How do you set push button pre-sets on an old style double knob 1978 Chevy Silverado radio?

Answer 1

On the models I've used (and maybe this is just an issue of word choice?) you do the following: 1) Select the 'station' or frequency you want to store as a pre-set by turning the right (tuning) knob. A) in older models, FM or AM doesn't matter, as the button is only "remembering" a position on the dial. B) in newer (but still push-button or 'old-style') models, the button will also switch between FM and AM, but each button remembers BOTH the band AND the frequency, but will not remember more than one station (I.e. The button wouldn't remember one station for FM and a different one for AM) on the same button -- except of course, if those two stations happened to be exactly the same linear position on the dial. 2) Pull the 'push-button' mechanism out towards you all the way (one click, usually) -- it may take a little more effort than you think or you way need to lift up slightly on the push-button to get it to move, especially if it's been a couple of decades. 3) Push the 'push-button' back in all the way -- the linear mechanism on the dial should not move at this point. 4) Test your new pre-set by moving the dial to the left or right using the right-hand (tuning) knob then pushing the same 'push-button' in. The linear mechanism -- if working properly -- should now move the dial to your new location and change the frequency to your chosen 'station'. On new (digital) radios in cars, of course, you tune in the band and frequency (and in some cases a 'bank' of presets [such as 'FM1', 'FM2', 'XM1' / 'SAT1', or 'AM1'] that you want to store then push-and-hold the chosen pre-set button (generally the radio will beep and / or flash the display and / or audibly re-tune the station once the setting has been stored) it may take up to three seconds in some cases for the setting to 'take' -- if you're having issues, hold the button in a bit longer until you get some sort of reaction from your radio and / or watch the radio's display to see if there is a message or prompt, as in many cases the radio may ask you if you REALLY want to change an existing preset, or the radio may need more information such as the 'bank' [again, meaning something like 'FM1', 'FM2', 'XM1' / 'SAT1', or 'AM1']in which you want to store the preset. Hope that helps!

Answernot sure if works on all models

select station and pull the knob fully. keeps memory.
