I experienced very similar or the same problem with FT-840. When power is inceased over about 50 W, an AM on RF signal arises. Even when TCVR is supplied from accu and connected to dummy load. Period of interferencing signal is about 7.5 ms (130 Hz), so it cannot be hum from mains. I have not opened the PA block yet but i guess, it could be caused by damaged capacitor(s). Jiri

Hi, I understand that your router's signal is weak and other connections drop because of that. To resolve this issue, I would suggest you to change the wireless channel to 1(one). Because, the frequency on Channel 1 will not interfere with other RF frequencies. Thanks,
The FT-840 uses a die-cast RF power amp
with thermally switched fan to ensure full power output (up to 100
watts). The digitally synthesized local signals ensure clean, low-noise
transmitter output on all HF amateur band. There might be no AC line interference. it has strong Rf output. any AC line intersect does not affect its radio performance. Check and adjust RF power so to maintain proper output. some times more RF power generated at the output may cause interference. adjust Rf power..Even some unfiltered Noise getting the other end of the end may calso cause interference. Check for any Ripple voltages present at the output. Contact authorised service station for further Rectification. thank you shanth
No, a tranceiver cannot be assigned an IP address. It just converts the signal between two types of lines (fiber, copper, etc.). This is mainly used for connecting together networking equipments such as switches or routers.
Depending on the type of interface you plotter have, you may need a device called a Print Server. This device has an IP address and allows a conventional printer signal to travel through an IP network. If your plotter is designed to be connected using a LPT (Parallel) cable, like old printers, you may look for the D-Link DP-301P+ or DP-300U.
