Re: [Drakelist] What is he best way to test the N-4B noise blanker?

I've had light dimmers provide a good bunch of gunk. I forget if I was "testing" NB or DSP units with the one we had. BTW not all light dimmers are bad news. When I changed the one I reference above with a new 3-way dimmer switch, all the noise went away. Package said it had a noise filter i

Lee, Wire up a relay to act like a buzzer. That should generate some good ignition-like sparking at the contacts. Ken, WA2LBI On Sun, Feb 6, 2011 at 02:00, wrote: > Gang, > I need to test the noise blanker in my R-4CIs there an easy way to test > it? > No ignition noise here, no electric

If you "LOVE the mellow sound" you probably won't like the DSP audio filters. I have three of them, two Clear Speech Base Noise Filters on my TR7s and the Clear Speech speaker in my old Ford Explorer (because it was cheaper than a new quiet fuel pump or new car). I have been using them for abou

Re: [Drakelist] What is he best way to test the N-4B noise blanker?

Lee - Easiest is to connect a piece of wire to the antenna jack, then drag the other end along a grounded surface. A file is great if you have one, but just scratching along a piece of metal works. Switch the blanker on and off in SLOW AVC and you'll the see the average. Then on FAST AVC y

Depending upon what you want it to remove. For background noise removal, I use this one: http://bhi-ltd.com/index.php/products/noise-cancellation-products/item/noise-cancelling-pcb-modules-low-level/nedsp1061-pcb.html It can be used in the Rx audio line or the microphone audio to remove backgrou

Re: [Drakelist] R-4 serials

basically, yes. Take a look at I'm not sure if the "plain" r-4's are included in the series below the R-4A no.s. Donnie Garrett had a good listing of the s/n's for the R-4A's, but I don't know where it might be available now, he dropped out

Re: [Drakelist] R-4 serials

Yes, the R-4 series all are the same serial number string. The R-4 started at 100 (I believe, I've never seen one below that). The first schematic is labeled '0001'. The R-4A started at 2000 with the 13 tube version. The R-4A continued at 4054 with the 11 tube version. The R-4B started at

Hi agn, I found it -- Donnie's list. It's just for the R-4A's, but he points out the differences between the 2 versions. I seem to remember, and Garey can probably comment better, that there were some more small changes made toward the end of the "late" version, such that the very late one

So, based on Garey's serial number figures there were the following approximate number of each model built: R-4: 1,900 (or fewer) R-4A (13-tube): 2,053 R-4A (11-tube): 2,946 (or fewer) TOTAL R-4A: ~4,999 R-4B: 9,151 R-4C: ~13,849 (possibly a few more) T-4X: 3,749 T-4XB: 6

OK, It seems like Garey's suggestion is the easiest and it workstake a jumper lead, hook it to the antenna jack. drag it across a large file slowly...it generates nice ignition like noise. The NB does reduce it quite a bit. 73, Lee -Original Message- From: Richard Knoppow <1oldle

Al - Yeah, Donnie did a good job with that. We miss his 'special' parts, especially the little red ones! :-) I just finished doing a CD for the A-Line, so have some stuff together. The 11 Tube R-4A started at s/n 4054. The last version started at s/n 5400, and went through to close to 7000
