The MBA-RC is a single box that is a full function decoder and display unit for Morse code, Baudot (5-bit RTTY/Teletype) and ASCII (7 or 8 bit RTTY/Teletype/computer) data streams. It takes in audio from any HF, VHF or UHF radio, TTL, current loop or serial signals plus +12v (at about 1.2 to 1.5 amps) and outputs its own 32 character scrolling display or drives a printer.

The PK-232 was the flagship of AEA's product line, and THE unit that other companies tried to equal. Few products in the history of amateur radio have endured the test of time as well as the PK-232. Even fewer products in the digital age have survived more than one decade. The PK-232 was introduced in 1986. Offering all of the current digital modes - RTTY, AMTOR and CW - in one box made it an immediate success. The orders rolled in and AEA licensed the design to the Heath Company to produce the HK-232, a kit version of the PK-232. Over the next few years, several firmware upgrades added additional functionality and increased the reliability. In 1989, AEA introduced the "PakMail" upgrade, a mailbox daughterboard with battery-backed memory. Later in 1989, the mailbox daughterboard was integrated into the PK-232 main board to make the PK-232MBX. The new PK-232MBX had a number of other hardware changes, including changing the front panel LEDs from all red to a combination of red, yellow and green and adding a hole in the bottom of the housing to allow removal of the battery jumper without removing the housing. In 1993 AEA added Pactor and Gateway modes to the PK-232. The final AEA upgrade, GPS compatibility, came in 1995. AEA sold their last PK-232MBX units in early 1996, intending to replace the PK-232 with the new DSP-232. Unfortunately, AEA closed its doors in 1996. They sold the data products line to Timewave and the antenna products line to Tempo Research of Vista, CA. In late 1997, Timewave shipped the last of the remaining AEA units. In the fall of 1998, Timewave introduced the DSP upgrade for the PK-232MBX. This upgrade substantially improved performance resulted in the PK-232/DSP. In addition to its precision DSP filters, the PK-232/DSP featured lower power consumption, a reset switch and an overload LED. In 2001 the advent of the sound card modes, especially PSK-31, brought yet another upgrade to the PK-232. Timewave engineers created the PSK sound card interface board, a testament to the amazing flexibility of the original PK-232 design. In 2005 Timewave added the USB upgrade to support the new generation of PCs that lack a RS-232 serial port.

NOTE: EPROMs aren't forever. Given enough time they will all drop bits.
If anyone would like to read the EPROMs in their PK-series unit and email us the image files we will host them.
Then as folks have problems due to bit rot they can erase and reburn their EPROM chips and get their unit working again.
On the .hex and .bin files below you will want to right-click on them and "Save As" to your local hard drive.

These EPROM images are provided for you to replace the same version EPROM in your unit. There may be newer versions here than you have in your unit. These won't necessarily work in your unit, especially if they require changes to the hardware (extra or replacement chips).

DSP-2232:
The DSP-2232 followed the PK-232. It's basically a PK-900 with DSP and more and better modems. Here are EPROM images. Each file is 65,536 bytes and goes into a 27C512. This firmware is Version 7.0A dated 1993-12-01.

Anyone want to contribute some other EPROM images?

Here are some photos of the EPROM installation.
The picture pk232mbx-roms.jpg shows how the PROMs should be installed in the PK-232MBX. Note that each EPROM chip has a notch in the pin 1 end. Watch that you get them in the right direction, you will destroy the chip if it's installed in the socket backwards! And it's way too easy to fold a pin underneath. So look twice and BE CAREFUL.
The picture pk232-mem-expansion.jpg shows the memory expansion board that was available from AEA to upgrade a PK-232 to a PK-232MBX. The board provides additional ram and sockets for 2 larger eproms (ver70 software EPROMs shown installed).
