[Discuss-gnuradio] selecting frequency for different daughterboards

[David Scaperoth]

hey all,

I have been updating some simple examples for receiving and  
transmitting FM signals I have made by adding option parsers in the  
scripts.

I was trying to make sure that when a daughterboard was selected  
(using the options parser), that if an invalid frequency was used  
(for example, if I tried to receive 100MHz with the RFX400), I would  
want to raise some kind of assertion error...or something.

well, I noticed that in the subdevice attributes there is the  
function "freq_range"

this works great for everything except the Basic Rx / Tx which gives  
me a range of 0-90GHz!! in increments of 1e-6!

I was thinking that this range reflects the values that the LO is  
capable of producing and using for down/up conversion, but in the  
source code you have used these crazy large numbers to suggest that  
any value can be used (for recieving and transmitting)...and on some  
level that's correct...for these daughter boards.  Why not just  
0-44MHz (which I think is the range)?

any help would be most appreciated.

thanks
