7-Mar-19 The EPROM images in this archive are for the Harris RF-350K HF Transceiver, aka the RT-1446 or URC-81, version 601c (the next-to-last). To use them, you'll need a set of 27C128-class EPROMs. The files themselves are all in Absolute Binary (Data I/O #16) format. File checksums are as follows. u16-601c.bin: 0xF7BB U17-601c.bin: 0x93F8 U18-601c.bin: 0x6F28 I'd like to thank the source for these files: Ken Fowler, KO6NO, of the East Bay Amateur Radio Club (ko6no.com).
