[hpsdr] Hermes Project Badly Handled

[Terry Fox]

Terry (no callsign):

Please sign your messages with your callsign as well.  My name is also Terry (WB4JFI), but I have no such complaints or concerns about Hermes, or any other openHPSDR projects.  I don’t want others to be confused and think that I might have sent the message below.

I am slowly collecting parts to build a Hermes, and have seen a few messages about discrepencies(sp), but I am not alarmed or concerned.  This is a leading-edge project that has been designed and made available by amateurs for amateurs.  You can expect a few minor variations in a first-release design this complicated and handled internationally.

The main parties are working to sort any issues out, which is a huge advantage of the openHPSDR community.  Many Hermes boards are being used already, so the answers/corrections are known to someone.

I have built many other bare boards and kits, and first-generation documentation often takes a back seat to getting the boards and hardware out there.  Errata is common.  Look at the excellent N2ADR-based DDC/DUC board from Germany for example.  It is similar to the Hermes, and several parts are different between the schematic and the parts list.  Some parts are difficult to obtain in the U.S. as well.  But, I did manage to find the correct information, and now have all the parts to complete my board.  The early Softrocks also had some variations between pasts lists and supplied parts, especially as Tony was improving the designs.

Relax and enjoy the ride!  Remember, it’s a hobby.

Thank you & 73,
Terry, WB4JFI

Greetings,

I received Hermes - Bare PCB from TAPR a month back - looks Good. 

This is a Extremely high cost project - I really feel this has been badly 
handled by the person who have done the final board design.

There are several mistakes/disparity in the Schematics, BOM, Bare PCB Received 
and the Hermes photo. I am preparing a complete documentation about the 
disparity at a cost.

Which one to take into account is doubtful. None of the above matches with 
each other. Like there are few components which is there in the Hermes component loaded Board presented in the site, those components are also present in the Bare pcb but unfortunately, there is no information in the BOM - bit crazy. This shouldn't have never happened if Schematics could have considered the base-point or reference point. This kind of release will jeopardize the tempo of all user in HPSDR group who would like to build  his own device a bit discouraging factor.

What I understand Kjell, Kevin, Phil are the right persons who can respond to this.

73's
Terry
