Hi Mike, On my Corsair II, anything below a 3.5 on the front panel (RF Gain) and the receiver is pretty much dead. I tried it with and without the AGC being turned on. Before digging to deep into the
Jack, Futurlec lists a medium speaker which is 66mm diameter (2.6 inches), 4 ohms, with a 1W power rating for $1.30. You can see the speaker at: <http://www.futurlec.com/Speakers.shtml> Jerry W5JH "b
Hi Folks, I have about 6-8 of the Motorola speakers. These have a diecast front panel painted a cream color with the Motorola name in red. The back cover is gray in color. I discovered these speakers
Curt, You might check with Glenn at DSMLabs.com. He does a lot of TenTec repairs and owns a lot of TenTec equipment. His phone number is on his web site. Jerry W5JH "building something without experi
The amplifier described below is also sometimes known as a "Norton Amp" since Dr. David Norton patented it in 1975. Because of the patents, it has not been used all that much. The amplifier is also k
Gary, I am happy you have found a solution! Jerry W5JH "building something without experimenting is just solder practice" For those with hearing impairments, the joy of using amateur radio is diminis
Hi Steve, I agree with you. I don't quite understand what is going on with the convoluted Bridge-Tee diplexer on the Corsair II. A properly designed Bridge-Tee diplexer with a Q of 1 would have L5, L
Hi Steve, Ah, this is funny. I was typing this email to inform you that I think the value of L5 should be 0.33 UHy when I received your email. I didn't measure L5, I just took a guess that it might b
Steve and Barry, After studying the schematic for a while, I think L1, L2, L3, L4, L7, L8 are all 100 uHy and not 100 mHy. First, 100 mHy inductors are huge devices and second that large of value is
Steve, I doubt if TenTec had very many proof readers in 1986. Usually the design engineer has to sign off on the drawn schematic and should have caught a lot of these errors. All I think we can do is
Steve, I hope you leave the pictures on the web site until I get around to building it. Jerry W5JH "building something without experimenting is just solder practice" I finally decided I needed to do
Richard, One of the things you can do is to mix more than one input to a single output. Let's say you to record some audio and play it back, a mixer would let you do that and allow you to adjust leve
Richard, I record through mine all the time. I also play back through it. My low cost "old" recorder does not have recording controls. Sorry you can't see the benefit of one. Maybe your wife is corre
For my TS-590S, I built everything inside of the 8 pin mic plug. I used two tantalum caps and two 1/8 watt resistors and removed the pins of the mic plug which were not used to allow a little extra r
Hi Mr Richards, I just send you two emails with 10 pictures of the headset adapter. Jerry W5JH "building something without experimenting is just solder practice" Cool, Jerry, I am not that handy as t
Hey Rick, I am glad I did not win that lottery! Jerry W5JH "building something without experimenting is just solder practice" Hi John, Yeh, I guess it's a crapshoot with these cheap headpones. I neve
Mouser.com will have them a lot cheaper! A 330pF ceramic cap at 6KV only costs 73 cents! Jerry W5JH "building something without experimenting is just solder practice" Bob and others On pg 43 of the l
It all depends on what you are using it for. The door knob is a ceramic cap. If the use is to parallel the loading cap, then the high voltage is not needed. A 1000-1500VDC disk ceramic would be more
Hi Curt, A year and a few months ago, I sold a new logic board for the Corsair II. This board was designed by Stave Hunt, G3TXQ. It included the logic to control the display board and it also had a n
Hi Steve and All, This is the way I see it. As long as we do not add liquid soap to the rain water, we should be OK. And, if we decide to wash our window line with liquid soap, we have to make sure w
