5、of the program. ? ? It is important to underline the “philosophy” behind the program. The main scope was the implementation of a robust and reliable tool to manage the transceiver, without the physical presence close to it. A typical application could be the installation of the transceiver and a ded
6、icated PC in a room immediately under the roof, with the possibility to fully control it from a first-floor room. For this reason the program has been designed in order to make it as robust and reliable as possible: after have sent any command to the transceiver, the program typically asks the TS-44
7、0 in order to have confirmation about the real execution of the command just sent. Moreover a monitor window has been included, in order to keep an eye on strings coming from the transceiver and sent from the Personal Computer. There are no advanced tool for memory channel management. (e.g. the poss
8、ibility to keep stored on the HD a set of memory banks to be loaded onto the 100 memories bank in the TS-440). ? ? The ? program has been designed and implemented for amateur purposes only. It is distributed for free, with the inclusion of the source code. The author thanks in advance any people sug
9、gesting or proposing any fix or any improvement in general. It is understood that users will use this software at their own risk. The author cannot guarantee the correctness of the program and cannot be kept responsible for any kind of problem or loss or any kind of damages to users devices. ? ? The
10、 communication between Personal Computer and TS-440 needs: The installation of a Kenwood kit named IC-10 (two integrated circuits ? and ?) needed to enable the serial data transmission through the ? port on the rear panel of the TS-440. It is possible to find those ICs on the market without buying t
11、he IC-10 kit, and install them following directions included in the User Guide of the Kenwood TS-440 transceiver. The use of a RS232-TTL converter to be installed between the serial COM of the Personal Computer and the serial ACC1 on the TS-440. Such device translates RS232 logical levels used by th
12、e serial port of the personal Computer in TTL logical levels, understood by the ACC port and vice versa. Kenwood puts on the market a product called ?, however it is possible to find a scheme to home-made such device using, for instance, a MAX232 or a couple of MC1488/MC1489. Please note that it is
13、suggested to use opto-electronic devices ? ? 4? for the translation, in order to physically separate the PC from the RTX, with the aim of avoiding problems of RF feedbacks. ? ?

The sample above (figure 5) shows: On the TS-440, the main VFO is VFO B. The transceivers display indicates 14.201.14 MHz); On the TS-440, the SUB
20、 VFO is VFO A (There are no indications on SUB VFO frequency on the TS-440); Pushing software button “UP” (or “DN”), the main VFO frequency will be incremented (or decremented) of 100Hz; ? ? 9? ? ? ?:?!?54?5? The ?!?64?7 contains a set of option buttons to select the desired mode. Please note that t
21、his frame may be affected by the use of other buttons/commands of the program. For instance, switching from VFO A to VFO B (please see A/B button in section 2.2.3) shall change the current mode if VFO B (the new main VFO) has a different mode from VFO A. ? ? ?!? ?;?!?54?!?5? The ?!?64?!?7 contains:

The panel is writing disabled; Two ?$2+? to increment (UP) or decrement (DN) the memory channel; A ?!?1?with a 00-99 list to have direct access to
23、 the desired channel memory, avoiding the multiple use of UP/DN buttons. When the user asks for an empty memory (by means of the DN/UP keys or the Combo box tool) a warning windows is proposed. Empty memories cannot be accessed. If the program is launched while the TS-440 is set in Memory Mode and t
24、he current memory channel is empty, the relevant memory frequency panel is set to 0,00. The memory channel panel remains empty. In the sample pictures above (figure 3 and figure 7) the TS-440 is set on VFO mode. For this reason the Memory panel is disabled. However the current channel memory (23) an

In this picture, highlighted commands, beginning from below (older commands) to above (newer commands), are briefly explained below: ?
28、 ? 12? 1. The PC asks the TS-440 sending the “IF” (Information)1 command. The TS-440 answers back with a complex string with a lot of information, including the main VFO frequency in Hz (00014201140), the RIT frequency in Hz (+0940) and several other info; 2. The PC asks the TS-440 sending the “MR”
29、(Memory Read) command attaching several parameters including the channel memori ID (23). The TS-440 answers back with a string containing the channel 23 frequency in Hz (00027255000), the current channel mode (5 stands for AM) and other info; 3. The PC asks the TS-440 sending the “FA” (VFO A) comman
30、d. In this case the VFO A is set as SUB. The TS-440 answers back with a string containing the VFO A frequency in Hz (00007200000); Please refer to the Kenwood IC-10 Instruction Manual to have a deep understanding of the proprietary serial communication protocol (commands/parameters). ?-?!? ?,?
