The ICOM 706MKIIG may also satisfy many of these criteria if this is your preference.
YAESU FT857D RADIO PDF
Operating manual and download the pdf manual.I've used the Yaesu FT-847 for many years and was satisfied with it's operation so I went with the more compact and improved FT-857D. Band-selected interface (for external band selected decoder).Highly effective noise limiter and IF DSP filters.Ease of use and reasonable user interface.Controllable, low-level power 28 MHz IF for driving an external, 1.25 meter transverter (via ALC).Separate power output adjustment for each band.Adequate drive power for external amplifiers on 2 and 0.7 meters.Built-in 100 watt amplifier on 6 meters.My transceiver selection criteria consisted of:
YAESU FT857D RADIO FULL
This saves a lot of time when you need CW in a pinch! Also note the full band-selected encoded BCD that's available on the CAT/Linear/Tuner output jack when "Linear mode" is selected (menu # 020). The "CW auto mode" (menu # 022) allows the CW key to be enabled even when you're in SSB mode. I ran 6 meters with the internal 100W power output while using external 100W amplifiers on the 144 - 432 MHz bands. Of note are the DSP performance on both SSB and CW as well as the easy band and mode switching. It performed flawlessly! I really like this rig for running the 4, limited-rover bands (50 - 432 MHz) with an external DEMI transverter for 222 MHz. 2013 Update: I used my repaired Yaesu FT-857D during the VHF contest. Note that the 70 cm per-amp located within the external amplifier was also blown!Ĭlick here to read about my solution to this problem. The 100W outputs from 2, 1.25 and/or 0.7 meters may have entered the radio via the 6 meter antenna causing extensive component damage. Shipped to Burghardt on 5/26/11, stay tuned for the results!Īccording to Jim (at Burghardt) the radio had suffered a high power spike probably resulting from the close proximity of antennas while the yagi stack was "nested" (mast retracted). I'm sure that there are others out there: In the past I've used both the national Yaesu and local Burghardt repair shops. All power outputs were measured at 14 VDC with a Bird meter and 1:1 SWR dummy load. All of the operating menu (and service menu) settings are normal. ALC indicates modulation on SSB.Ĭhecking the other HF bands indicates that they are also running at reduced power however both the VHF (144 MHz) and UHF (432 MHz) power outputs are within specifications. The AM maximum power is 12 watts (3 watts "QRP"). Grounding the "QRP" wire in the power cable reduces the CW or FM power output to 12 watts maximum. 22 watts (100 watts normal) and peaks with an RF Power Setting of 40 (menu #75) using CW or FM modes. 2011) the maximum power output on 6 meters dropped to approx. Sooner or later Murphy's going to get you!Īfter using this rig for one contest (Jan.
