No joy in 9 land

Try connecting the circuits common ground to an earth ground, like the AC outlets ground screw. Or chassis ground if it's in a BITX metal enclosure, and the grounded antenna is connected. I am working

Check out this topic: ?/g/BITX20/topic/5141699 ( /g/BITX20/topic/5141699 ) Could be that negative spike when the relay shuts off causes the fet to latch up? Put a

I know I have that right because I'm using a BS170 instead of a 2N7000 so I had to pay attention the the drain and source pins. The other think I've noticed is that it seems to behave differently

Check that you haven't interchanged the PTT and GND connections. 73 Allard PE1NWL

Can anyone help me figure out why this circuit doesn't work reliably with the BITX40? http://www.w1hkj.com/FldigiHelp-3.21/html/w5zit_rt_channel_page.html (

Paul ZS2OE Best way to answer this question might be to enter the circuit in question into a spice simulator and run the simulation with Monte-Carlo variation on each value. This will tell you just

Hi folks I'm busy with the PA part of of Sunil's Bitx20 Ver 3 and have a question about measured cap values. The 100 and 220pf NPO's are the ones in question. Measured values for the 220p's for

Hi folks I'm busy with the PA part of of Sunil's Bitx20 Ver 3 and have a question about measured cap values. The 220pf chip ceramics are the ones in question. Measured values range from 198p to 225p,

I had a hard time using the function menu but I think it's cause I was just taping wire to ground and didn't put a button on my it. The calibration Line was easier to use when just touching wires to

Looks to have been a false alarm. I just fired up the service monitor and tuned it to the freq I was currently listening to on the BitX. Zero beat. Tried again at 7.0000 and once again, zero beat.

Great. Glad to hear it. Must be difficult or expensive to get a cable where you are, to be motivated to find a work around. Never heard of a USB cable like that. Was it plugged into a un-powered USB

Congratulations! I made my first contact the other day with the project still spread out all over the workbench! Now I can't remember the call sign, but it was in Ann Arbor, MI. I'm in NJ. I was

BFO is generally around 11.9985, so for 7.0000 mhz on the display the VFO should be emitting 4.9985 mhz. The 25mhz reference crystal on the Raduino is probably spec'd at +/- 100 ppm (parts per

Thanks for reporting Peter, I guess the code for the old calibration method somewhen got broken, I'll repair this in the next version 1.14, to be released shortly. 73, Allard PE1NWL

Very nice setup btw! I guess you used dymo tags. My question is how dis you cut alu in order to place ?the lcd so nicely?

Finally managed to calibrate it by using the pushbutton connected to the orange wire. It appears that the old way or calibrating no longer works. Cheers Peter Sent from Mail for Windows 10 Sent:

Also for the record I’m trying to calibrate the frequency in the old fashioned way. Cheers Peter Sent from Mail for Windows 10 Sent: Sunday, 4 June 2017 8:22 PM To: [email protected] Subject: Re:

Where do you get your stickers for the labeling?

Hi I am having some problems calibrating my Raduino. I downloaded version 1.13of the Raduino software as well as version 2.01 of the s5351 library. I then set the IDE to Arduino nano and wrote the
