AZDT, perhaps things are a little backwards in your entry. 148.MHZ is 2m Band.
173 is outside the ham bands...

You need to use an older version of sharp...I'm running 1583.....ALSO has to be a 32 bit version of sharp.
I'm running it now..

-d is not a ser # .....even if you've reprogrammed the ser # of each new dongle
The # that's listed on the left when you do a rtL_test is the -d #.

I could come up with some good data like a climatologist if you could give me an idea what a good MTBF # would be :>}

If you have rtl_biast then you probably have rtl_eeprom -s ....you can change the ser# of the dongle. Help you figure out which is -d 0 -d 1 ..

I know its been a month ago you made your entry.
Whenever I see that reg read /write stuff on rtl_test. To me , it means you've got low voltage getting to the dongle.
Plug it into an active usb hub.
I've seen this a few times...always the fix

You could try to RMB and run as admin.
You could open a cmd window and change directory to where this file is and type the cmd rtlbiast. Then be able to read the error.

I haven't played the direct sampling lately which I believe that thing is using when in HF mode but I remember some complaining of poor reception. So, make sure whatever app your using that its in direct sample I or Q.... NOT in Quadrature. In direct sampling you don't need any lo shift of 120Mhz/ 1...

If you can get it to work at all..the answer is no.....but may help. I hope this helps :>} .....the antenna in the picture is useless for HF
