    Chuck, thanks for a great video. Question, is the chip for the 87 available on the market and is it a direct swap? TY

      @@jerseyjeeper1575 Thanks! Yrs, the U12 bandwidth upgrade for the WJ 8711A is sometimes available on eBay and other places. If you have the ‘A’ version of the 8711/HF1000 it is a direct replacement. It isn’t compatible with the ‘original’ versions of those radios though.

    Great comparison video! Could you please confirm the HF-1000 Misco speaker part number - EC5WP?

      @@bp7315 Thats correct. Other models may work (I know they will based on other HF1ks I’ve worked on), but the EC5WP has ‘big sound’!

      @KI4BZJ Update: The Misco EC5WP speaker makes a **HUGE** improvement for the “speaker” audio channel relative to what I had been using (way ancient Motorola mobile communication speaker/enclosure). Thanks again for mentioning/documenting this important upgrade improvement!

    So, the plain HF1000A is more appropiate for the DX weak signal ? I understand this, I am mainly interested in voice signals. Or it would be better a 8711A for my purposes? I cannot listen any significant difference in this video.

      @@papierecriture Yes, the DSP filters in the HF1000A have wider skirts which allow more signal in and make voice modes more intelligible. Listening to voice modes is less tiring and much richer than in the 8711A. If you are listening to voice modes in crowded bands then the wider skirts could be a liability since you’d have to narrow the filter width to isolate one signal from nearby ones. Of course digital modes are better/tighter using the 8711A. For DXing it would, as you say, depend on what your listening needs were.
