[Premium-Rx] HRB SYSTEMS HRB-1390A

[Rich MC Clung]

Anyone on the list have one or any data on it.
I have one that I've had for several years sitting on the shelf.I finally got around to checking it out and it seems that the5K filter has a problem. The audio is down compared to the the other bandwidth positions.
I had a 2nd one in the wings but the owner passed away before we made the trade and all of his stuff was taken byto a relative who sent it all to a scrap dealer.
My plan was to rack mount side by side and use them to Beacon and BCB DX. 
I believe Nigel GM8PZR was looking for some information about 10 years ago. He also had mentioned have some command codes that might work with it.
