I ordered another uBitx, it should be here in a few days. It will be the V4 board with some improvements incorporated into the new PCB. I will be using a 3.2 inch Nextion touch screen display on this one.
I'm going to make numerous case improvements to this one, like bolting the finals to the case for better heat dispersion. Gil, you wont like this one because it's going to have a higher idle current draw than the previous one, but it isn't intended for portable use.
I look forward to starting work on it. Ill post my progress.

I feel like have to defend the FT-817 :D I love my FT-817ND but I only use it for SSB and I'm very happy with the performance. I do have the Inrad SSB filter installed. YMMV.

General Discussion / Re: Have you tried the 160m band?

I always marvel at Peter Parker, VK3YE's videos running 160 meters AM/SSB QRP with a kite antenna and dipoles. https://youtu.be/ACiQlOThXR0 There always seems to be someone on the air in Australia and he always works from the beach with the wind blowing. It is a intriguing band alright. I wish I could try it out somehow, but kind of hard from a mobile home park.

A QCX for 160 meters :) Could you imagine how many turns you would need to put on T1?

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.

Morse Code / Re: The One-Watt Magic Number.
« on: June 15, 2018, 11:16:37 AM »
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.

Antennas / Re: MFJ 971 vs LDG Z-817
« on: June 08, 2018, 09:49:35 AM »
The LDG tuner is a automatic tuner and the MFJ is a manual tuner much like the one you already have. I agree with Jon, buy the LDG or just keep the one you have.

Good news Andy, you will love your uBitx with the CES 1.08 firmware. I use mine everyday and it just 'feels' like a real radio now with the new firmware. Those enclosures sure look professional, looking back I should have used one, it sure would have been easier. Please post pictures when you get done.

Great contact, a 57 is a good signal report. The vertical seems to be very quiet. Around here it is hard to find a place where the QRM is low enough to hear anybody unless I drive a long way to the mountains. I keep trying.

Hi Andy,

I had to do the same thing when I started working with 18650 batteries but I bought this  tester.

 https://www.ebay.co.uk/itm/1pcs-Constant-Current-Electronic-Load-9-99A-60W-30V-Battery-Discharge-Capacity-C/191883750242?epid=2024203215&hash=item2cad29ab62:g:mp4AAOSwintXSj2m

Works great.

Batteries & Solar / Re: Salvaging old Notebook battery
« on: April 20, 2018, 10:29:05 AM »
I used to be in the computer business and recycled hundreds of laptop batteries and now that I know about reclaiming these 18650 cells I was only able to find one old pack which netted me 6 good cells:-(  I need to keep a eye out for some more, only now they seem hard to come by. Figures.
