If the rig supports remote control, the cable should work as well. The circuit should work for others Yaesu rig use similar protocol, just replace the connector to an appropriate one. Tested it worked on both upload and download memory channel information.ĬHIRP and a simple USB programming cable formed a free programming platform for my Yaesu FT-90. The chip of the cable is PL-2308HX, not the expensive FTDI one. I modify a USB to TTL cord, to test it works for Yaesu FT-90. Such requirement similar to ICOM IC-7000 programming / CAT remote control cable. I study above circuit and the interface port (mic jack) of FT-90R, I found:įrom the manual of FT-90R, Pin 2 is Data pin, Pin 4 is Gnd.ġ/ the 9600 bps data pin should be a bi-directional pin for TX/RX data.
YAESU PROGRAMMING CABLE SCHEMATIC SERIAL
I tried make one and connect it to my notebook via an RS232 to USB adaptor, but it does not work.Īs most of modern computer no longer provides RS232 serial port. When searching programming information for the FT-90R, I just found an RS232 interface circuit for this purpose. It is good, but it seldom to describe the programming cable schematic. With help from the open source community, a free programming software CHIRP was developed.
The most popular 3rd party vender is RT systems, The software with programming cable costs US$ 49. However, the program is not included, it needs extra costs. If it can be handled buy a computer program, it is better.Īlmost all Yaesu series rig can be programmed the channels via computer.
Manual input the channels is fine but not efficient. When got a new rig, the first thing faced is memory channel programming. I bought a 2nd hand but in very good condition on 2 years before at eBay. Yes, it is an old model, but it still available on eBay, as well as in Yahoo Japan bid market. The Yaesu FT-90R is compact but output max 50W, V/UHF mobile transceiver. It should work with other Yaesu handheld or mobile rig, which use similar protocol, such as FT-2600M, FT50, VX1R and VX5R.
YAESU PROGRAMMING CABLE SCHEMATIC HOW TO
This article describes how to make a USB programming cable for Yaesu FT-90R, which I did not find any information in Web.
