If I get the chance to do this, I will report back on how it went. This will not be as easy for the HF side of things, as one finals has quite a few bottom board side lands that would be cut or damaged.

I needed to move the filter caps (input and output) closer to the body of the transistor, but otherwise it worked perfectly. The most accurate production numbers I have are: 6 MilSpec1030C, 15 MilSpec1030CI a nd 1 Milspec1030E DSP. Icom 775dsp Serial Numbers Indiralohathil Na Azhagappan Songs Free Download Gothic 3 Questpaket 4. On the VHF/UHF side I was able to grind away enough board and fit the new final in place. The driver (old MRF1508, New MRF1518) is different on the new board, but is basically a newer design, with the same spec's. The HF transformers and componets are the same between the two boards. Performance criteria is actually almost exactly the same. The primary difference between the old final and new final, is the package. I had the unique oppurtunity to evaluate the old 706 MKIIG PA unit and the new one.

The Serial number change is OLD > 0xxxxx, Newer 15(or 16)xxxxx. The 706 MKIIG has had more cases of final failure than the 775, more MK2G's sold out there too, than the 775.īeware buying used MKIIG's. The 775(DSP) PA unit is also pre-designed to use the MRF140's, the MKIIG cannot. The 775(DSP) has had very few cases of Final failure. You can swap out PA units for about $500! This includes the finals (no drivers)(706MKIIG only) A bit spendy, but at least there is a fix. The PA in the MKIIG was changed in about 2004 to a newer (totally different RD70HV)( New/Old Finals pic) device. Unsolder 24c02 and change the serial number icom 1120134 to 1801201. I have tried to contact a few sources, and a couple of parts hunters. Icom Ic 7000 Serial Numbers Icom 775dsp Manual I rest my case. You can write your own review of the ICOM IC-775DSP. The measured reciprocal mixing noise 'numbers' for the IC-781 are 1 dB better. The finals (SR(F or K)J7044(MP) are no longer available. Icom Ic 7000 Serial Numbers Free Software Serial Numbers The Icom Net has since moved to 14.316 kHz. who used the J7044 MosFet for a final, have a terminal issue.

These two, probably others, and any manuf. Tx power is radically different on different bands, probably the detwector diodes on the filter unit.

This is used in all the 706 series radio's, and the symptom is the radio won't turn on, and you hear a "click" "click" (relay closing and opening)ĭead, no Rx/no Tx, check the 5v regulators on the PLL unit, there are 3 of them. If you get a DC surge, there is a 4.7 ohm surface mount resistor on the bottom side of the PA unit, that is a fuse resitor for the regulators on the PLL unit. The DSP unit can get oxidized connections, resulting in garbled SSB operation/Mode mishaps/and dead modes (while other modes work fine) simply unplug the flex cable, and plug it back in, carefully.
