There are indeed used professional receivers out there. You will get an astonishing radio if it has a name on it like Watkins-Johnson or Harris (two names that have shown up in this thread), but just because they're less than they were new doesn't mean they're cheap. I spent about a day's salary on my WJ-8716. I contrast that with the stuff I had thirty years ago and that's dirt cheap :-). In constant dollars I spent way less on the WJ than on my HW-100 back then. That said, I have a lot more fun with simple one-mode ham-band-only (or a few-ham-bands or one-ham-band) receivers. The most fun ARE just a step or two removed from the most simple. While the filters on my HW-16 aren't nearly as tight as those on the WJ-8716, the receiver of my HW-16 feels MUCH more like a "window on a slice of the 40M CW band". Once you have some experience with whatever you end up buying, you'll have a standard for comparison, and will know what to look for. A decent older ham-band transceiver is a fine place to start. Lots of radios from the 80's on are also general-coverage receivers. My advice is to not only listen and use and look "upscale", but look and try out "downscale" too. Some steps down will be too far (for example, I really do not enjoy direct conversion receivers although I appreciate much of their simplicity) but some other will be "just right". Tim. |

Guys that was a great discussion... But I still have a question or two. Well actually a lot more than that but we can't answer them all. --- I know I'm not ready to build my own receiver, unless I went the micro R2 route (I'm going to build one some day). But that still doesn't solve my need for a ham band(s) receiver - to use as a receiver and as a necessary piece of test equipment. --- why not kill 2 birds with one stone? for about $200.00 u can get the The Electroluminescent Receiver Kit http://www.pan-tex.net/usr/r/receivers/ its a kit that is designed to be a teaching platform and the pads are large enough to allow for multiple remove this and try that type mods. $60.00 of that price is a digital read out. |

oups.com... You asked about software radios? (I abhor the term SDR) Buzzword city, ultra-trendy, but I'd be surprised if 1 ham in 100 really knew how they worked. Does 1 ham in 100 really know how an FM demodulator works anymore? |

In constant dollars I spent way less on the WJ than on my HW-100 back then. You got a bargain, and I'm envious. My RF-590 cost more than my car, though that's not saying much. :-) I made up for it with my 51J-4 (oops...sorry...it's a Collins!), which I got for hauling it away. That said, I have a lot more fun with simple one-mode ham-band-only (or a few-ham-bands or one-ham-band) receivers. The most fun ARE just a step or two removed from the most simple. While the filters on my HW-16 aren't nearly as tight as those on the WJ-8716, the receiver of my HW-16 feels MUCH more like a "window on a slice of the 40M CW band". The HW-16 is one of the great radios, and is an excellent example of how simple a radio can be, and how well it can work. I had one for a while, but it kept frying the QSK switching transistor. :-( There is an enormous amount of choice out there. If you (the original poster) come across anything that looks even remotely useful, grab it. Laura Halliday VE7LDH "That's a totally illegal, Grid: CN89mg madcap scheme. I like it!"

Sam, I have looked at this receiver a couple of times. The price is
quite attractive and I would get to build it to boot. I was just a little skeptical. Have any of you built one? Does it work well? It sure looks like a hoot to build and use. He also has a 'basic' one band receiver kit as well. Don't remember much about it.

It sure looks like a hoot to build and use. He also has a 'basic' one band receiver kit as well. Don't remember much about it. Well I thought it over for a long time as well..... Then I met David, WN5Y one night on our regular Sunday night Echolink QRP Conference. After a long discussion with him I decided to try one. How well does it work? I'll tell you when I finish it. g I am maybe 1/4 of the way through building it. Is it a fun build, absolutely! I put the ELR (Electro Luminescent Reciever) assembly on the back burner while I built the m3 digital LCRZ meter http://www.m3electronix.com/lcr.html I figured it would be a handy tool for what ever mod I might wish to try on the ELR unit. So I'm just now getting back to building it. After building that little LCRZ meter it was a real pleasure to get back to the ELR's large boards and discrete components. I will say that I have had the occasion to need to ask David a couple of questions along the way and he has always been extremely helpful. He is even open to questions not only about the actual assembly, but is also willing to bounce around queries about modification you might be considering to the unit. My reason for the choice of the ELR was...... I have a TS430S that I had to send off to get it fixed. Not only did I not have the equipment to fix it, I didn't have the knowledge. About $250.00, 2 months, and 2 trips back to the shop) a return trip for something that wasn't fixed the 1st time around. After all that, I decided I wanted to learn how to repair what ever rx and tx I bought/built in the future. So I figured if I built it, I just might learn enough along the way to be able to repair it. Since my favorite bands are 40m, 30m, and 17m the ELR was exactly what I wanted. I'm sure enjoying the build and if I don't like it's performance (which I doubt will be the case) It's designed with the wider pads so that I can play with it and try out this, that, or what ever mods I think could make it better. Ever tried that on a board with those tiny traces and smd components? I'm not that comfortable with the dead bug or manhattan styled building, maybe later after I begin to understand theory well enough to try something from scratch. And the huge plus that the guy who sells it, encourages me to correspond with him about any mods and he is happy and willing to help me out with them...... Can't beat it as far as I'm concerned. Sorry for rambling on, I'll just close with the comment "try it (I really think) you'll like it" God Bless, KA5OAI |

The only mechanical filters that I have seen problems with are the Japanese units that you find in the JRC receivers. There is some sort of foam that deteriorates over the years. I haven't seen a problem with Collins filters. I have an old Collins filter made for the R390 series receivers. It is a cylindrical filter with two pins at each end for connections. I can hear something rattling around inside this filter as I tilt it from side to side. Has something deteriorated inside this filter or is this normal? A later rectangular Collins filter does NOT make this noise. |

The issue Pete is talking about is that those Japanese filters were made with different materials, and they decay with time. Michael VE2BVW |

Michael VE2BVW My filter has never left the original Collins packing (heavy cotton lining in a large cardboard box) since I got it at a hamfest years ago (for a project that never happened). I remember the filter seemed ok when I bought it, and it was NEVER dropped (by me anyway). Years later when I found it while packing for a move I noticed it developed this sound when handled. |
