2017年7月6日 · The FT-891 has NO internal tuner, and also doesn't give you much choice for an automatic tuner (yet). This is something to consider, given that the FT-450D does offer a basic antenna matching (tuner) device. The FT-891 is a newer rig, and it will likely take time for companies such as LDG to come out with a dedicated 3rd-party tuner.

2018年7月2日 · The recent release of the warmed-over FT-817 is evidence of that. Plus, if you look at where the FT-891 sits in the Yaesu line-up you realize that an improved version with more features is a threat to both the FT-857 and to the FT-991A. Before Yaesu can get serious about upgrading the FT-891 platform they first need to kill off the FT-857.

2018年5月10日 · Many of you have asked for a Yaesu FT-891 tutorial for the digital mode settings with software such as WSJT-X. In this video we go through setting up the Yaesu FT-891 digi mode settings, configuring the audio interface to work with the 891, and configuring the rigs CAT Control settings to work seamlessly with WSJT-X. My Configuration in the video

2020年12月13日 · I was torn between the FT-891 or the Icom 7300 to serve as a base and portable rig. With a wife and family to support, I couldn't justify buying both rigs, so after watching several Youtube videos and reading different reviews claiming the FT-891 was about the best radio under $1000, and almost as good if not better audio quality as the 7300, I ...

2017年7月6日 · The FT-891 review quotes -116 dBc/Hz as the measured phase noise at 10 kHz offset. -116 + 140 = 24 dB or a 4 S-unit increase. Therefore, if you are transmitting and your spectral neighbor is 10 kHz away and within 1 mile of you, he/she will see a 4 S-unit increase in noise every time you key up.

2017年2月23日 · If you are thinking of adding a new radio to your shack or mobile check out this video on the new Yaesu FT-891! It is my opinion that you can't go wrong with the FT-891. I found it easy to set up, has great sound. Yaesu has even enlarged the display from what was on the FT-857D! The FT-891 is replacing my FT-857D in my mobile.

2017年7月8日 · Yaesu FT-891: $630 Alinco DX-SR9T: $566 Alinco DX-SR8T: $469 Of those models, the FT-891 has better DSP than all of them. Having owned the KX2, which I sold for the FT-891, I can say that I am very happy, so far. More testing in the field is required.

2017年7月6日 · Some of the 891's lab-measured values were worse than for the 950 (e.g, 2k blocking gain compression on 80m). 2k RM dynamic range was the same. 2k RM dynamic range was the same. That's not really a substantial improvement in receiver performance.

2018年5月10日 · Im wondering why cat control won't put the radio on Upper sideband when you switch to 40 meters or lower? I dont like using data mode on the 891 it sounds very narrow and doesnt work well. This radio makes no sense. Any other radio will change from lsb to usb when wsjt-x tells it to. Maybe there's a way? This radio has some pretty awful menu ...

2018年3月13日 · There is no VHF or UHF in the IC-7300, so what does all this mean.vi used the FT-891 for over 6 hours running 15 watts, 15AH Lifepo4 battery and it still had charge left. The FT-891 is great for portable use.
