Post subject:  DIY multi band radio receiver

Hi there. I have recently acquired a Audio Selector Panel out of a Boeing 767 aircraft. I am wanting to strip the guts out of this and make it into a multi band working radio say from 80mhz to 136mhz range. I would like it to have a digital frequency display and also if possible a couple of channels of memory that can be changed by use of several push switches. However I have no idea where to start with building this. I'm a begginer to the whole radio game. I was hoping someone would have some advice for me or some circuit diagrams for a multi band receiver. That has some memory buttons.
Thank you

I have not much idea about RF stuff either, there should be allot of resources online, have a look and search up.
Try to do things step by step, learn absolute basics most simple stuff, build something and get exprience, don't just jump steps cause you'll fail and you don't learn much or anything from it.

Hi Tyza,

The purpose of an aircraft audio selector panel is to enable the pilot to select the required audio peripherals (e.g. microphones, headphones, speakers etc.) and equipment (e.g. radios, public address systems etc.).

At the outset, you would find no components that you could salvage from the panel to build a VHF radio.

Secondly, it would not be advisable for a beginner to select a VHF radio for a first project. A go at crystal sets and then MW / SW TRF, direct conversion, regenerative and super heterodyne sets would lay a very sound foundation for you to venture into VHF FM radios.

So sorry for my much-delayed response!

Good luck!
