The radio does receive properly without the amp. I will see about ordering a new relay for the amp. Thanks much

Hello. Can someone explain why my receive goes quiet after transmitting on my radio? If I click the microphone button on and off, then the receive comes back. I have an amplifier in line, maybe something is going out on the amp ?

Hello everyone. So I had to move 2 capacitors to read the uf and voltage to complete schematic with board # and values. c111 .1uf 16v and c93 .1uf 16v capacitors. I plugged the radio back in and turned unit on, the hum is gone. I will start the process of replacing each cap and checking...

Thanks. I'm checking them out. I appreciate it

Sorry connected

No problem with regular charging system. I contacted my radio straight to the battery and the voltage is 12.6 .the radio would perform better at 14.5 to 15 volts.

Hello everyone. Does anyone know if it's possible to up the voltage in a vehicle for a mobile radio? I know vehicles are considered 12 volt and amp hr depends on size of battery, but I would like to up the voltage similar to using a power supply. Maybe its possible to design something with...

Hello everyone. Is it possible to Calculate the DB gain of you're signal from an antenna, or how much gain an antenna is producing?

Thank you

Hello. I have a Delta PSM1000W. What is the process for calibrating this meter? How do I check and see the accuracy?

Thank you sir. I will try and let you know.

Any idea what size? The antenna specs say Thank you for the information. What capacitor would you recommend that I put back to make antenna work properly?

Okay. So I used mfj antenna analyzer today and the antenna was reading 80 ohms . I changed the horizontal angle of antenna a few degrees and rechecked. I ended up moving it about 1/4 " and now the analyzer is reading 50 ohms. It also changed the 1.35 swr down to 1.2. Now channels 1 & 40 are...

Do you know what I can put back on it ?

Hello. I have a k30 magnet mount antenna. The receive went away and swr went off the chart. I took the magnet off the bottom of the mount and the coax is burnt. It looks like it had a resistor or something Sauderd across the transmit conductor and shield. Does anyone know what this is or...

Ah , good idea. Thanks. I'm not sure where to post , but I have a k30 mag antenna. All the sudden the receive disappeared and swr went off the chart. I opened the magnet and it coax is burnt. It looks like they used a resistor or something between the transmit and shield. Does anyone have...

cool. Thanks. I ordered one. When it gets here I'll check it out

Okay . So how do I tune for resonance and reflect powerof modulation. Antenna analyzer and oscilloscope?

That's a good idea. I'll try that That's what I was trying to do. I appreciate it. I'll let you know what the outcome is. I also ordered a new Nano VNA analyzer. I drove the truck today and was able to hear clearly and speak to people all over the united States.
