Re: FTdx101 Panadapter Shortcomings

Lou W7HV
 

Yes.  Having AGC slope and threshold would be a very welcome addition to the rig.  As with other radios that don't have these controls, two things that can be used to influence AGC to a degree are RF GAIN and WIDTH.  Reducing RF gain can reduce AGC action. This also serves to reduce the influence of very strong nearby signals.  For CW, reducing WIDTH can increase AGC action and improve reception of weak fading signals.


k2 and field day

Boy after using the ft -101d for a couple weeks now, mostly ragchewing in cw.
Yesterday set my K2,a battery and a end fed wire at 15 feet and a paper log,
to work emergency communications FieldDay. Worked great and many qso's.
 But what a change between rigs. Can' t beat the ft101d rx. and panadapter. Enjoy it very much.
Big change from years ago.

You can set the AGC time constants, but not threshold or slope.

Field Day with the 101d

Gary Schwartz
 

I operated from home yesterday strictly on CW for 4-5 hours and wanted to share what worked.  As a comparison last year I used a Ten Tec Omni VII.  Overall I found that I used the 101d much more because there was less fiddling with the controls and that it was less fatiguing to listen to.  My setup:  101d, external autotuner with 200' inverted V, N3FJP software, MORTTY (win keyer), paddles.  I started on 20 meters around 2:15PM.  Preamp 1 was on, width at 600.  The antenna was tuned once per band.  I was able to glance at the wattmeter and found the SWR foldback taking effect around 1.2:1.  At 1.6:1 there was a 10 watt power reduction, but this condition was only encountered on 80 where the antenna bandwidth is of course, much narrower.  The RF Gain was reduced to about 3 o'clock and the audio gain set to headphone listening level.  Interestingly, both of those controls never moved during operation on any band.  That was clearly not the case with the Omni VII.  On 40 and 80 the IPO preamp setting was used.  

Full QSK was flawless.  The noise and signals never pumped the AGC.  Stations could easily be heard between dits at 26 wpm.  That speed never varied except for my final contact with a slow speed guy.  On 40 I got smarter.  To eliminate being zero beat calling a station the TX Clarifier was set to +60 to 70 Hz.  That significantly increased the response rate.  On 40 and 80 I also reduced the BW to 500.  I know that the wide bandwidth will shock some of you, but I like being able to hear around the working frequency and find that the best filter lies between the two ears.  For a while both RXs were used.  One set at 500 Hz and the other at 150Hz.  That worked fine and some may like this.  Since the two RXs are not locked and that the time through the various filters are different, phasing effects are present.  That said, it was fun to use and signals were easily peaked while still retaining the ability to hear the surrounding area.  With the single RX running, using the APF brought the weaker stations to the front and eliminated the close-in strong guys.  That was used on less than 10 contacts, but was very effective.  The APF was set to wide.  I did not try the Contour in the peak mode in place of the APF.  If it's in the IF, that would make it even better.

In short, it was a fun time and the radio proved to be a winner.

I use 2Tone with N1MM, you can change baud rates in 2Tone settings.

I see no menu setting to change the baudrate from  45 tot 75.

For to decode 75 rate you have to use an external program , such as mmtty .  In that program you can setup rates.

Re: RTTY Baud rate

I used an external program in the end, but wondered if there was anyway to change the 101 decode as I couldn't  see anything on the rig or in the manual.


Re: FTdx-101MP Impressions

Lou W7HV
 

Yep. I'm not disagreeing, just suggesting a few things I found that work for me in helping ameliorate some of the shortcomings you mentioned.  You might consider joining the FTDX101 contesting group here:

Re: FTdx-101MP Impressions

Scott Ellington
 

I'm not sure why bandwidth would affect AGC operation. My issue is that I want the AGC response very flat, so I can hear the weak signals without punishing my ears on the strong ones. Yes, it makes it harder to distinguish the stronger ones in a pileup, so I have to ride the RF gain, but if it reduces hearing damage, it's a price I'm willing to pay. The option to set the AGC slope would accommodate various preferences.

I find even the slowest tuning rate for the MPVD is still way too fast for the rx clarifier. That slowest tuning rate is still 1.125 kHz per revolution. I'd prefer something more like 600. Part of the problem is that the ring is harder to manipulate than a small knob. For example, the small knob on the K3 goes about 500 Hz in one revolution, but it's very easy to control within 10 Hz, yet it's also easy to turn it half a revolution or so. An, no, I don't want to assign the MULTI knob to the clarifier; I need that for power output control.

I overlooked the BAND STACK, so that one is operator error, and I'll take it off the list.

I do have the latest firmware. To their credit, Yaesu did eliminate the faster rise time options, which only lead to key clicks.

Some of these limitations, like the fan cycling, the FTdx-101MP shares with the FT-1000D it replaced. Thankfully, key clicks is not one of them.

You can change the shift frequency for FSK from operator RTTY but you will need to use an external decoding program.
Something that I never tried,,

Re: FTdx-101MP Impressions

Lou W7HV
 

Yep. I'm essentially CW only and I've accumulated a list with 28 entries.

3. AGC.  I find it works better the narrower the WIDTH.  Of course you may not want a narrower WIDTH.

4. Agree. In addition to FUNC/OPERATION SETTINGS/TUNING, DIAL STEP equal 5Hz  you can set  MAIN STEPS and MPVD STEPS per rev to 250.  That provides the slowest tuning rate.

5. Yes. When you change bands, the MODE (incl side band) goes to what was in the BAND STACK memory for that band. There are three BAND STACK MEMORies per band (for both MAIN and SUB), and each of the three can have different modes.  They remember what they last were.

I suggest checking that you're on the 202105 software rev and set CW WAVE SHAPE to 8msec.  In the recent FW releases, Yaesu did make changes in response to customer input, but only a small fraction of those requested. 


RTTY Baud rate

Alan
 

There's an RTTY contest on this weekend. The rules state the baud rate as being 75. Is there any way to make the 101 resolve that on its decode?


FTdx-101MP Impressions

Scott Ellington
 

I've only had the radio a week or so, but I'm disappointed in it in may respects. Now, I'm a CW contester, and I'm fussy, so many others will probably not mind what I see as shortcomings. On the other hand, a lot of these issues would concern any serious CW contester. There's no question that the basic performance of the radio, like receiver dynamic range and transmitter IMD, is excellent.

Here's my list:

1. Very loud relays in QSK with separate rx antenna (much quieter with common tx/rx antenna)
 
2. Lack of per band power setting memory
 
3. AGC allows too much audio variation, no setting (this is strictly a personal preference)
 
4. Clarifier with ring control far too sensitive, even with 5 Hz steps
 
5. Sideband changes when changing bands (?)
 
6. Panadapter lacks averaging mode option
 
7. Fan cycles rapidly in rx mode (better to run continuously at low speed)
 
8. No electret microphone bias setting (wiring required)
 
9. Roofing filters do not automatically switch when bandwidth is changed

10. Output power still overshoots about 25 percent at 30 W (latest firmware)

****************
All of these, except the microphone bias, could be fixed in firmware. And the microphone bias is no big deal, as a resistor and capacitor on the mike connector takes care of it. Some of the others, like the clacking relays, I can probably fix temporarily with minor hardware modifications.

It would be nice if Yaesu DID listen to it's customers, or even paid attention to what one of its competitors has done.

Buy the Kindle digital version. Cheaper and instant download. Has good info! If you can't use a tablet or Kindle because it is too technical, you might as well sell your new FTDX101 now and avoid the misery of not being able to set it up😂
