Here is my LDG IT100- my latest purchase- is an auto ATU that connects to the Icom 706 that I use mobile. Its a compact unit- you can see my mobile phone on top to give an idea of its size.
It came with a connecting lead for the 706 (about 15cm long, I had to extend it to about 1.5 metres) and a short patch lead to go between rig and ATU.
Although the ATU instructions say that the unit can be used mobile there are no provisions for any sort of mounting bracket, I have managed to mount it in built in plastic tray that sits in the Volvo boot.
In a quiet shack you would notice this ATU as the relays clatter quite loudly, not a problem mobile of course particularly as its in the boot!
The quality of the unit seems OK, but is does seem similar to the sort of construction of MFJ equipment in other words not really up to the standard of the likes of Yaesu, Kenwood and Icom.
Hi Kevin, very interesting as I have a 706 Mk1 in the mobile, do you have any other antenna's and if so what can they tune with the atu ?ReplyDelete
Hi Kevin do keep us posted on how the unit does on Eham they are rated at 4.6 which is not to bad at all. I have the LDC antenna switches both the DTS-4 and 6 and they are working great. They were rated at Eham at around 4.4 and the 6 position at a 4.0.ReplyDelete
Hi Paul and MichaelReplyDelete
The ATU will tune the 20 metre whip on 40 metres and 17 metres, I haven't tried the other bands as yet but the indications are that it will deal with a wide range of mismatches.You have to remember that because it uses a system of locking relays each time you QSY you need to tune up again (just one button press on the 706). Retuning normally takes a second or so as the ATU has memories built in.
I will keep the blog updated with my experiences of the unit, so far I am pleased with it.
I have a couple of LDG tuners - both work very well and find they are more flexible and tolerant to wider impedance mis-matches than built - in ATU's.
