For example, if you use the 1.8 kHz filter, 1.9 kHz will be inaudible. phase of the modification I found that the band matrix is setup to use the 80m low pass filter up to 6.

But the IC-756 PRO filters are deliberately designed to reject adjacent interference on our crowded bands. Home> Archive for Category: Icom 756 pro ii. The filtering on the radio is pretty impressive and you can adjust the filter shapes in SSB & CW even on 2M! The radio uses the same 32-bit IF DSP as used in the IC-756 PRO-2 and overall, I really warmed to this radio right from the get-go. Digital filters have a flatter frequency response in band and then roll off more quickly.

It's one of those passive things that you have to manually set sweeping and the audio cuts out while it's doing so. It has a bandscope (of sorts) which was probably considered very good in its day, but it seems a bit old hat now that there are so many rigs with high resolution panadapters and waterfalls. Note 2: The tranmsmitter MUST be keyed from the ACC2 connector using pins 8 & 9 if using ACC2 pins 11 & 12 for audio input. Speaking of tuners, the radio has one built-in and it's good for up to 3:1 matches. Note 1: When using the ACC-2 input, the C131 capacitor must be changed to a 4.7uf for low frequency response to pass. C492 C493 Analogue TX filter bandwidth 470 pF 2.2 nF 4.7 kHz. This function allows 3 of these 51 types to be pre-set for. This filter shall not limit the TX audio bandwidth, so its bandwidth needs to be higher than the elliptic filter, so we can select, Increasing the SSB / AM audio RX & TX bandwidth on the ICOM IC-756 of 6. blocking by extremely strong adjacent signals out of the filter pass bands. There's connections for a linear, data, tetc, etc and one for an external tuner. (50Hz3.6kHz) of the digital IF filters used for IC-756PROII come in. The IC-756PROIII has two pre-amplifiers, which offer advantages in bad band.

The menu system is pretty intuitive and like I said, I've not had to pick up the owners manual yet.Īt the back, the radio provides two HF antenna connections and one for 2M (all of them being SO-239). Moving from band to band and mode to mode is very simple and so too is the tuning - be it fine or coarse. It's also quite annoying not having a readout for the power-setting you have to key-up to see the power on the bar-meter. And they're proportionally longer than they need to be which always gives me the feeling that they'll be under undue lateral load over the years.

The screen is big and bright - love it! There's lots of button, knobs and dials and they all have a great feel to them apart from the four tiny rotaries on the bottom left of the rig - they're just a bit too small for my liking.
