Hellschreiber coming in nicely 2256 miles all the way from SW Washington state to Florida using 500 mW. ?I'm transmitting “AA7US CN76XH AA7US CN76XH” on a 10 minute frame.

Good evening, I am trying to set up my U3S with the receive module and have 2 questions I could use guidance with. 1.? I have set up Park Freq and Mode params as per manual.? Do I also need to set

Glad you got there. Have fun ! 73 de Andy

Thank you Andy! Using slow Hellschreiber mode with the speed you recommended did the trick. ?It looks great. Yes... despite the reduced signal strength, a little beaconing variety is what I'm looking

Don't use lead free Euro-solder. That generally solves most soldering issues!

Following on, I have a hiss from headphones attached to output jack fed through the polyphase network board. I am able to alter the volume of this hiss. If I touch input pins of IC3, 4 and pin 5 of

Glad you got it going without too much trouble. -- 73, Bernie, VE3FWF

Two things, Check the socket pins for good soldering and insure all the flux has not gotten into the socket. (rise well with Isopropyl alcohol.) Allison

Pulled out the micro-controller and reseated it. That did the trick. Thank you so much everyone for the help Much appreciated. Andy G0OEY

*Hi Hans, Hi all ! By playing around with the GPS Clock Kit, i wondered, if nobody else than me has the wish to to be able to display the latitude and longitude in different formats. The clock

Try pulling?out the micro-controller and reseat.? If no joy, recheck all the solder joints and touch up as required. -- 73, Bernie, VE3FWF

Yes I have. Before it would start ok with a couple of on/off cycles.

Have you done the micro controller start up mod detailed on Hans’ QCX pages? Clint. M0UAW IO83 *No trees were harmed in the sending of this mail. However, a large number of electrons were greatly

I’ve had my 40m QCX built and working with WSPR for a while and decided it was time to try a CW QSO. All went fine, worked a local contact for over 30 minutes and then shut it down. Now when I

Ther's also a speed setting for Slow Hell. Needs to be about 17. This speed setting will tend to effect the aspect ratio of the characters, so you can tweak it along with the FSK settings if required

You need to use the Slow Hell mode for grabber work. Use an Fsk bandwidth setting of about 4 or 5 Hz. If my memory serves me right and there have been no fundamental firmware changes, then the U3

Thanks to all..... I'm using 350C and it seems to be be pretty similar to the 30 watt iron I had before. I appreciate all the input. 73, ?Robert KR4VT

Is anyone successfully using Hellschreiber mode on U3S with firmware v3.12a? I just tried regular and DX Hellschreiber today for the first time and am getting a splattering mess about 20 Hz wide when

Justin, For 2m you may find the phase noise fairly high.? Just listening to it bare with my?2M system suggests that. For 222 and higher its not what you want to use the harmonics sound bad! For 432

Thanks Bill, I appreciate the clarification. Brian VE7JKZ
