Icom 7000 and 7300 as I have both work down to 12V reliably. They get fussy at? around 11.8V.? ?That however is measured at the rear panel connector.? Long wires and fuse issues even at 13.8 can

I checked power supply connections. Good. I came across 2 patch cords that had gone south. One was new a year ago. The radio is working as it should. Thank you to all who replied. Now to play on hf.

Hi Most Icom radios will not operate on low voltage, i.e. 12.5V lead acid, always feed with 13.8V min. Yaesu and Elecraft will go down a bit. KR Andrew Sent: 03 February 2025 15:31 To:

The IC-7000 is VERY voltage sensitive.? I had the exact same problem.? The very nice and competent gentleman at the St. Joseph Icom Service Center set me straight.? The 7000 needs 13.6v.? Use a

James, Before you do anything, make sure the power supply can handle the transmit current of the rig. If it did it before, it’s probably fine. And definitely, take out the blade fuses from

Check the absorption of the power supply, check the contacts of the cable with the power supply and with the radio and finally check the fuses along the cable itself, they must have a solid electrical

I've owned my 7000 since new. Recently upon attempting to TX on hf the radio re-starts. Any ideas before I send it off? Tried different antennas same result. Haven't tried vhf or uhf.

I have done a little more troubleshooting around the LPF final filter section. I unplugged the cable from the main board to the PA. I set the freq to 14.2 MHz. I separated the output of L305

20% high does not sound too bad!! It is when they drop low and you lose 90% will be the issue. 73 Andrew ?Get BlueMail for Android ?

JD I think Andrew suggested that capacitors may be the issue. There are two large smt capacitors in the filter section after the PA section. I removed these and measured them. The result is as

Steve Great info. I will consider these measurements, especially the ALC section. Thanks Tommy [email protected]> wrote:

Thank you for this update, Pentti OH5KOA. This is great news!? ?It was a difficult repair in many ways, and you did very well to find the parts.

Tommy, This file in the Group's Files section shows RF levels at key points from the IF output to the Antenna output.? Typical ALC levels are also shown at the

Update, the coil cans I ordered have arrived and have also been installed. High-quality and functional parts, which I did wait a little while for. The radio now works great. I can recommend the

RL801 may not be making good contact. You can check the levels with your scope. I would use SSB and whistle in the Mike for tracing to keep the power dissipation low. [email protected]> wrote:
