the radio needs to be aligned. The VCO may be unlocked.

What ever is not in alignment is off ever so slightly so that when you turn it on, its off freq, but once it warms up it is on, because some parts will slightly change values due to heat or temperature change.

It may also be a resistor that is loosing its value some where in the mixing circuit. Its off until it gets warm because it is going bad.

If you know what you are doing you can track it down with an ohm meter. Each color code is a different value. If the resistor is not what the code says it is, then there is a problem.

You should take it to a tech to have it aligned. In most cases, because its of and or the VCO is off, it can drift until its been aligned again and the VCO is locked up.

If you want to talk on AM put it on AM if you want to talk on SSB then put it on SSB. Did you recently purchase this radio? You do realize you need a ham radio license to use this ?If you are on the upper ham bands you better have a license or they will come and get you .Look at the the dial that has 1 - 7 on it. Now take the owners manual and look at the diagram of the knob . It should say something about frequencies and the frequency you need to operate on is from 26.965 to 27.405 MHZ .
