Michael, In the Web page describing the transceiver it says, "New mono-band SDR transceiver AVALA-01 is ADTRX-2 transceiver with built in power amplifier and band oscillator all on one board." So it is mono-band. This is verified by looking at the schematic on page-4 of the AVALA-01 document from:
http://yu1lm.qrpradio.com/AVALA-01%20AND%20ADTRX2-YU1LM.pdf On the right-side of the above mentioned schematic, look where the antenna connects. The first thing after the antenna connector is a band-pass filter. Just under the schematic of the band-pass filter is a table of all the values you need for the filter components for EACH of the bands you wish to use. You need one separate bandpass filter for each band. if you wanted to cover 5-bands, you would need 5 filters. you can switch the filters in/out with a switch. Hope this helps...

I am still new to soft radio and am trying to learn as much as I can. I am a computer programmer and a ham so soft radio seems like a perfect fit for me. > > Michael > KC5HUB > > > ____________________________________________________________________________________ > Looking for last minute shopping deals? > Find them fast with Yahoo!
