My radio was working fine up until recently. My transmit is fine but the audio on my receive is very low and the meter does not move at all in the receive mode. We've had some lightning storms recently. Don't know if that could have damaged the radio? I hooked another radio up to the antenna and...

I wired up one of my D104 mics to my Icom-718 and I was surprised to see that it works WITHOUT a battery! How can that be? Also it performs well on SSB but on AM I can hear a squeal coming from inside the radio when keyed even if the mic element is removed from the mic base. I hooked a battery...

Does anyone know if or how one would connect an Icom 718 radio to a Yaesu FL 2100B amp?

Hey Guys, I want to build a dipole antenna for 10 - 20 meters that I'll be using with a tuner. Out of these 2 options which do you think would work best? Using 1/2" metal conduit and making a 30ft vertical (15ft each side) or running wire horizontally through my hedges that are 10ft above...

Hey Fellas, Does anyone have any info on this amp. I do not have any paperwork on it. It uses what looks like two 30KD6 tubes and they both light. The relays do not however energize when an rf signal is present. The relays are good. I checked all the diodes, transistors and caps and they seem...

I have good power on all bands except 160 meters. On 160 I have about 2 watts output? I have tried adjusting TC-28 & TC-10 and it did not change a thing. Any ideas what could be wrong? Thanks...

Could someone please explain how to adjust the bandpass filter on this rig. My receive & trans is good on one side of the band but poor on the other. Thanks...

Are there any techs here? I have this meter that reads both rms and pep. I have attached a schematic. In the rms mode the meter needle rest at the 0 mark as it should and works fine. When switching to the pep mode with no input signal present the needle rises and rest at the 5 watt point. When a...

Boy do I have a headache! I am not an expert tech but have built many kits & I know how to read and use an VOM. I am using the Yaesu manual and trying to get the rig working like it should. When starting at band 10D as per the manual I can tune and get 60rms and 120 pep output on ssb on my watt...

Hello, I have read threads that say when replacing the finals on these radios with usa type tubes, before neautralization to change cap 125 from 100pf to 10pf. Is this the cap when looking from the top of the radio down at the finals, runs between the variable cap to the top of the coil located...

Hey Fellas, If building a vertical dipole supported by a METAL pole, couldn't you use the pole as part of the over-all length of the antenna? I'm looking at building a center feed antenna out of pvc and old cb antennas...thanks.

Hello Guys, OK, Years back I was in to cb radio and have an Antron 99 antenna. A ham co-worker convinced me to get my ham and I've had my license for some years and have used it every now and then on 2 meters. I got hold of an Yaesu 101E and have it hooked up to the Antron 99 antenna that I...

Hey Guys, I recently hooked up a Yaesu 101e and I'm trying to use it with a D104 TUG8 base mic. The mic works fine on my RCI but on the Yaesu the audio drive is very low on ssb and I even changed the r2 resister on the audio board to a 4.7m value as advised on one of the forums. I wired a cheap...

I have a low pulsating hum coming from the speaker when the volume control is turned completely down. As you slowly turn the volume control up the hum becomes lower and lower until I reach the 2 o'clock position and then the hum is gone. Would appreciate any help!
