I be tempted

 I'm not sure whether to give a tip o' the  hat to Bob W3BBO for bringing this to my attention or .......

Meet the QMX from QRP Labs.

Its a 5 band multi mode QRP transceiver. Currently it only supports CW and the digital modes, but a future firmware update should include SSB. Here's a rundown on the features:

80, 60, 40, 30 and 20m

CW and FSK Digi modes

All features of QCX-mini (VFO A/B/Split, RIT, Message and frequency memories, beacon, keyer)

5W output at 9V supply (can be built for 4-5W at 12-13V supply)

SWR bridge built in

Single signal transmission (zero unwanted sideband, zero residual carrier, zero intermodulation distortion)

Solid-state band switching and transmit/receive switching under CAT control

High performance embedded SDR SSB receiver with 60-70dB of unwanted sideband cancellation

Built-in 24-bit 48ksps USB sound card

Built-in USB Virtual COM Serial port for CAT control

Si5351A Synthesized VFO with 25MHz TCXO as standard

Easy to build single-board design, Professional quality 6-layer, through-hole plated, silk-screen printed PCBs

All SMD components factory assembled

Connectors: 2.1mm power barrel connector, USB B (for audio and CAT control), BNC RF input/output

Built-in test signal generator and testing tools

Switched mode regulators

Receive current 80mA, Transmit current 1.0-1.1A for 5W output with 9V supply (around 0.7A for 5W with 12V supply).

Optional aluminum extruded cut/drilled/laser-etched black anodized enclosure

All at a price point of $95.00 (kit form), as you can also order one pre-assembled. If you purchase the kit, the enclosure is available for another $20.00. Pre-orders only at this time.

This little rig has me in a quandary - I'm a bit disappointed that 17 and 15 Meters are not available, but I'm tempted to purchase one nonetheless. I could see this little guy becoming my main portable ops radio, significantly minimizing the size and weight of my current "go bag".

I'll have to think seriously about this one.
