REMOTE CONTROLThe Kenwood R-5000 receiver can be remote-controlled from a external device like apersonal computer. To do this, the receiver must first be modified and an external levelconverter must be used. Each of these can be bought from a dealer or directly from Kenwood. Ifyou are technically capable, you can do these yourself.Remote control of the R-5000 has a number of applications if you wish to do automaticlogging of stations or unattended recording of broadcasts. I find it most useful to mass-programthe 100 channels of the R-5000 depending on my listening interest at the time. I can load all themilitary HF aircraft frequencies in less than 30 seconds! I can then scan those frequencieslistening for Air Force One transporting the Big Guy around the world. Then if I want to monitorshortwave broadcasts, I can load all those frequencies quickly and just scroll through thechannels looking for the best frequency to catch latest Radio Japan program on learningJapanese. Using the frequency lists published by the monthly monitoring magazines and SWclubs, I can quickly adjust my receiver's channels to the latest frequencies. Some of the remotecontrol programs even have periodic lists available to those who purchased their programs.REMOTE CONTROL MODIFICATIONDealers offer the IC-10 modification kit for the R-5000 for anywhere from $30 to $50.The kit simply consists of two ICs: a 4040 CMOS binary counter (IC55) and an 8251A UART(IC54) that are installed into sockets on the control board. If bought from a mail order electronicparts store, these parts will cost less than $10 (see Appendix A). Figure 5 shows where the twochips are installed on the control board. Please exercise proper CMOS handling procedureswhen installing these parts! See Appendix C for CMOS handling procedures.12
