@@TheTechPrepper That would be so great! You tend to show things in a way and make it understandable. It might be that "big dumb gorilla" aspect that allows you to dumb stuff down for the rest of us.
Great Video.... I have 3 QDX's, 1 high band and 2 low band all built by myself. I have also built several for friends and repaired a few to boot. You need to be very careful and make sure you have a good antenna match before transmitting or you will cook the finals. There is zero protection and the BS170 Fet's are not tolerant of even a mismatch of 2:1 for very long.. If you are lucky, it will just blow the 4 finals or the damage can be much worse to the point of not being repairable. I do maintain a stock of BS170's (dirt cheap) but replacing them requires a certain level of skill. It is easy to trash the board if you don't know what you are doing You can lower the output power by reducing the input voltage all the way down to 7 volts. Don't go below that because the 5V LDO needs at least 2 volts across it for stable operation. Typical output power at 7 volts is around 1 watt on a properly tuned QDX and the finals are much more tolerant of a higher mismatch. Also do not exceed 12v(if possible) input to the QDX. Bad things can happen also. I just finished my 2nd QCX Mini and this version was built for 10m. Besides being a great CW rig, they do a great job running WSPR (and other beaconing modes). I have this new one running WSPR on 10m at 1W output and was spotted in VK land, KH6, all afternoon as well as all around the US into an OCFD @40ft. I suggest you join the QRP Labs groups IO. groups.io/g/QRPLabs/topics Lots of good info on the QRP Labs line of products. Plenty of experts to answer questions and even Han's, the owner of QRP Labs is very active in the forum. The only downside in dealing with QRP Labs is that they are in Turkey and they are very busy and some component availability is an issue and cause delays. My last order took 5 weeks to get to Phoenix. 4 of which was them waiting for parts for the various kits I ordered. If you are into building kits, their kits and documentation are the best I have seen anywhere in my 50 years of kit building. 73 de N5AQM
@ Took The 5th, I appreciate you taking the time to share your experience. What are the indicators that you have blown the finals? I'm running the QDX daily for 12-hours at a time, with a heartbeat every 15 minutes on normal mode. For power, I am exclusively running the TalentCell 3,000mAh battery pack. I connected it to my power meter yesterday and with a full charge (5 indicator bars), it's running at ~11.8 volts and by the end of the day (3 indicator bars), it's running at ~10.8 volts. I am getting anywhere from 3.2 to 3.8 watts RF output according to my MFJ meter. Should I be concerned? I plan to capture more metrics today. 73 de KT7RUN
@@TheTechPrepper Under your stated parameters, you should be just fine as long as you maintain a good antenna match. They can tolerate very brief bad mis matches. I have transmitted without an antenna for about 2 seconds without failure. I have also run the pants off mine on FT8 untill it got warm to the touch(not hot) and give it a rest but that is after 15min of back and forth at about 3.5w out on 20m. The Failure modes can vary when you cook the finals. 1.) Just no power out, not getting hot while transmitting. 2.) Above plus getting hot when trying to transmit. 3.) Above plus smoke. it will take out the reverse polarity FET, Q7 which I just jumper around plus literally smoke the power FET's. I think this(Q7) is only on Rev 4 and later PCB's but not sure on that. 4.) Above and it takes out the driver IC ACT08 and other devices. A goner if the 5v regulator fails. 12V on the 5v logic bus. Pretty rare though. I have been lucky with my 2 failures where it smoke Q7 and just the finals on the newest one and just the FET's on my Rev 1. Both times were my fault because of a bad antenna match As a side note, I have used the QDX to download beautiful Satellite Weather maps using FlDigi on 12mhz out of point loma in Ca. It also makes a great band hopping WSPR transceiver at reduced power(~1w) I run it thru a LDG Z-11 pro...

Thanks, Mike. You guys are the ideal distance to exploit the benefits of an NVIS antenna deployment. I had a feeling that the QDX, JS8Call and little bit of wire would be a winning combo for simple and effective regional communications. Keep us updated on your progress.
@@TheTechPrepper - I'm in central Kentucky and with 20W and a low end fed random wire with a tuner, I was able to make fairly consistent JS8 contacts with some stations (probably with good antenna) in Texas, Florida, Colorado and random contacts in Canada and the UK... and that was a couple of years ago when the band conditions sucked.

