I have two Sonars. Both 23 channel models. One is an fs 23 the other is an fs 3023. Both work fine. The tubes haven't been checked but both radios transmit And Recive excellent. Both are nice cosmeticly with a few scuffs and scratches hear and there, nothing major. Both have amplified d 104's. The 3023 is nice and clean inside while the fs 23 is a bit dusty inside. All knobs turn nice and smoth. Squelch, rf gain, volume, clarifyer anl and meters work as Thay should on both radios. Both adjustments (meter and rf) on rear of the radios also work as should. Depending on what you have the Mic's may or may not be included. If your interested in swaping something it must work 100% as the Sonars do. Absolutely no issues. Cosmetic wear from use is ok. These Sonars are very nice. Great audio reports. Recive is excellent on both. Thay were unpacked and used for about 2 hours each over several occasions. I packed them back up. If you have something I'm interested in I will unpack them and send you photos. So what u got? Don't need cash but if you don't have something I'm interested in I will Concider a fair offer. P.s I was Concidering a near future purchase of galaxy a.m. ssb base station think it's a 2547. I don't recall if that's the proper model number but you know what I'm talking about. Thanks.
