Yep. PRESET was added as a "mode" in the last firmware updated released a year ago. When it's active, it overrides many settings in other modes. The main problem is that if is active, it doesn't de-se

There is a notch button for MAIN and one for SUB. The MAIN notch button is in the MAIN row of controls below the SUB row controls.

I've added separate decoder and keyer speed settings as item 51 on my wish-list. Better yet would be if the decoder would auto-detect speed. I'm almost exclusively CW so only tried the decoder a coupl

S.MENU, SPEED sets waterfall speed. SLOW1 gives 20sec history in the waterfall.

IMO, the 3DSS is not useful and is just a gimmick. A waterfall better displays the same information. Averaging in this case means in the frequency dimension so that instead of just seeing single pixel

Yep. That's what I do. I put some rubber bumpers on the sides to keep things nice and evenly spaced.

There is a row of intake vents along the front edge under the radio, though these alone are insufficient, IMO. Opening the radio or studying the diagrams in the Tech Supplement, it can be seen see tha

Be aware there are air intake vents on both sides of the radio. I leave ~1cm on each side. If you call Yaesu USA, they will advise the same, despite marketing photos that show otherwise.

Yep. I characterize Apple as being imperious.

Yes. A classic approach is to turn RF gain all the way down, then AF gain all or nearly all the way up, then use RF gain to control volume. This reduces the RF needlessly going into the filters and al

If by patch cables you mean short coaxial PL259 or BNC jumpers, I've always made my own. I like the ability to control the exact length, quality of the cable and connectors, and know who to blame for

The FTdx101 has two complete and completely separate receivers, each in its own compartment in the chassis on the bottom side of the radio. They only differ in that their IFs are slightly different to

Personally, I think that was a very good idea years ago, but nowadays, with the various layers and of controllability of filtering on today's rigs, further filtering by using phones with restricted fr

If you want to hear one RX in both external speakers, you will need to adapt a single output to drive two speakers. What I do is take the two-channel headphone output and use a switch-box/amplifier th

If the RX buttons are green for both SUB and MAIN, you hear sound in the speakers as I described it. If only one is green, you get sound only from that speaker.

I played around with this and find no way to do what you're looking for on the rig itself. I agree it would be good if RIT worked for both rxs when in SYNC mode.

How it works is described in a table on page 16 in the manual. There are two external speaker jacks. Basically, if you plug one spkr into jack A and one into Jack B, you get SUB on A and MAIN on B.

I've been using Sony 7506 headphones for ~20 years with any number of rigs, including the FTdx101. Comfort and sound wise, I like them a lot. Nominal impedance is 63 ohms.

Yep. I see that now. I very rarely use MONO mode and even less frequently with both meters showing, but it's clear the second meter is obscuring the left edge of the pass-band. As far as flipping for
