Jerry, Looks the L and C formed a series resonant circuit at the transmitted frequency. Raj

Now the readings looks normal!

Very mysterious, looks like ball lightening. I have seen one right outside my shack window and it was a real treat! Raj

raj ;? I messed up twice on pin3=12 volt on rec. sorry had some people drop in while I was trying to post.

Unit is sold. Dennis KG4RUL

Ivan even if all voltages are correct the R141 can be open, please switch off power and check with ohm meter. Raj

That is correct, you count the pins in a clockwise direction. From your last readings things looks haywire. Please see the table I sent you by PM. Also when you reply please edit the previous message

Ivan, Check T5,6,7 .. it will be a solder problem or a short. Shake eaxh toroid while provinding a "hallow" in the mic and see if the power suddenly jumps. Raj

Yos, I was looking for a suitable metal case for the uBITX and ended up wandering down the mailboxes section of the local Lowes.? They had a slim upright letterbox, the Gibraltar City Classic, for

You can also set the default using File --> Preferences from the menu bar. I usually just create a directory for each project, placed in an appropriate subdirectory. Jack, W8TEE To:

FYI It is possible to forward bias the detector diode to get much higher sensitivity. https://goo.gl/mgZuYA Of course this does require DC power to the RF detector probe, or a small battery. Arv

Yvon I agree with you. I am similar to you. I used arduino for the first time. You seem to be similar to me. I have run only one IDE since I experienced something similar to you. There is no

John, Both the receive and transmit audio (monitored on another rcvr) were tinny. Maybe my original question wasn’t clear. Adjusting the BFO solved the problem. Thank you for your response. 73

thank you Ian. I have been writing embedded (?) software since the pdp8. And I am still working and writing embedded software (pic32 and ARM). What bugs me with the Arduino is the lack of proper

Bill and the group, Thank you. I did the BFO adjustment and what a great improvement. I am located in Glendale, CA just north of Los Angeles near the Rose Bowl. My first contact was to Tucson, AZ

all first. Congratulations on solving problem. I have seen this problem very simple. And the correct answer to that question was Mike's answer. The cause was the wrong eeprom value. ok? I saw an