Message storage and retrieval is an underutilized aspect of JS8 that would be very useful in personal EmComm. I was excited to hear that you are planning to implement intelligent message routing in EmComm Tools. That's a much needed feature. I also wish there was a packet resend feature where the receiving station could request a packet that didn't decode to be resent for more reliable communications. That would allow longer messages to be sent. Because it's not live communication, the operator doesn't need to be fully involved as the slow but reliable messages could be delivered or routed automatically. The routing concept is similar to ALE - automatic link establishment. I also wish JS8 used another few bits for error detection to avoid the false decodes to improve message integrity.
Really? I can't believe that this feature is under utilized. Honesely, that is the most powerful feature. Well, the plan is to implement more streamlined routing and messaging just by automating some of the manual steps. I have no intention of forking or rewriting anything in the core application. Theoretically, adding this higher level of abstraction seems possible. Stay tuned for a future demo. ALE is still on my to-do list...I am waiting for ion2g to hit Ubuntu. Cheers!

The only thing that holds me back from QDX is the lack of VARA/Winlink capability. However, your idea of having a small always-on JS8Call station is very appealing. I'd need to find another ham laptop to dedicate to it, though, and I'm not needing the rugged builds like your Panasonics. Maybe I can find another Maestro Evolve craptop on eBay.

Morning, Denis. Everyone seems to call out the lack of VARA on the QDX. Personally, I wish it had that support, but I look at this as a different class of radio. I really think it needs to be marketed as a persistent JS8Call (and fldigi/flmsg) transceiver for long-running nets. For our group, I am recommending a $200 "all-in" station setup and just pair it with a $50 used laptop and a simple, home-made dipole that is parked on a desired band.

How is your antenna work at the 15 to 50 mile range? I have friend’s in this range that can’t here well with HF voice due to urban/city produced noise. Want to try this mode and antenna in this range with 3 to 5 watts of power.
I have not retried that short of a range. All the literature around NVIS indicates a starting point of around 30 miles. Depending on the band used. You are more likely in ground wave range with those those distances which likely require more power. The antenna is rated up to 50 watts for voice and much less for digital modes. Remember, this antenna is designed for low power operation. You may want to try a different antenna and may want to look at a delta loop. They require a large area, but seem to work better in higher noise environments.
I would love to see this implemented into Linux, most people have little to no clue how vulnerable Microshaft Winblows is since very few bother to read the EULA.

I find the QDX not reliable. You will end up blowing something inside and repairing it repeatedely. I blow the finals on the 2nd usage. Repaired it and set it aside in the storage box. Prefer a more reliable radio. HP2AT.
Edited: What kind of power source/supply were you using? I've been reading that you need be careful not to provide more more than 12V of input. I put my TalentCell on the meter and it outputs about ~12.5V on a full charge and will dip down to about 10.8V (when there are 3 of 5 light indicators). When I finish out a 12 hour day running the QDX I am in at the 10.8 volt range. Given that the QDX is designed to work with exactly 12V or just a bit less, I am considering only charging the battery pack to about 80% capacity (i.e. 4 of 5 led light indicators).

Doesn't JS8Call need accurate time sync? We don't have that luxury in a full grid down situation. FSQ does not have that issue.
There is a time sync feature built into JS8 that can synchronize the application's timing using heard signals. I use this in the field.

I find the QDX not reliable. You will end up blowing something inside and repairing it repeatedely. I blow the finals on the 2nd usage. Repaired it and set it aside in the storage box. Prefer a more reliable radio. HP2AT.
Edited: What kind of power source/supply were you using? I've been reading that you need be careful not to provide more more than 12V of input. I put my TalentCell on the meter and it outputs about ~12.5V on a full charge and will dip down to about 10.8V (when there are 3 of 5 light indicators). When I finish out a 12 hour day running the QDX I am in at the 10.8 volt range.
Given that the QDX is designed to work with exactly 12V or just a bit less, I am considering only charging the battery pack to about 80% capacity (i.e. 4 of 5 led light indicators).

Thanks for the feedback. The upper membership tiers have more perks such as earlier access to the limited products that I produce. I am still trying to figure out how to keep all the initiatives going while still providing value to each tier. Cheers.

I switched my station back to a JS8CALL station. You can practice message storage, and relay hops through it.
