Well, you do know, don't you, that the original expression is "three days younger than dirt", which comes from the story of Genesis, wherein God created the Earth on the third day, and man on the

Thanks, Bernie I will look up a source for TTL-USB converter and get one ordered. This is gonna be fun! 73, Tony N0BPA

I forgot to add that it's easy to program a T4 in the Arduino IDE. Jack, W8TEE On Thursday, June 4, 2020, 1:14:17 PM EDT, jjpurdum via

Arv: Okay, now that we're this far, let's think about the software. I vote for the Teensy 4.0. It's about the same size as the Nano, has 41 I/O pins, 2Mb of flash, 1 Mb of SRAM, is clocked at 600MHz

Hans I support Steve K1RF ideas for a mini-QCX or micro-QCX ( uQCX) version. Make it so small and compact that mere mortals would probably not want to attempt modification. That way it would fit

Hi all I will give it careful consideration for 2-3 weeks and report back. 73 Hans G0UPL http://qrp-labs.com

Right on Dave! Enough suggestions already, Hans is only one guy. Gary W0CKI

Hey QCX groupies, Quit dreaming up all kinds of new versions of the QCX and let Hans concentrate on the QSX, now approaching 2 years overdue. Still patiently waiting.... Dave, W0DF

One extra consideration from me: Do not slow up the QSX rollout! 73 Evan AC9TU

Design considerations for Han's next meeting with the heads of his Design and Marketing departments: Pre-assembled SMD components with SMD components both sides of board to ensure smallest possible

Hi Ken, If you are running milliwatts then a few more milliwatts isn't going to lift you out of the noise if you are struggling. It takes a fourfold increase in output power level to gain 1 S

Hello, thank you for starting this discussion. I am in a similar situation. I am waiting for the QSX as my first rig (I am quite tempted to buy also the QCX+, even if I am not interested in morse

Where does one find the serial number of a QCX?

You will need a TTL to USB or TTL to RS-232 converter. The QCX+ has the CAT interface already built in. You can also use an Arduino Uno as a USB to TTL converter. The Arduino program was posted

Hi Tony, Those boxtops are how I got my ham ticket (or so I have heard). 73, Bill KU8H Bark less - wag more ---snip----

Well, Hans How about a QCX PCB laid out for SMD. Happy to buy components from you, or gather them from wherever. Jim On 04/06/2020 14:32, Hans Summers wrote:

My perspective always has been the most efficient and cost effective way to package SMT parts in a kit are to have them presoldered to the PCB. For the few that really must solder them on to get
