Components bridged (labeled V334, A475, D104) with 1uF Tantalum capacitors Not shown is enlarged microphone port opening, and internal baffle removal.. LED accent lighting strip underneath the plastic platform provides lighting for the IC-7200 front panel buttons in low ambient light conditions.. Yaesu FT-857 mic gain set to 15 (of 100) after a VHF audio test with other local hams.. Home > HF projectsICOM IC-7200Vertical stack-up for portability and to reduce base station footprint:A 1/4' plastic sheet is bolted to the mobile mounting bracket providing a platform in which to attach the LDG IT-100 tuner, Elecraft W2 watt / SWR meter and sensor.. ]Another proposed Yaesu interface cable:PSK31 receive-only interface cable for Yaesu FT-857 / Lenovo X61 laptop:No isolation - beware of ground loops!. https://osupunal.shopinfo.jp/posts/14898088
Yaesu FT-857DMH-59A8J DTMF microphone modification (W1AEX) - for improved low-end frequency response:W1AEX original proposed modification (PDF) for improving low-end frequency response (reposted here with permission from W1AEX).. W1AEX recommends a setting of 20 PSK31 PC soundcard interface cable for Yaesu FT-857D / LDG YT-100 tuner:Yaesu FT-857D data to PC interface cable simple, non-isolated audio design: schematic (PDF), gEDA/gschem file (Linux) [This circuit seems to be noisy (birdie heard) when the FT-857D frequency is adjusted every second by gpredict software for satellite doppler shift tracking, but no switching noise is heard when changing frequency with fldigi software - laptop or grounding issue? Maybe a Yaesu CT-62 cable will work better. 3
