Question about Two-Way Radios
Recieve no transmit hr 2510
I know these are old posted questions but here are some new answers..... Simplest first! Make sure the TX button is not engaged, if it is then the radio will not work correctly.
Second would be a bad final or driver, this is a tough fix as these parts are tough to find, the parts are no longer made. A fix has been devised using MOSFETs but I have little details on this.
Third but not last is to do with age and environment, a glue was used to stabilize parts to the boards, wire and coils typically. This "glue" will break down over time and exposure to moisture and become conductive, shorting out parts and also corrosive, making copper wire and traces come apart.
Lastly, incorrect bracket knobs with screw threads too long can actually "crush" the PC board and break the PC copper traces.
Dropping the radio is not good, cracked boards and broken wires in hidden places.
Repairs can be made on all these but you need a tech that has experience to find these.....

Can be caused by many things. Usually the first thing to suspect is blown power output transistor/s. Was the radio transmitting into a properly matched load? ( ie. an antennea designed for the transmit frequency) and was the VSWR monitored?...pretty obvious stuff for Hams to know...
My 2510 started to have xmit problems that surfaced as audio/transmit signal quality problems...than soon progressed to no RF. I dont know if this rig is subject to occsillation problems...I have also heard that this problem is often causede by a capacitor goinng bad inthis model..probably an electrolytic..but I dont know which one...I have not dug into my set yet, but signal tracing the problem would be a good start.
