Keep checking the Facebook link guys as more progress has been made Today. Only the Mic and audio pot to wire in as standard. Hope to be adding a 6 pin mini din socket for data modes and an S meter sensor.

That was thirty meters, CW. I like that band very much and will likely enjoy it more once we have returned to coastal Virginia, and my tall trees for antenna support!  CW , like small, seaworthy sailboats, become MORE useful as weather and infrastructure deteriorates:  "Anti-Fragility" in action.

I'm lusting after a Nextion display but it won't work with this case.  I wonder if Sunil has thought about different front plates laid out for different displays.

Nice, what band? CW?

id personally like the option to drop the power

Good point, I know of no small QRP rig with a low (lower!) power option... Great idea. It probably hasn't been implemented because of the extra circuitry. Often, dropping voltage will do the trick...

I was getting out to S. California on about 150mw.

That is amazing Joel. It really shows that sometimes it doesn't take much.

Thanks for your input guys.

Antennas / Re: MFJ 971 vs LDG Z-817

I just bought the Super Antenna MP1DXMAX Dual HF plus 2 meter Bands SuperWhip Tripod All Band Antenna with Clamp Mount and Go Bag through Amazon prime.
My go bag radio is the 817nd with the lg auto tuner, also have the 20 watt goal zero portable solar power system witch includes a converter so I can directly plug in my radio like a wall mount.  Going to put it all together and try it and will post my results.

Looks great Andy, I love that gray finish. I wonder if a blue display might not look really sharp with the gray case. I just received my AGC and Click/pop kits today so I'm going to start in on building them and modifying my uBitx board Monday morning. I could put up with the pop every time I let go of the PTT, but this radio really needs AGC, so looking forward to finishing it. Keep us posted on your results.

It's arrived and I've made a start.

Lots of work to do but I'm out with the band tonight so I'm chilling this afternoon.

Once again, I enjoyed a nice chat in Morse with AH6V who lives on Hawaii.  Listening to his previous conversation, he mentioned that he is 45 miles from the volcano, so no trouble. Electrical power is no issue for him, because he has been living off grid for decades.  His antenna is a dipole, high and in the trees and my antenna is not at all good for long range, being a full wave , horizontal 80m loop up only 5 meters at the support poles, sagging to 3 meters at some points in between.  We discussed his large solar power system, which powers even his refrigeration & etc. -vs- my small sailboat sized system and the work shop/ham shack that it powered. 

Radio is simply amazing and the BEST 'communications computer' is your brain.

Gil,

I know you are talking about CW as the mode however.....

 In 2015 I was building from scratch a Beach 40 DSB transceiver dead bug style on a piece of PCB. This radio was designed by Peter Parker VK3YE, I had just finished the receiver section, and the pre driver, and driver section, but was having problems with final amp going into oscillation, so I disconnected it. It was putting out about 300mw into the LPF measured without the final in the circuit. I was listening to a guy running a special event station aboard the Queen Mary docked in LA Harbor a distance of almost 1000 miles for my Oregon QTH while making the last connections to the mic amp stage with a electret capsule just hanging from some wires on the bench. I kept saying my call while looking at the waveform on my scope, Yep you guessed it, the guy returned my call sign and thanked me for checking into the Queen Mary. He gave me a 57 signal report with great audio. Keep in mind, I was running Double Side Band which means half of my power was going to the opposite side band, so that means I was getting out to S. California on about 150mw. You never can tell where your small signal is being heard. BTW, I had a lot of fun with that radio after I got the final amp section fixed, I made hundreds of contacts including one to Japan, all this on a bout 3 watts.
