My original quest was about finding a rig to be used for my microwave (902 and up) transverters.  I currently use an old Kenwood TR751A that, with modifications, fits my needs to a Tee with the exception that it does not have a sound card.   In order to add digital capability to 902 and up I am currently sitting on the fence between two solutions:  Either purchase a new IF rig that meets these requirements (hence my quest) or just add a SignalLink USB, or as Chris recommended, the RigBlaster Advantage, to my existing TR751A (and yes, yet another box).   No decisions yet.

On to a summary.   The ideal requirements for my quest for a uW IF rig are that it has to have 2m, multimode, QRP (or good RF output power control as we only need a watt or two, not 100 watts !), and an internal sound card to support digital.   I would like to minimize boxes and cables.  Cost is a factor too.  

Based on what I have seen so far, if my tax return was larger I would buy an IC-705.  It looks to fit the bill.  Factoring in cost, being a retired guy on a fixed income, the Q900 that K0SHF has mentioned looks like a potential winner.  Lenny has a Q900 and is currently using it for his 902 IF rig.
