VE3XRM Radio Collection

Philips B7X44A/03 (1965)

I don't collect radios that are rare or in mint condition. I collect radios because I love to hear signals received by them. What you will find here is just a few of my radios, from ultra-modern to old and cranky. It doesn't matter what makes to go, tube or transistor, just as long as it can receive an electromagnetic signal.

All the photographs are personally shot by me (Ralph VE3XRM). (OK, I did photoshop most of them, mainly to control the size and touch up poor lighting.)

Note: Clicking on most images zooms to a larger photo.
Wait a bit, before clicking, while images load in background.
