I have received via EQSL and printed myself, so at the end of the day, who will know ???? Just a thought ! Anyways, back to my FT817 ! Cheers! MikeT ... Michael Minor wrote: to bad the ARRL won't except these cards for VUcc ect.

Display Flashes
When turning rig on display flashes on and off. I turned rig off and
on several times and that time it fixed the problem. I have not had this problem to occur now in several days. Rig is about 6 months old. I use International Power Supply and no internal batteries. Power supply is putting out 12.4 volts, I have the 12 volt one, and don't believe the power supply was causing the problem. I believe I read someone else had this problem, but I can't find the message. Any ideas what might be causing this or what to do if it happens again? I would guess a processor reset might fix it if it happened again. I can't find anything in the service manual or owners manual that seems to address this problem. Thanks, Reed W4JZ |
