[hpsdr] Orion_v3.7 firmware download

[Joe Martin]

All, 

Orion_v3.7 firmware package download is available at 

http://k5so.com/HPSDR_downloads.html

This version of Orion firmware adds an additional CW keying option by using digital input IO4 on Orion; pin 9 on J16 header and pin 9 on the rear panel accessory jack on ANAN-200D, to allow CW straight keying when in iambic CW mode.  This change permits the use of AUTO TUNE feature of some external PAs and/or straight key use simultaneously with an iambic key paddle.  The input line is debounced, KEY is low (to ground), UNKEY is high via a pull up resistor on the Angelia board.  

The user should ensure that the max external voltage from the keying source should is no more than 3.3V DC when unkeyed; no external voltage is necessary.  

73, Joe K5SO
