Hello "iz oos", normally a vogad, such as the SL6270 or similar, is used as a dynamics compressor for microphone input, obviously, with the appropriate checks of in / out levels and coupling

Bob That was kind of what I expected, call it 3 or maybe even 6 dB, but perhaps you think a bit less. Now if you had a photoresistor, I find these can suppress a signal around 20 dB. Amazing to me

I tried the scheme with two computer switching diodes from the earphone lines to ground and it does work although not as effectively as I'd hoped. I'll prepare a headset to do this for me and I expect

Hi Mark, You're correct about CW mode not being a persistent setting in the stock software. No reason you couldn't save it somewhere, though. I don't recall about stock, but I know my software saves

Another question on the code. It seems like the radio does not save the CW state to EEPROM, just USB or LSB. Is this correct? In testing with my radio, I turned on CW and changed bands (so the

Curt, I just tried two 1N914 type diodes connected anode-cathode and placed it across the earphone lines to ground. I tuned to a net where there were several hams with one really loud and the others

I tried something a year ago or so. I was attempting to reduce the phase noise on Si5351 using an external oscillator instead of the internal oscillator. So, this is how it worked. 1. You take a 10

Hi, I have done and will be doing it again. When very loud signals suddenly appear in the cans, instead of making your ears bleed you will hear it suddenly very distorted and maybe a little louder.

Reed, Thanks. I new the gap under 256 was there for a reason, it just seemed odd that the numbering went from 257 to 358.

Following the calibration procedure for my v6, I had trouble zero beating a carrier, so I tried a modified approach that seems to work better for me. With the radio in LSB mode, I tuned 1 kHz above

Very interesting Jason! Tks! Rafael

Hi Mark, The EEPROM storage addresses have histories. KD8CEC's software for v5 has a bunch of other features and settings, so the location of the keyer config made sense when it was added, but was

Thanks Curt for your encouragement. I will try it soon and report to the group. Bob — KK5R

Bob I have seen that method used -- so give it a try if you have a pair of diodes handy.? I am trying to recall which rig I saw this used with.? silicon may work - but maybe some folk may use

For headphones, I wonder if two diodes with polarities reversed from each other across the headphone line would provide some hearing protection...? Or a pair of reversed polarity in series if the

Loris, would you think a vogad at the audio output could be a solution to save both sensitivity and hears to some extent?

As a follow up, as I read the code, it appears the parameters for LSB_CAL and SIDE_TONE stored in the EEPROM are not used in the version 6 code. SIDE_TONE is at location 12. There is a CW_SIDETONE at

Will do , Evan and Thanks Again for all the help and useful information you gave me . 73 and stay safe Ei2if dah de dah

Patrick, I am very happy that you were able to get your uBITX working.? The knowledge of helping someone really makes my day. Have fun and feel free to post any questions that may come up. Enjoy the
