Choice of antenna and daughter board

hi,

can any body tell which is the antenna and daughter board that has to be
used in receiving FM…which is the best TVRX of Basic RX?

Oops… I meant to send this to the list.

Begin forwarded message:

Ok, that helps! The TVRX boards will be able to receive the FM broadcast band,
according to the specifications on the Ettus site (I haven’t used these boards
myself). So can the WBX (I have one, and I’ve used it to receive FM broadcast
transmissions). The WBX is more expensive, but it also covers a wider tuning range
and is capable of transmitting, in case you expect a future need for either of
those.

Any antenna or daughter board can receive FM transmissions. FM is just a
modulation type, and it can be used at any frequency, and with other
variations such as different amounts of frequency deviation. The point
of a software-defined radio is that it can send and/or receive any
modulation type within its constraints of center frequency, bandwidth,
and (in some cases) latency.

The question is, what frequency range do you need to be able to receive?
For example, FM broadcast band transmissions (i.e., what a car stereo
can receive) occur between 88 MHz and 108 MHz in the US. FM amateur
radio or commercial radio transmissions might occur anywhere between
around 27 MHz and well over 1 GHz. The frequency range(s) you need to
cover will determine which daughter board(s) might work for you.

Your antenna selection will depend on the frequency range(s) you need to
cover, as well as other constraints such as required polarization,
directional gain, etc.

So, what exactly are you interested in receiving?
