A couple of issues noted with latest .23 firmware


 

These are just data points, not complaints or bug reports as they each have only occurred once and have no clue how to reproduce them.
?
1 - in SWR/Tune mode, with a measurement in progress the reported SWR would fluctuate rapidly between a value of 1.0 and 2.0 regardless of the actual load impedance. Power cycling the radio cleared the condition and trustworthy SWR measurement returned.
?
2 - While sending a message from memory slot #1 with repeat 0 (continuous) and interval of 5 seconds, the audio ¡°freaked out¡± becoming ¡°glitchy¡± sounding and painfully loud. I had to rip out my earbuds before my brain melted! Again, a power cycle returns the radio to normal operation. Audio settings were AGC ON (with factory default settings), sidetone:relative, filter 300Hz @ 700Hz.
?
I¡¯m thinking of an external, analog, ¡°brick wall¡± type audio limiter to protect my ears from events like #2 above. When software goes haywire it can¡¯t be relied upon to protect you.

An old solution was a pair of back-to-back germanium diodes across the earphone Jack.?


 

For the fluctuating VSWR reading, did that happen to occur right after hitting a high SWR lockout? ('S' displayed next to the VFO frequency)
?
I've found that that random fluctuation happens both when the lockout has occured and you go directly to the antenna tune menu item (without going to menu and back to the VFO screen to clear the lockout), or when you try to tune with the keyer set to practice mode.

Yep, that is what I used to do as well. It is a dirt cheap and easy solution.
?
I had a radio that had the same style plug on the front panel that was for the CW key and the headphone and CW key plugs were right next to each other. Accidentally plugging the headphones in to the key jack was similar to the sound of a gun going off next to my head. I added a capacitor in series to keep DC off of the headphone coils (and to keep from keying the radio) and a pair of back to back diodes to stop the "POP!".

@N1TR no, I don¡¯t recall a high SWR trip before the ¡°wacky¡± reading.

This .26 firmware hasn¡¯t been great for me. Had the audio freak out on me again today while in the field. Had to pull the DC to switch the radio off. When I powered up again, the tuning steps had reset to 10MHz through 10kHz. Not having 1khz and better makes using the radio a challenge ;) I ended up switching to the KH1 to finish the activation.
