Re: 6 Meters
I have had the same general observations, but last night I discovered
something new. I was playing around with my new '817, and had the rig sitting on the desk, with the "long" duckie connected with a right angle BNC adaptor. Suddenly, I noticed that the duck was exhibiting low SWR. After a bit of testing, I realized that the SWR was low with my straight key plugged in, but high with it disconnected. I was puzzled at first, but then inspiration hit, and I realized that the key cable must just happen to be the right length to form an effective counterpoise. I grabbed the counterpoise off my homebrew 6m L-network tuner and clipped it to the rig, disconnected the key, and whistled into the mike. Low SWR (no bars at all)! Regarding the effectiveness of the duckie for reception, I have the following single observation. I am anxious to test this further as soon as we have another 6m opening: While I was in the middle of my SWR observations, the squelch broke on my FT-736 (10 watts on 6m to a 5/8 wavelength vertical), and I made a couple of contacts into 5- and 0-land during a brief Es opening. I also spent about ten minutes working a 7/mobile 0 who was about 5x1 to me and who was receiving me about 2x1. After we completed our contact, I went back to the '817, and realized that I could hear the mobile station about as well on the '817 + rubber duckie sitting in the basement as I could on the '736 + vertical. Now, as I say, this is a single observation, and maybe my 6m feedline is full of water (!), but I'm going to test this further. On the next 6m opening I'm going to take the '817 + duckie + counterpoise out in the yard and see what happens. Meanwhile, I would like to encourage others to try to do some 6m operating with the duckie + counterpoise and report your results. (I remember a Christmas Day openining a few years ago, standing outside just before sunset with my IC-502, at about 7000 ft. MSL in Idaho, near the Wyoming border. It was COLD, but I had no trouble working into the midwest with three watts and the built-in whip.)

Re: Random Wire antenna

I know works. I have a 15 meter dipole (approximately 23 feet overall length) center fed with home made open wire line directly into my Z11 tuner. No balun, I just soldered the open wire to a PL-259. It loads on all bands from 40-10 (maybe 6, I haven't tried it). It doesn't seem to be too efficient on 40 but it works quite well 20-10. It's only about 8 feet above ground but I have worked all over Europe, South America and a couple of Japanese contacts. No 599 signal reports, but solid contacts. ----- 73, Rich - W3ZJ www.w3zj.com -----Original Message-----

Re: Modest output HF amplifiers.
You could also look at RM products in Italy. They do CB (25-30Mhz)
amplifiers , but also VHF and UHF and some have HF capabilities. Power from 30W-to 500 Watt with 1-7W input. Look at model KL203 and KL351, but also KL300 offeres 3-30 MHZ capability. The cost are really low for Europe (approx.50EUR) and some modification or filtering could also improve linearity. At least it is a good kit to start with. see: www.rmitaly.com product section vy 73 de oe3mzc Mike --- In FT817@y..., ve6szr@r... wrote: Ok, ok, at the risk of angering the QRP gods, getting flamed, orfor use with the FT-817?been perfect, but I don't think it exists anymore. |

Re: FT-817 + 50W Amp + Battery (/PM)

The reason for the SG237 Smartuner to start the tuning process again might also be an old software in the EPROM of the 237! You can write to SGC and ask for a new version that makes the tuner more stable or you can use the SMARTLOCK feature.

Headphone/Handset/Earphone/Headset/Speaker-Mic/Monophone?
Rami oh6bi wrote:
if there are any monophones built for 817,Rami, we have an American English translation problem. I think monophones are not monophonic headphones. Please tell us... What are monophones? Here are some American English Definitions... -Earphone (RX): Miniature speaker placed inside the ear. -Earbud (RX): Miniature foam-covered earphone. -Headphone (RX): Small speaker placed against the ear. -Handset (TX/RX): Telephone style hand unit PTT. -Headset (TX/RX): Headphone with small flexible boom microphone attached. -Speaker-Mic (TX/RX): Microphone and speaker in one hand unit PTT. -Monophone: ????????????? IMHO... An excellent aftermarket accessory for the FT-817 would be a small waterproof speaker-mic with a Heil mic element. The FT-817 speaker-mic cord would end in both an RJ45 and a mini-phone connector. The Vertex VX-1200 has an excellent waterproof speaker-mic with a mini socket on it for an optional earphone. I certainly have found the VX-1200 speaker-mic to be a very convenient device for hiking (pedestrian mobile). Bonnie KQ6XA |

I've tried mine. Stereo phones work fine. Sound in both ears.

Re: Monophones for 817 ?
No adapter needed. If you look at the schematic, you'll see that the
jack is wired to accept either mono or stereo headphones. And if I understand the original question correctly, the answer is you can get several models of monaural in-the-ear headphones from Radio Shack. They seem to work just fine. Or, you can get a Heil PRO-5 headset. I have an old BM-5, which is Heil's lightweight headset in a one-sided model, which I think is just about perfect, except when wearing a helmet. They aren't, apparently, made any more. And, after I return from traveling, I'm going to try a telephone headset, one sided, back-of-head band, and noise-cancelling mike with my FT817, with the intent of using it for bicycle mobile. 73, doug From: kdiehl@...
