Re: Maggiore 220 Receivers
I'll second (or third that)... I just put another on the air. The only thing I don't like about most of these type receivers is how they offer up the local speaker audio as the input to the repeater controller. Many of these receivers simply dump audio to a resistive load and you get the added (small but still un-needed) distortion of the additional LM-380 audio power amp (which can be almost 8% at modest volume levels), which you really don't want or need in the repeater receiver recovered audio path. Some Hamtronics' layouts use the method of taking audio (across a resistor) after the af power amplifier IC. Here's where the flames start. Actually, the Spectrum Brand of Receivers have a really well done buffered low level audio section to obtain the recovered audio without the audio power amp distortion. I don't want to add a Micor Slow-Fast circuit, all I want is a clean working fast-close squelch circuit built into the original receiver circuit, which provides full bandwidth buffered , gated and de-emph audio. Spectrum at least does this one thing very well (although their customer service is another story) Hamtronics and Maggiore could do a lot to improve this function in their receivers, even though the supplied circuits do work very well. After buying the receiver, it doesn't make a lot of sense to need to purchase or build an additional squelch board circuit to rid yourself of the crash noise. Otherwise the discriminator circuit in the Maggiore is really very nice and has great audio recovery - performance.
