Uses a low-noise feedback circuit for Preamp 1. Refer to 1.1 below.Įmploys new diodes and coils in the RF BPF to decrease strong-signal IMD. (5 assigned channels open on USA version band can be enabled on other versions with modification.)Īchieves IP3 > +30 dBm (14MHz band standard value). The IC-756PRO III will incorporate some IC-7800 technology:ĥ MHz (60m) band standard on all versions. The IC-756Pro III incorporated the following changes as compared to the IC-756Pro II: 1. Icom unveiled the new IC-756Pro III at Tokyo HamFair 2004, which took place on August 21 and 22, 2004. The IC-756Pro III received FCC certification on Septemunder FCC ID AFJ217800. See Dave, N9EWO's Radio Receiver Page (link below). Otherwise, if your rig is as mine, you won't get a decent audio level on your AM transmission.New product information from ICOM The IC-756PRO III Hot News! The IC-756Pro3 has been discontinued as of late January 2009. The ACC1 audio is better, yes, but not so noticeable.īy the way, if you transmit on AM, I suggest to increase R426 to at least 4.7kOkm (in order to get similar TX audio gains on AM and SSB) and to reduce R449 to 7.8KOhm or so (to get full 100% AM modulation depth without reaching the opamp positive output rail). I suggest you do it only if you're comfortable with this level of hacking.Īnyway, with the mod I described you'll get quite some bandwidth just using the front mic connector. I've changed a few components on my rig to get high-fidelity audio though ACC1 and this required to remove the whole board form the rig and change two or three SMD resistors and capacitors. On the MAIN UNIT board there is an opamp (IC503b) which works near saturation and also has some high-pass filtering on it. Just a tip on the ACC1 audio: The rig, as it is, will give you a low audio fidelity through this connector, as it is intended for digital-like signals only. Could someone provide me the info with the right capacitor to use, a pic or diagram of the XLR cable connector made would be appreciated.Īny info or help would be appreciated and gratefully received. 001uf capacitor to use and if you solder one capacitorįor every pin/shield. 001uf capacitors as suggested but not sure I've brought some Starquad Canare cable and XLR connectors as I'm wanting to I've got the DEQ2496 set up, thanks to all the info here and on the web butĬould someone please give me basic starting settings for the MIC2200 if I'm connecting the ibox audio out cable via the back of the Icom through the New set up will be to start with (hope config is right) Sounds good and get good reports but need/addicted to the TX/RX Bandwidth I've got an Icom 756(non pro) to mod to get the voodoo audio.
