Re: 857D-HRD disconnection on 40 mts
#cat
It has little to do with the SWR seen by the transceiver, but rather the RF in the shack. A few ferrites on the USB cable(s) and the CAT may help.
If you have one that you can make several loops through it increases the RF impeadance on the square, so make more than one turn if you can. |

Re: YT-100 Tuner Failed (apparently) - Need replacement Cable
Ron,
You were spot on!? It was the chip fuse.? ?I had terrific service from Yaesu in Los Angeles.? ? ? Sent it in on July 19 and got it back fixed on August 16th.? ?VERY reasonably priced as well.? Radio and YT-100 tuner work just fine again.? They didn't even reset my programming.? ?All the memories are still there.? Dennis N1TEN San Diego, CA |

857D-HRD disconnection on 40 mts
#cat
Hai all
When I tune my 857 and with my LDG 1000 pro-II, ant. tuner on 40 mts (Only 40 mts) the software gets disconnected. The dig. interface used is Link-5 (BY make) with CH340 driver. I feel may be some RF leak, but could not find it find out.. Request suggessision. Ant used is a Di-Pole with 600 ohms ladder line (home brewed) fed to TX through a 6;1 and 1:1 UNUN. The ant when used with the tuner gives a godd (less than 1.3) SWR on all bands.

You may look into the Yaesu SCU-17.? It is compatible with the FT-8x7 series radios and provides both CAT control and sound card interface for FT8 and other data modes. I've been using it with the FT-897 and FT-950 to good success. It comes with the USB cable to connect to the computer along with a cable for the CAT control and one for data.

Re: CAT cable recommendations

Re: CAT cable recommendations
I can confirm that the RT systems Yaesu-specific cable will work, and is likely the best option.
A warning: generic cables, and cables for other radios, such as Kenwoods, with the mini-DIN connector may connect the 13.8V pin to ground, blowing the SMD fuse on the board and making it impossible to power a tuner or other accessory. ?I experienced this on both my 897 and 857. ?You can (sort of) get away with it on an 817/818 because they use a current limiting resistor instead of a fuse, but it's best to use a Yaesu-specific cable.

I turn to the hive mind here — what’s the most popular cable? Will the RT Systems cable work with their programming software AND serve as a CAT cable with HRD? Thanks. Paul Braun WD9GCO Anchor, Amateur Radio Newsline Certified Music Junkie "Never follow anyone. Be your own hero." -- Neil Peart |

Re: Keeping the 857D Screen For Long Life
开云体育I live in Central Florida. I had my head unit mounted low on the front console on my Honda Element. It was always out of direct sunlight. I even had a soft cloth covering it when I wasn’t using it. After around 5 years of sitting in the car with internal summer temperatures easily hitting 130 degrees, my remote head developed zebra stripes. The problem seems to be heat, not direct sunlight. If I had it on top of the dash, it probably would have failed earlier. ? 73, ? --Hank KB4MTO / TA5ZC ? ? ? From:

Re: Keeping the 857D Screen For Long Life
开云体育From the sound of things, that could be as simple as a solder joint refusing to pass electrons until heat expands it.I've brought radios back to life, cured hums, and surprised myself on several repair projects merely by reflowing solder (assuming no overt damage, lightning events, operator errors, falls to the concrete, etc.). I'd look particularly at the battery area where you did the replacement. This is when being a ham becomes fun -- when you get to fix something!? Far more satisfying than mere operating. Good luck! 73, Kent K9ZTV On 8/12/2022 4:10 PM, PHILIP SHULLO

Re: Keeping the 857D Screen For Long Life
Interesting problem that is not limited to 857D. My 857D was purchased new in about 2005 and kept in my truck in South Florida. The zebra phenomena did occur the first time a couple of years later and I sent the transceiver to Yaesu for repair. It worked for a year or so and the problem reappeared. I sent it back to Yaesu and this time a different version of the display (though it looks the same) was installed. It has worked fine since then.? What I find interesting, however, is that I have a similar zebra issue with my VX-6 until it warms up. The handheld takes a few minutes of operation before the characters on the display become fully readable. The only time all the characters are fully present at "power on" is if the radio has been in the hot car or in direct sunlight for sometime. The problem first appeared when I bought a replacement battery as a back up for service events. It doesn't matter whether I use the original battery or the replacement, the radio needs to warm up before it becomes fully readable. It is annoying but something that I can live with. 73 Phil KI4LJP |

Re: Keeping the 857D Screen For Long Life
开云体育I just powered mine up to do an informal test. On first power, 17 of the pixel columns were blanked out. Over a period of about two hours, ten of them self "repaired" or "healed". This was with rig indoors at normal room temp. No transmitting, just power on, sitting idle.? I'm going to keep it on for the remainder of the day to see if any more columns come back alive. Is this an anomaly or is this what's seen on most with the zebra problem? Just curious...
