I want to suggest a new board:

"Morse Keys".

I have lots of links to put in there if my wish is granted.

For listening training, I am adding another semiautomatic bug transmission:


That's not a Vibroplex though, it's this one:

Nice! Did you continue using the Vibroplex semiautomatic bug?

I recently discovered this short video with the same kind of Vibroplex that I acquired in a USEC port in 1965, when I was a sailing radio operator. I estimate the speed here to be above 30 WPM, and it equals the speed I mastered at the time. I still own that Vibroplex, and the video inspired me to practice more so I can reach that speed again.

What I really would like to have is a wristwatch similar to the one you see in the video. It was for sale by a British company for about $200. Unfortunately, they were sold out by the time I had saved enogh to buy one.

Quote from: GRIZZLY on April 01, 2022, 10:17:38 AMIt seems the 818 is available in Germany, do you know if the yeasu warranty will apply worldwide ?

https://www.csyeson.it/de/content/23-5-year-warranty

This Italian company, with a website in German, offers 5-year-warranty (3-year-warranty YAESY + 2-year-warranty CSY & SON = 5-year-warranty).

The condition is that you must purchase your YAESU product imported to Europe and sold by CSY & SON or one of their representatives.

Quote from: GRIZZLY on April 01, 2022, 08:39:56 AMLike I said in the old topic on this radio, I think I will buy a Yeasu FT 818 ND.

Please note that this thread is a continuation of another thread:

Since you live in the US, maybe you could complain to the FCC and let their inspectors find the cause?

https://www.fcc.gov/eb-cmpls

Another possibility:

https://www.fcc.gov/consumers/guides/interference-radio-tv-and-telephone-signals

QuoteElectrical interference may also be caused by power lines. Interference caused by your power company's electrical equipment is normally continuous, and your power company should be notified.

A simple method of determining the location of electrical interference is by using a portable battery-powered AM radio tuned to a quiet frequency at the lower end of the dial. You should hear static or a buzzing sound as you get close to the source of the interference. The closer you get, the more intense the static will be.

If you cannot locate the interference source in your own house, check with your neighbors to see if they also experience interference. The source may be in their home.

If you cannot determine the source of the electrical interference, contact the customer service department of your local power company. Most power companies will investigate the problem and take steps to correct it.

Quote from: gil on April 30, 2020, 03:38:01 AMGood news, I was able to make digital modes work by bypassing HamLib and using FLRig for JS8Call!

I found that you made a video with that theme, too:

Thank you for the first two videos shown previously! — Here are their YouTube URLs, too:

Quote from: nofake on June 04, 2020, 02:25:51 PMI am looking for the service manual for the Icom ic251E and the wire diagram for the mutek frontend board.

1. Free download here (PDF): https://www.manualslib.com/products/Icom-Ic-251e-3963801.html

2. Check pages 12-19 in this PDF about "ICOM IC-251E + MUTEK BOARD":
https://worldradiohistory.com/UK/Amateur-Radio/Amateur-Radio-1983-07.pdf

I didn't succeed in finding the Mutek circuit diagram for you. I found these phrases at more than one site, probably what you didn't do?:

Quote from: undefined(1) FRONT PANEL

  • Remove four retaining screws and top cover.
  • Remove four retaining screws and bottom cover, disconnecting the speaker.
  • If you have a Mutek front end board fitted remove it now. MAKE NOTE OF THE CONNECTIONS TO IT! ***WRITE IT DOWN***
  • Remove the four front panel frame screws
  • disconnect the wiriing harness and remove the front panel. NOTE WHERE ALL THE PLUGS GO! ***WRITE IT DOWN***
  • Locate the orange wire linking the mode switch and the board behind the power control potentiometer.
  • Desolder it from it's present position on the mode switch and move it to the common side of the switch. That completes the front panel mod.
This example from: http://www.pa7es.nl/All_ICOM_mods.pdf

Put this exact search phrase (with quotation marks) into Google:
"If you have a Mutek front end board fitted remove it now"
Check the hits, even the picture hits, maybe something there will yield what you need. Good luck!
