My older SH Hx2606 will only 'beep beep beep' when trying to send on any working channel. The weather channel works, and I can't tell if it is receiving. Any ideas? Probably time to buy a new one anyway.
I'm guessing you have a weak battery that will not take a full charge anymore. It takes a lot more power to transmit than it does to receive.
I had similiar problem with an older Standard Horizon HH150. Battey replacements were not available from Standard Horizon. I found a company online, "The Nicad Lady" and she was able to fabricate a replacement battery pack for me. In fact, she upgraded the battery to Lithium Ion, which had much more power and a longer life. I believe the battery pack was around $65. Had I chosen to go with a standard Nicad replacement, the cost was around $50.
That said, handheld VHF radios are cheap now. You can get them for less than $100 new and not have to go through the trouble of getting a new battery pack.
