go to youtube.com and do a search for: upd858 chassis: sensitivity enhancing

Thanks,
I never installed Adobe/Flash on IE. Forgot. I just open in Chrome !
Now to find an open source Utub down-loader . Might try the mod today on a Trc457. But
maybe to morrow. Its time consuming a Re-Cap. Then removing an old lower channel mod. Reconnect the NB switch.Then installing a digi-scan. And another frequency counter. Shotky-Diodes done. NB ressitor done.
Audio mod done. & lastly The SG hookup-oscilliscope & alighn-ment ! One last thing. Got a few TO-92 sockets from an old meter I found in the Trash. TR5. will have a socket.
I can then just plug in and out a bunch of low noise various VHF/UHF NPN Transistors I collected including the dubious 2sc2999
That video gave me ideas! Now to find the tripod for my 14MP cam !
