progrock on power up

Chris Dunnett All Messages By This Member #19214 Hi All, I just completed assembling a progrock that I'll use in a QRP receiver. The user manual states that on power up the LED should blink 4 times and go out. Mine blinks like a CW 'D' (one long pulse followed by two short) and then remains off. Does this indicate a problem? As recommended in the instructions, I've grounded the 1pps pin. The voltage regulator (5.2V) and the noise filter (3.7V) voltages are within Han's 5% tolerance. My thought is that the timing between the first and second pulse is too short to perceive and they are blending into one long pulse. The LED turning off should indicate the I2C connection is established? I'm using the FOX924B TCXO on the Synth and am new to SMD soldering (can't figure out a way of double checking the connections, but the solder is very shinny). Also, can anyone recommend a ballpark reference frequency for the FOX TCXO? Best, Chris, VO1CKD.

Try a reset as in section 4.2 All I see is rapid flashes, so fast I'm never sure I've seen 4. But then I'm probably just slow.. The FOX will be close to 27000000 73 Alan G4ZFQ As recommended in the instructions, I've grounded the 1pps pin.

Chris Dunnett All Messages By This Member #19220 Hi Alan, I've taken your suggestion and done the factory reset but still the same issue. On power up, does the LED come on first then flash four times? Perhaps I'm just missing a flash. Hopefully the issue is with my eyes and not the unit - it does flash quickly. I'll plug it into the receiver in the next few days and see what happens. Thanks, Chris.

Alan G4ZFQ All Messages By This Member #19226 On power up, does the LED come on first then flash four times? Perhaps I'm just missing a flash. Chris, I've never really bothered, I had a counter on it and that confirmed it worked. But I've just tried counting, blowed if I see more than 3 but they are just short flashes. 73 Alan G4ZFQ
Mike All Messages By This Member #19228 Just a silly aside. Aldis Lamp signalling ( morse by light flashing ) maximum speed is supposedly a mere 14wpm. I'm not going to calculate the duration of a dit at that speed, but the Progrock is certainly faster. Hense the ambiguity between flashes observed at power-up. I think its three, but it could vary depending on the software.

Chris Dunnett All Messages By This Member #19230 Alan, I though of taking a video and slowing it down but...that just takes time away from building more radios. :) I'll check the synth on my home receiver tonight. So long as it works :) Best, Chris.

Chris Dunnett All Messages By This Member #19359 To followup, I found the issue with the progrock blinking three times rather than four: a sagging 9V battery I was using for testing. I plugged it into 13.5V from my Astron and it operates as it should. Thanks to Alan and Mike for their input. Best, Chris, VO1CKD ?

Keith, G6NHU All Messages By This Member #21299 开云体育 Mine does the same - Even giving it 11.5V from a good PSU, I get the three flashes. ?I’m able to program it successfully with the four flashes after each button press so I’m not too worried. 73 Keith G6NHU toggle quoted message Show quoted text On 11 Dec 2017, at 14:03, Chris Dunnett via Groups.Io <chris_dunnett@...> wrote: To followup, I found the issue with the progrock blinking three times rather than four: a sagging 9V battery I was using for testing.
