The Noise Blanker function is about the best there is. The use of narrow selective filters will often make the pulse noise become a wider pulse. A wide filter is preferred. But considering tha
I trust you were aware the NB offered 2 different levels/width of blanking. Also if one used the 600 or 300 Hz filters the NB function was much less efficient. 73 Bob, K4TAX Sent from my Linux devi
Well I don't see that as being "the way it is". Yes the FCC has been operating with greatly reduced staff and available facilities. They aren't allowed in their building due to current COVID restr
Start first by using a 12 volt battery, like the one on your lawn or garden tractor. Connect your radio direct to the battery. Note the S meter reading for the given band and frequency. Then drop
Well, I believe you said it is your fence. If so, go look in the mirror and complain to the fellow until he does something about it. Or take the fence down and feed the deer. One fellow suggest an
Usually those counters have provisions to set the IF offset such that it reads correctly. Then one can calibrate it to the closest Hz or so. The true accuracy depends on the counter time base accurac
I just sold two for between $250 and $450 each. That in my opinion is a realistic value and not an in love with it price. Bob, K4TAX Sent from my iPhone
As a rule, it is worth more in parts than a working radio. Frankly, I wouldn't invest any time into repairs, even if it was given to me FOC. 73 Bob, K4TAX That sounds too hard for me. It is far from
Good morning Snowy. The wife and I have both received our 2nd COVID vaccine. We still take precautions when going out into public by always wearing a mask and using hand sanitizer as needed. As my
John: I've owned several of the Paragon radios. I really like the way they perform and the way they sound, both on RX and TX. However, I've found that they take an inordinate amount of time to mai

Well for those that are in the LP-PAN2 camp, they would suggest it be used. And for those that are in the SDR-Play camp, they would suggest it be used. I've used the SDR-Play/RSP-1a both from the I
The headphone jack is a 1/4 TS jack. So youll need to use mono headphones or use a 1/8 to mono 1/4 adapter for stereo headphones. (Hate those adapter things.). There are isolation resistors so should
Bob: I'd say 99% of the issues of this type are from a dirty control. It can be removed, it can be opened and cleaned and it can be re-assembled and installed into the radio. I have pictures of t
Oh the Contesting . com site won't allow pictures. Something about files being too big. And the ones I referenced are on the Tentec Eagle site on Groups.IO. 73 Bob, K4TAX The MULTI encoder is a segm
The typical power spec is +/-1 dB. That means anywhere from 80 to 125 watts is within spec. 10log(P1/P2) = DB Then add the +/-10% accuracy of the typical ham power meter and you have ???????? B
All of this smells of: (a) excessive grid current, (b) gassey tubes. GRID current is THE MOST IMPORTANT current to monitor on grounded grid triode amplifiers such as the Centurion, SB-220, TL-922 and
Your will need to put a DC amp meter in series with the 13.8 V red wire from the power distribution board going into the PA box. With the radio in USB mode, mike audio to minimum, key the transmitter
If you have installed Zoom on your ham/shack computer, be advised the default setup allows Zoom to override your manual settings for both transmit and receive audio levels. It substitutes gain value
Depends on the dummy load. Good quality loads stay very close to their R values when cold to hot. While others will usually migrate up in R value. The air cooled loads are more prone, from my exp
