It is kHz, NOT KHz. The international standard is that k stands for kilo and upper case K is reserved for Kelvin.So even though it seems inconsistant we have Hz, kHZ, MHz, GHz.
The damping occurs after each excitation of the tank circuit, which is many times within each dit or dah. In a rotary spark gap transmitter this would be determined by the number of contacts on the r
I find that having a large LCD display, whether monochrome or color, deters from any attraction I might have for a radio. A frequency readout (or two) and a few other indicators is sufficient. All th
The SB-200 needs to have a 150 (approximately +/- my memory loss) volt DC line pulled to ground to key it. Using a relay driven by some lower voltage transistion output from the transceiver is one wa
Replacing the S-meter lamp is easy. 1) Have a good #47 bulb ready. Very common easy to find. 2) Remove the top cover of the Omni, 4 phillips head screws 3) Change the lamp 4) Replace the cover It can
Hi Mark, While it is true that a good ground is important, you should be able to make the radio transmit into a test load without any RF feedback into your mic audio. I suspect that there is somethin
I do not know whether there is an "industry standard" for rating UPSs. It may be that every manufacturer has their own unique way of rating that cannot be compared directly with others. Sort of like
Not quite. When the AC power is restored, if it has been off for a while and the radios have been drawing current from the batteries, the charger has to supply a high charge current to the battery a
There is probably an IC inside that is blown, the number LM-753 comes to mind. Though I have not confirmed, and my memory is not as good as it used to be. In Astrons I have serviced it is an 8 pin DI
This makes no sense to me. I am not claiming it to be untrue, however I do not understand how or why it would be true. Can someone explain if and why the above is really the case? Ken N6KB
The use of amateur radio, be it HF, VHF or UHF is absolutely unnecessary until the other services are down in a disaster. I believe most of us operate radio because we find it to be fun. With intern
I suggest connecting a known working low level (mic level) audio source to either the microphone input or an auxiliary audio input and see whether you get anything. Use a scope, dmm, vtvm, or vom to
Hi Jim, I don't have an Orion, and probably will not for some time. I am very happy with my used Omni VI. Of course I would love to have a receiver that is even better than the Omni VI and it seems t
Right on Al. Ten-Tec's legendary QSK is not an incredible technological breakthrough. Nor does it require more expensive parts to implement. It is just plain and simple good design. There is no good
