Started with ch 16 LSB back in the 23 ch days. Got you closer to the "hallowed" RC gap between 15 and 16 (.145), and a bit farther away from the heterodynes on ch 17 when the band was open. Irrelevant these days, I suppose.
Can you try both on an external speaker? I think you may just have to accept that the 6a is a wideband, but compromise, receiver. It does a lot for a small package. The 710a probably (not sure-look at the specs) has a tighter front end; the price difference alone would justify the better...
I just did a repeater search around your callsign, and the W4OE repeater is indeed at 146.925! Never ran into those out here in Texas. My bad assuming it should be .920!
Next step - were you using the same antenna to test both radios? Also, look for a 440 repeater to test against.
There was a WARC band kit for the 180. From what I've read, it took several coils and other misc. parts. Based on that, I think you are outta luck unless you want to hack the PLL circuit, and then you would probably take out the other bands as a result. It doesn't appear to be a simple...
Depending on the filtering (and other characteristics) of the radio front end, one radio may sound better than the other when receiving while off-frequency. Wide filtering vs. narrow...
Try comparing when receiving on the "center frequency" of a known repeater.
47W784... or as I used to say, "Nasty Monkey" 784 (New Mexico 784). Haven't used it since 1983! Had more numbers than I can remember, favorite was IRS #00 (Illegal Radio Station Double Zero).
Looks like some euro youtube vids are showing up, just search for ic-9100.
Here's one from a week ago:
YouTube - IC9100 2656
There's also another from Germany talking about various "issues":
YouTube - my new IC-9100 (first one in Germany)
$3799.95 at Universal. Ouch!!! :ohmy:
Did you verify the -15v and +15v? (can't tell for sure if that's 15v or 13v). Looks like vr7 may be what you need to tweak. Check the -15v, you may need to drop vr7 down a bit. vr4-6 look like they just adjust the top end of the scales. Also, make sure that none of the capacitors in the...
