Hi, Was busy with my Bitx40, and i saw "smoke". I replaced the Power amp. The receiver works, and if I press the ptt it clicks, and the ammeter rises to about 3.2A, but no audio output. Any help would

I called and listened up here in Western WA, and heard a station calling around 7:30 or so, but all I could hear was their faint CQ. Maybe we should move to JT65 or FT8? :P -- Ryan Flowers W7RLF ?

I was calling around 7 from northern BC, but I heard nothing. By that time, it was completely dark here and propagation appeared to be completely dead. I had been listening all day to the CQ WW on

Very poor here also. I did work a station in California but I couldn't do it with my 5watts. I used my 100 watt rig. I tried calling CQ on the BitX frequencies and nothing, so I cheated and turned on

Very poor propagation tonight. Only 2 QSOs with QRP power several with 100 watts as the band faded and then nothing even with 600 watts. Is anyone up for trying late afternoon or early evening? 73

9:09pm I can hear W1LY calling CQ right now… KM4YEC

Me thanks too, I will be on 7277 a little later. I have a 6 pm net to call on local repeater. WiresX c4fm running analog, #40780 room number. Ed W0OIC, Gracias a todo

I don't know if this isyour problem,but the critical frquency (which is the easily measurable part of the ionosphere: the highest frequency a radio- ionosonde station can send upwards (vertically) and

thanks for the research Willy. I just had 4 great QSO's with guys in PA, MD, WI and KY on 7.277. Started at 2148 Z to now at 2300 and conditions generally got worse and worse. The last QSO with PA was

No, he's still running the stock software (v1.01) - the basic sketch doesn't support the Function Button yet. For some reason his raduino enters the calibration mode at power on. This normally only

The "MG" in the Pixie schematic is apparently a reference to "MG Electronics": ? ?http://datasheet.octopart.com/SBT-1612-Jameco-Valuepro-datasheet-7268353.pdf And it's magnetic not piezoelectric,

Thanks Willy, I got it!? de Karl, KO8S

I have been looking at http://www.voacap.com/p2p/index2.html and the results are very much what I have been experiencing on QSO night. It is also a very good predictor of what other times might

Hi Jack, Allard's software with instructions is located at: https://github.com/amunters/bitx40 Hope this helps. Marco - KG5PRT jjpurdum@...> wrote:

All: I've been out of the country for over a month without internet and have two questions: 1. What/where is the latest release of Allard's Raduino code? 2. I think I remember that someone was going

Hi Karl, "MG" is a buzzer which can be disabled by by pulling a shorting tab. It produces a pretty disturbing tone. 73 Willy ktschwab@...> wrote:

You could feed Allard's sidetone square wave into the clicky type transducer from Adafruit. Or you could feed Allard's 5v DC signal that goes over to the 10k resistor into the modulator as a source to

The Pixie sidetone is generated by some sort of piezoelectric buzzer/sounder, rated to sound off when given 9v to 12v.? These generate a steady tone of maybe 2khz or worse when fed a DC voltage.

Regarding the need for something to monitor transmissions from the Bitx40v3 during testing, the SoftRock Lite II Combined Receiver Kit at $21 might be the best bang for the buck, assuming you already

A question on the Pixie; what is the "MG" component that is being used for side tone?? Thanks, 73, Karl, KO8S
