[Yaesu] RE:FT1000MP remote project

[Richard Harel]

     On the subject of  remotely operating the FT-1000MP with an FL-7000 
     amp. I thought I would add some comments on the subject for what it's 
     worth.
     
     I remote control my FT-990 + FL7000 using an AEA HamLink unit. I have
     a very good control of the xcvr, however not total. The remote station 
     is located about 20 km's from where I live but since it's a telephone 
     link, it really doesn't matter how far away I am. The big advantage of 
     AEA's HamLink is that all I need is one tel. line at the remote site. 
     HamLink uses the '990's CAT port. A #93# command interigates the CAT 
     port and the HamLink let's me know what freq. and mode I'm on. 
     Another advantage is price. I purchased my HamLink for $230
     - now that AEA is bankrupt, you could probably pick it up for less.
     I added an A-B box to one of the digital outputs on HamLink that 
     allows me to switch between a HF xcvr (default) and a VHF xcvr - so I 
     can also use local repeaters over the phone line. The HamLink has 7 
     digital outputs. D/O 1 goes high when you enter the correct 4 digit 
     code upon connecting. (This I use to switch on the AC power strip). 
     Another D/O goes high for 100ms (This wired to toggle up memories on 
     the VHF xcvr) and the other 5 are standard on-off digital outputs. 
     (These can be used  to turn a rotator, to turn on/off a DSP filter 
     etc.).
     The disadvantages of HamLink is that you can't actually 'see' the 
     radio. The freq. changes are in 10 hz, 100hz, 1khz, or 5khz steps. 
     Yes, you can scan from a lower limit to a higher limit if your radio 
     supports that kind of scan. Unfortunately, the FT-990 does not. QST 
     ran an article early this year about someone who used HamLink with an 
     ICOM 781 in the 'generic' radio mode.
     This means that the HamLink is setup not to communicate with the 
     radio's CAT port and only controls the PTT and passes audio. The 7 
     digital outputs also work in this mode. He then used a 2nd telephone 
     lines to control the radio from his PC at home using a remote 
     accessing program called "PC-ANYWHERE".
     What was very nice about his set-up was that he has a graphic display 
     of the '781 on his PC at home, complete with spectrum display that the 
     '781 has built-in. Of course the disadvantage here is that he needs 2 
     lines, 2 computers and it's much more expensive. My set-up doesn't 
     need any PC and I often call into it with a Cellular telephone and 
     work DX - it's very neat !
     Several people here use HamLink units and we can conference call 
     several stations together in different parts of the country to give 
     space diversity reception. 
     Good luck with your project and let me know if you have any questions.
