Hi Hank, Bob G8VOI - My presentation does not cover transmitting with SDR as it was created around four years ago. That was before the first SoftRock kit capable of transmitting was produced.
There are some designs that might be capable of transmitting in the 87MHz to 108MHz band, but as most of the SDR activity on these forums is ham radio related, it is unlikely you would find very much information or interest in doing that. In most countries it would be illegal to transmit on those frequencies without a commercial license and approved equipment. 73, Bob G8VOI --- In soft_radio@yahoogroups.com, "hank smith" <hanksmi...@...> wrote: > > does this cover trahsmitting? > also has any one created one to work from 87 mhz to 108 mhz? > ----- Original Message ----- > From: "g8voip" <g8voi.reeve...@...> > To: <soft_radio@yahoogroups.com> > Sent: Saturday, May 08, 2010 2:02 AM > Subject: [soft_radio] Re: Implementing your own SDR? > > > > Hi Ward, > > > > I wish you luck with your presentation!
