Thread-topic: [CRTech] FM receiver modules?

In general, it is possible to connect USB devices into various mobile devices with the right adapters:  Many android and iOS devices can make use of OTG adapters (android) or the Apple USB camera connection kit (iPhones and iPads), to attach standard USB devices into the Micro USB, USB-C, and Lightning ports on those various devices.

 

It doesn't work for everything, in every instance, with every device, but many things do indeed work.

Isn't it USB only? How many cell phones have a USB port?

Not very basic, but this displays signal strength in dBuV.   Very nice for relative comparisons.  Also measures much else such as modulation, RDS sub level, pilot level, decodes RDS, etc.

To the Braintrust:

Are you aware of any inexpensive, very basic, analog FM receiver modules? The goal is to come up with a simple "relative" field strength measuring device for fairly strong FM radio signals.

I've tinkered with a 2-transistor design with a single tank circuit front-end, that "kinda works", but I'd like something more selective, and a bit more sensitive.

Ideas? Links? :)

Meanwhile, a-Googling I will go. ;)
