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.

QRP - When you care to send the very least!

Monday, May 22, 2023


 Congratulations are in order to John Shannon K3WWP and Tom Witherspoon K4SWL for being inducted into the QRP Hall of Fame at this year's Four Days in May event at Hamvention.

It's nice to see some of "the guys in the trenches" being recognized for their contributions.  John for his streak, super informative blog and his daily "diary" and for all his efforts to show how QRP, CW and simple antennas really and truly can get the job done.

Tom for his excellent blog and all his inspiring videos to show the way "to do it". How to go about portable ops the right way and the way he shows how equipment works and how to use it.

QRP-ARCI Leadership - thanks so much for inducting these two into the HOF. I can't think of any two more deserving!

An interesting video

 I stumbled across this yesterday


Several things stood out for me:

1) He had no real purpose for learning Morse Code in that he's not an Amateur Radio operator or intends to use it on a regular basis. He's learning Morse just for the experience. While I suppose that is a goal in and of itself, it seems to offer no sense of purpose or urgency, if you will.  When you're learning something just for the halibut, rather than because you need to use it, you can afford to be blasé' about it.

2) He practiced when he was tired. Not a good way to go about it, in my  humble opinion. Being relaxed is a good thing, but when you're dog tired, your mind wanders.

3) Even worse, he seems to have started off by writing down the dits and dahs and then decoding them as an afterthought. He seems to have abandoned that by the end of the video. The biggest error one can make in learning the code is to have any type of visual aid, unless of course, you're in the Navy and intend to be looking at blinking lights. I see charts and  other printed "quickie methods" for learning/remembering the characters. Those make me shudder. When you rely on visual aids, eventually you are going to have to "unlearn" them and rely on the sounds only. Might as well do that from the start.

4) If nothing, this young man is persistent. He doesn't give up even when he hits a wall and it gets hard. Kudos to him for that.
