About this deal

I agree that the root cause of the difficulty is separating Sota stations in a pileup is unique to the way we advise our QRG. The callers tend to be nearly coherent and no matter what the dynamic range will we split them up. Roy G4SSH with a lot more experience of CW operating always called me a few 100Hz off frequence, sneeky but effective. That said I would like to try an FT891 in field conditions to see how it performs. The other alternative, as discussed, is the KX3, or similar, with a measured dynamic range of 107dB, I believe this has the best RX measurements for any portable rig.

I can also use the 7300 remotely from the armchair but prefer to use an actual radio but I can compare the DNR directly and the 891 beats the 7300 hands down and the ability to completely eliminate all the miles of electric fence noise I have around me is a big plus, the 7300 struggles to eliminate heavy electric fence noise, with the 891, it's completely gone.The 32 but high speed floating point DSP (max 3000 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently frustrating in the HF frequencies. Also the AUTO NOTHC (DNF) automatically eliminates the dominant beat tone. The CONTOUR and the APF are very effective receiver noise reduction tools in the HF bands operations. The YAESU original DSP QRM and noise reduction functions are provided. With this setup, we will use the computer sound card (or USB sound card) for the audio in and out of the computer, connected to the radio via the RTTY/DATA port. We will use the USB connection to the radio to initialize the PTT during transmit, and to let the software know what frequency the radio is on. Reports vary on the power consumption of the FT–891. It certainly isn’t as high as the 2.0A documented in the user guide. I don't find the menus very annoying, most of them are set and forget anyway so they don't bother me and once familiar with the menus you need it's just fine. It’s a needlessly complicated system, as I discovered recently while recording another Shortwave Radiogram broadcast. Even after testing the procedure previously for this article, the radio was determined to stay in LSB no matter what. Memory Programming

Out of this wide array of options, I’ve only explored Digital Noise Reduction and the Narrow IF filter so far, as they offer fairly immediate gains without too much configuration. Three programmable Front Panel Function Keys Support for ATAS (Active Tuning Antenna System) The FT-891 fully supports the ATAS-25 and ATAS-120A Active Tuning Antenna System (optional) allowing for plug and play field and mobile operation. Ultra compact design Measuring 6.1” x 2.0” x 8.6” (155 x 52 x 218 mm), The FT-891 is an innovative Multi-band, Multi-mode Mobile/Portable transceiver with an Ultra Compact and rugged case design. Optional FC-50 Antenna Tuner Unit The FC-50 is a microprocessor-controlled antenna tuner that is designed specifically for the FT-891. The FC-50 can be easily coupled with the FT-891 and includes all necessary interconnect cables for operation right out of the box. Specifications Specifications Hirst, Mark (2021-03-02). "Guest Post: Mark's review of the Yaesu FT-891 as shortwave broadcast receiver". The SWLing Post . Retrieved 2022-08-10. If anyone is looking for a really great sounding radio for SWL then if you can the 891 is well worth the extra money, look out for a 2nd hand one. The 891 is not very sensitive on Longwave but using the preamp it does help a lot. While this audio profile may not be to everyone’s taste, the extra sparkle yields voice audio that is clear and distinct. I find those low frequencies make the audio muddy and tiring to listen over long periods, so I’m quite happy with this.It has all been said already but I wanted to add my own review on this radio. Having owned an 857D and still owning a 897D, the 891 is a step-up in terms of quality of RX, display readability and even transmit audio. Measuring 6.1” x 2.0” x 8.6” (155 x 52 x 218 mm), The FT-891 is an innovative Multi-band, Multi-mode Mobile/Portable transceiver with an Ultra Compact and rugged case design. dB -60 dB SSB/CW 2.4 kHz or better 3.6 kHz or less CW-N 500 Hz or better 750 Hz or less AM 6 kHz or better 15 kHz or less An alternative and perhaps faster method is to press the M>V button. This brings up a multi-line listing of memories that can be scrolled through using the multi-function knob. Pressing the M>V button again copies the selected memory to the VFO and leaves you in VFO mode. This avoids the radio flipping across bands and the associated relay activity. Uncompromising Receiver Circuit Design Ensures Excellent Performance • Triple conversion with a 1st IF frequency of 69.450 MHz (SSB/CW/AM
