Ring on the FT-77 knob Ring on the FT-77 knob As any rubber shoe or sneaker owner finds out soon enough rubber disentegrates with age but what happened to this forty year old radio vfo knob rubber is really something else. All of them by now have turned into a gooey mess and have to be removed for the radio to be usable at all. In the past, I have seen this happen to rubber belts on cassette tape decks. The problem with the now naked bare knob, is when you try to turn the knob faster, your index finger tends to slide off the knob. Not a good user experience. While I wait for a reasonably price VFO knob replacement I bought a $3 ring (probably pot metal just like the knob itself HIHI) at a sidewalk vendor in U.P. Town Center yesterday and today, I glued it to the old knob which had become difficult to use as my index finger keeps sliding off the bare knob. I used some tiny drops of super glue to tack it on and then used baking soda plus some drops of super glue on top of the baking sod

FT-77S  Personal restoration project, a vintage model released in 1982 by the  Japanese   Yaesu Musen Corporation.  Upon inspection, receive was poor and there was no TX at all. I took a look at the IF board and made some service manual adjustment for receive.  And now I can copy stations. After bringing out the scope I started poking around the IF unit and found some TX signals at the IF frequency. This signal is then fed to the RF Unit (shown below).     I then proceeded to checking out the RF Unit and found it had no TX ouput (which goes into the PA board).  So I had to backtrack. I started tracing the signal from the TX IF input J1011 of the RF Unit. Even before I started poking around the RF unit, I had a feeling that the print side of the board  might need reflowing at some places, (this yaesu came out in 1982!). Rather than blindly reflowing suspect joints, I just started tracing signals with the whole RF board upside down (print side up) and hanging in mid air with all connecto

Icom  "Nana Yonju"  ( IC-740 ) Repair The radio model is about forty years old. It is a little older and slightly larger than the more popular IC-735. It sits about in between the IC-730 which is compact sized rig and the IC-735, also a compact rig. The 735 sports an LCD display rather than the fluorescent display of the 740 and 730. What drew me to the IC-740 were the reviews on eham.net and other articles on it in the internet. I remember this particular comment by AB4OJ: " IC-740  - $200 to $250 - WARC bands, no general coverage, has IF Shift and PBT,very quiet frequency generation system" in his article "Good Older Icom Radios." (please google the article title.) I read of a defective radio up for grabs and made my mind up to try and get it. Buying a non-working radio is always a crap shoot but is the sort of thing that interests me most because 1. it usually is cheap and 2. it offers a challenge.   These are some pictures posted by the previous owner

    OLIVER X.A. REYES    |    May 24, 2017    In 1966,   The Beatles —the greatest rock band in the history of the world—came to Manila to perform. The reception we gave them then was less than ideal. Here is the story of how we repelled The British Invasion and lost our souls. In late 1991, a long silenced frequency rekindled on Philippine television sets with the plaintive chant, "Love, love me do. I'll always be true. You know I love you. So please..." The Associated Broadcasting Company, once the crown jewel of Philippine television, had started to broadcast once more, 19 years after its operations were shut down by President Ferdinand Marcos as he declared martial law. The dictator was afraid of the free press, of the Roces family that had owned not just ABC-5, but also the Manila Times. Marcos was ousted and now dead, so the station was now free to plead to the public once more, “…love me do.” The Beatles starred in the test broadcasts that ran for months on ABC-5 b
