Rating: 5/5 Jan 28, 2009 08:05 Don't pass this one up Time owned: 0 to 3 months Yeasu FT-757GX review – I got this radio a while ago and so far it has lived up to my expectations. Good power with very good reports on the audio.

I added a JCD-201M digital compression mic to the unit, with very good results. The combination of the compression from the mic and the audio processor of the radio the unit really punches the audio out without crunch, over modulation etc. Just very loud and crystal clear audio with a very good dynamic tone. Let me side step a little, I got my first Ham ticket in 1974 (expired), then after many years got my ticket again. I have owned many, many radio over the years. I currently own about 28 of various makes models etc. Does this make me an expert – NOPE.

Transceiver by connecting with 'D' series microphone interconnecting cables. GENERAL USER'S MANUAL. 8 Battery Compartment Cover. I added a JCD-201M digital compression mic to the unit, with very good results. The manual says to set your radio for 25 watts to get full power but the facts are.

But I have a lot of experience with receive and transmit. Point being, I am pretty keen on receive and transmit features and have made mods/changes with some radios to improve these features. About the receive. Some complain about the radio being noisy. Yes, it is but that is because it is sensitive. I have another radio that I did some work on the receive and basically that radio will hear a mouse burp in China and the FT-757 with the RF-AMP on will receive just as well with no more and no less noise.

A couple things come to mind with respect with noise. One is a noisy antenna and/or RF on the feedline. I have two antennas for 10 meters and one is more noisy than the other. A simple choke by coiling the feedline 4 to 8 turns of a diameter about 6 inches can help.

The second thing is misadjusted controls on the radio. Let me take this time and explain a wonderful feature that the FT-757 has. The RF gain is tied into the squelch circuitry and it has a threshold. Let me explain how it works. If you turn the RF gain to a point that the needle is on S-5 (for example), an incoming singnal of S-5 or more is totally unaffected and you receive the full strength of the signal, any signal below S-5 will be cut back as a normal RF gain would do.

Unlike the squelch that blanks below the threshold you can still hear the stations, but at a reduced level. GREAT feature!!!! So you can set your RF gain to the floor of your noise and the stations over the noise level will be unaffected and you can still hear stations under your noise floor but with reduced signal (but a lot less noise). In fact you can pull stations out and have a clear copy with no noise.

This feature alone is a great one but used with the width and shift really makes this radio pull out stations and eliminate noise and adjacent QRM. Some radios offer a width control only, some offer a shift control only, some offer neither and some offer both. The FT-757 has both.

Learning how to use the RF gain, width and shift features makes this radio a joy to pull out those hard stations with no or little noise. It also has an adjustable (NB) noise blanker – another great feature, and it also adjust the AGC (automatic gain control), by adjusting the time constant of the AGC circuit. It also is used to set the blanking threshold and blanking pulse width. Another great feature!!! Where as other radios offer only a preset noise blanker.
