These are some of the pictures of the light HF manpack transceiver based on the Yaesu FT-857 that I took today because several people asked me to through the FT857 Yahoo group and directly through my blog. On the first picture you can see the details of the antenna mounts for HF and VHF-UHF made out of aluminum plate. You can also see the SG-211 automatic antenna tuner attached by straps. Finally, the homebrew NiMH battery I made out of 11 4000mAh rechargeable batteries that I bought at a well known German supermarket chain.
As you can see on the second picture, the total weight of the radio is 4350g. That is a great improvement over the ft-897 manpack, which weighs 8.5kg or so. The weight improvement comes from a lighter transceiver (almost 2kg lighter), lighter tuner and using just one battery instead of the two that the FT-897 can hold internally.

ReplyDelete73's y feliz cacharreo, Patxi EA2WJ.
Como contrantena uso un hilo tirado por el suelo. La foto de abajo muestra la tuerca de mariposa que uso para conectarlo al chasis.
