[bars] Back on the air

RF/Audio gain on 7300 I’ve had lots of experience with the past 5 years.  Nearly every You Tube videos demo bright rainbow colored screens cranked to the max.  light show for You Tube, but horrid for RF radio tuning.  Minimizing the RF gain you get very sharp defined spectrum.  Performance was improved immensely after I figured this  out.  The value of  SDR.

The IC-7610 works similarly. There’s so much in this radio that there are TWO manuals: Basic and Advanced. 

I’m still playing with the features.

IC-7300 and other rigs do the same. In the 7300 it also puts an RFG icon on the screen to let you know it’s not at maximum. Playing with this can increase signal to noise ratio and make listening more pleasant. Try it. 

Also you can plant the radio on, say, 28.400 the 10m calling frequency and turn up the squelch so the radio’s quiet until someone comes on. 

Downloading the full manual PDF and browsing it to understand all the functions is really helpful.

I happen to have read this part of my IC-756PRO manual yesterday.  On this rig RF gain and squelch are basically separate ranges in the same physical dial.  It is possible to configure the radio to always use maximum gain (knob controls squelch), or an "auto"mode where AM and FM get squelch control and SSB/CW/RTTY modes have RF gain control enabled.  At "noon" position basically gain is full and squelch is low.

In the comedy department, the manual says: "The squelch is particularly effective for FM.  It is also available for other modes."

I mostly run SSB on 10 and 20 so the knob stays at 12 o'clock position.

I will reply to this as it appears I am once again receiving the list.  Glad you figured that out Juan. But it depends on the rig. On my yaesu ft1000 the squelch does function in am/ssb mode.  And I have a 1973 vintage ftdx401 where the ssb mic gain is also the Cw carrier power adjustment.

I should know to RTFM by now.. LOL! SQL doesn't work because on this radio it only works in FM mode and the optional FM board is not installed. Mic/Drive sets power out in SSB mode. It does nothing in CW or FM. Weird. And it looks like the meter is not supposed to be backlit.  

So I guess the beast is working exactly as it is supposed to. <shrug>

Got the FT-77 connected and running. Amazingly, it works, with some exceptions. SQL adjust doesn't work, and output is a slight bit wobbly in USB mode. Settles down if I dial down mic/drive. CW works amazingly well. FM doesn't work, the board for it is an add-on and is not installed. In fact, it has no options installed. I was a bit surprised to see the CW option has to be soldered onto the main board. Backlight on the meter is also not working. I was heard once on FT8 but today is a nasty day for propagation. Solar activity on DXHeat is off the meter. The RF and noise attenuation work VERY well, better than on my 840. 

And.... justy now a QSO with US2YW in Ukraine. The radio does transmit well. :) I'm also happy to see I've passed the 50% mark for QSL's on my QSO's.  

I wish I had the test equipment and space in my shack to fix my 840 myself. It's going to have to go to a shop.
