Howard (et. al.),
Well, it depends.? A lot of folks think that Drake switched from "free filters" to "optional cost filters" when going to the R4C.? Partially true, but the details need to be examined.? The R4B used LC filters for selectivity and, with very broad skirts, they sounded very good because of the soft edges of the LC circuits.? The R4C used optional crystal filters and thus had steeper skirts so it tended to make things sound "harsher" but, for raw performance under QRM conditions, outperformed the R4B.? So you have to decide between comfort and performance, comm vs SWL, etc. 73, Evan -----Original Message----- From: Howard Traxler <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Sent: Thu, 29 Nov 2007 8:48 pm Subject: [drakelist] R-4A vs R-4C "Howard Traxler" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Hi again all. Here's a question that will require, probably a subjective answer: For about 30 years, I used an R-4A and loved it. I now aquired an R-4C--without any of those plug-in filters. I don't like it much at all. So I got another R-4A and was hoping to tweak it up to be like the one I used to have. Question: Why did I not need those filters in the R-4A and will I like the R-4C more if I get the filters for it? Which receiver should I put my effort into? I like to work both SSB and CW. Thoughts anyone? Thank you much. 73, DE Howard, WA9RYF ----- Original Message ----- From: "Doug Smith" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, November 29, 2007 7:31 PM Subject: [drakelist] T-4XC output on 160 Meters fades... : : Doug Smith <[EMAIL PROTECTED]> made an utterance to the drakelist gang : ---------------------------------------------------------------------- : Here's an odd one.. : : I just flipped on the rig and tuned up on 160.
