ProgRock2 is a triple clock generator (crystal replacement) with optional GPS discipline. It is available for $18 in the QRP Labs shop shop.qrp-labs.com/progrock2 . The freatures:
Tiny size PCB, a little smaller than an HC6 crystal: 0.725 x 0.675 inches (18.4 x 17.1mm)
Factory assembled, ready-to-use (no assembly required)
3 independent 3.3V p-p squarewave outputs (2 if you use GPS discipline)
You can feed the outputs through LPF kits to get sinewave outputs
8 selectable “banks” of frequencies, chosen by 3 input control signals
Frequency range 2kHz to 200MHz from onboard Si5351A or MS5351M
Extended frequency range up to approx. 300MHz if you don’t mind violating the Si5351A datasheet specifications
Quadrature output mode (Clk0 and Clk1 on same frequency but configurable 0, 90, 180 or 270-degree phase offset)
GPS frequency discipline using 1pps from a GPS receiver
Power supply voltage 3.5 to 12V DC
Frequencies and configuration stored in non-volatile memory for next power-up
QRP Labs Firmware Update (QFU) bootloader

Hans, You have done it again! Totally amazing and very functional. Brought a big smile to an old guy who built his first oscillator with a 6C4 in 1957. I look forward to receiving mine.

An amazing little piece of kit !! Love the Heath 1103 counter. Built one back in the day. Over the years I did change the 7400 series IC's to 74LS.. Was a great workhorse. I have 3 of the old prog rocks.. Those also are great. Graham VE3WGW

Love the nixie glow :-) I found this 1103 at Dayton the first year I went, 2009 I guess! 73 Hans G0UPL

Remarkable! So many uses. Thinking about a compact channelised CW rig, 8 channels across your favourite HF bands, could use IQ clocks with an H-mode mixer fora true single signal Rx, or use two clocks for a conventional superhet. Tx uses 3rd clock, 700Hz away, keyed externally.(wonder if screening could provide sufficient isolation 🤔). BCD up down channel changer,, program in popular QRP, SOTA, POTA,channels. Class,E BS170 PA. I get excited by concepts like this! Thanks again Hans. 🤓

Thanks Hans. Food for thought put the GPS and the progrock in a small box like the QDX box and create a bench test 10 MHz reference for instruments like scopes and spec ans. Keep smiling.

A better idea, run the Tx clock at twice the frequency and key a divider flip flop 👍 thus,keeping the running orc out of the receiver.

Well done, once again!

WOW. Maybe I am a simpleton, But I think my jaw dropped for about ten seconds when the video compared the size of a crystal.

Wow. Very Cool. Think I will "upgrade" my progrock 1 GPS standard to one of these. Nice work Hans. Tim - K5DEZ

Great.. I await the units. 0.25ppm stability was unheard of at consumer prices a few years back..

Now I have to find a use for a ProgRock2 in a Van der Graaf Generator.

I've been thinking of you since the earthquake happened. I hope you and your family are mostly unaffected.

Thanks, we are not directly affected, we live about 750km away which is far enough, even for such a large earthquake. Indirect effects are more widespread.
