The only way to check swrs on ssb is to put a steady tone in the mic then calibrate and so on. You can use a cross needle meter too.
I don't understand how swr would change from AM to SSB being the frequency difference is only 1 kc.
His SWR, not swrs wont change from am to fm to ssb. The way it is read by some meters will when you modulate you throw the meter out of calibration thus showing a different reading. Why even attempt to try it on SSB with a steady tone etc when AM is available just throw a deadkey on Am calibrate your meter and go with it, that is your SWR no matter what mode you are operating.
his problem is that he is showing a carrier on SSB, as evidenced by the internal meter and an external meter.
the carrier balance control made no difference.
check out this thread:
at this point i dont know what the answer is, but maybe one of you can shed some light on this.
Modulation was 60% at max and had flat spot at top and bottom of scope
peak power was 2 watts swinging to 13
receive hadn't been touched
meter was WAY off an S9 would show an S3
Diode installed for?
cold solder joint on diode
PLL had 2 cold solder joints like it had been removed and replaced?
SSB carrier pot was broken
Tech said it looked like someone had attempted to install swing kit but forgot to put parts in radio.
Radio has since been fixed and works fine. So let's see I feel like I put my foot in my mouth for defending Sparky's. Refurbished DX949 peaked tuned and unlocked clarifier from sparky's plus shipping = $128.84 then add another $50.00 at my local shop to fix the radio so it would work correctly.
Many people swear by Al at Sparky's but this will be my last purchase from him and on top of that my wife bought this for me for Christmas and feels she got ripped off since I had to spend more money on it. :sad:
