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 soda to strenghten the bond. This is something I picked up on youtube.
It feels great to spin now. I got a spray can of flat black elastic rubber coating (the peelable kind) and most likely might use that to coat the knob and make it look nicer. 73 DU1FV

The unit was purchased used. Rather than a full-fledged HF machine, it is an entry-level radio if anything, but it is rig for convenient simple operation. 　In addition, we inherited the traditional TRIO Kenwood sound, even if I have listen for a long time, it is not tiresome to the ear. Device-specific problems are not inherited in the traditional colors of the TRIO walkie-talkie. Model number is also ◎ They discuss pulling the tradition of TS-600. 　It has come in handy and check the band condition, local ragchew, and mobile operation.

Hot-Rod Your ICOM IC-725-Series Transceiver by Jukka Vermasvuori

Hot-Rod Your ICOM IC-725-Series Transceiver Part 1  by  Jukka Vermasvuori   OH2GF Receiver Issues The receiver in my IC-725 exhibited these drawbacks: Its audio frequency response was too narrow, dropping 6 dB from its maximum by about 2 kHz. High-end rolloff that is this profound filters out speech energy necessary for good SSB intelligibility and severely muffles AM broadcast signals, which carry audio up to at least 4.5 kHz. 4 The AM-mode audio had a “mega bass” quality. The level of in-band intermodulation products seemed to be quite high. 5 On CW, I could hear weak phantom beat notes from out-of-passband signals. The pitch change of these spurs was the opposite of that of desired signals during tuning. In effect, a strong signal would come back into the receiver passband if I tuned in the right direction. Although these spurious signals were weak, they sometimes disrupted communication as I worked weak DX stations in crowded bands. During CW reception with th
