radio shutting off when I press PTT
|
Hello,
I'm new to the group and somewhat to ham radio. My Yaesu FT60R worked fine yesterday. Today I can hear on the local repeater but when I try to transmit, the radio turns off completely. It comes back on when I release the PTT button. To my best knowledge nothing has changed since I was yakking away happily on the local repeater yesterday. I've looked at the manual, which sadly has no troubleshooting section. I've also searched messages here to no avail. Is there a direction I can go to solve my problem? Thanks in advance! FYI if it helps: the repeater receive frequency is 147.120. The offset frequency is 147.720. These things were programmed into the used radio I bought so if it's a sudden programming error, I didn't do it! LOL Jayne |

Just an (educated) guess, bad or discharged battery?

Sounds like the battery needs charging. Dave - WB6DHW On 10/28/2023 1:18 PM, Jayne Rising via groups.io wrote:

Hello Jayne,
I would say you need a new battery.? They are not very costly.? You could try this link:? They are around $35 - Can't think of anything else it would be.7.2V (after charging) is a low battery and this voltage I believe means it needs to be replaced.? Not enough power to transmit.? :)? I would purchase the OEM Yaesu Battery.? Really worth it. -Scott? |

Jayne, you aren't being treated as you think. What you are describing has happened to all of us at least once, and the problem was a low or faulty battery. Do you have a second battery or know someone whose battery you can install for a test and see if the same thing happens in your HT?? Also, what happens when you reduce output power and transmit,using your present battery??

Agree with John Thacker.? Sometimes odd things happen, but the answer may be more simple than we anticipate.? I have worked with tech support with computers for many, many years.? I always start with what "may" be the most simple answer, and then work from there...just as we should do in the medical field.? Dig deeper if needed.? Your situation seems very straight forward.? As mentioned, your voltage on that battery is too low after it was charged.? It could be a faulty charger, but it would be best to start with getting a new battery first.? This is most common.?? People are generally like family in these threads I have found.? Some just give straight and quick answers.? Try not to read too much into it.? Welcome aboard!? -Scott

As chance would have it, I do have a newly purchased battery that HRO has to replace because it’s bad. The thing is: I’ve been transmitting at that power level without any difficulty. I was transmitting yesterday at that level. This is the NiMH that came with my radio, which I bought used. The radio was purchased in 2008, the battery in 2019. Why the sudden dysfunction when my HT was working under these conditions yesterday?? I certainly plan to try again when I put it back together tomorrow. Another ham suggested checking for fried circuits and a bad capacitor.?

It's my understanding that 7.2V reading on a fully charged battery is a bad battery.? It should read higher on a fully charged battery if it's a FNB-83 battery.? There is a lot of info on these batteries and checking the voltage different ways.?? Other than that....personally, I don't have an answer.? Hang in there and keep searching.? You will get it figured out.? This is a great and (very) popular HT.

Well, evidently I’ll just have to wait until I get my replacement battery for the new battery I bought because I suspected the one I had was going bad. Tomorrow’s chore is to put my radio back together such that it works. Lessons for a relatively new ham, I suppose. I’ll know if you’re all right about Tuesday. Lol?
Here Im wanting to chew the fat with the locals and I’m having to hang out on the internet because stuff happens. Oh well I guess! I could always listen in on my Baofeng.? Jayne KD9WLM |

You are getting standard and good advice.
Fact is, voltage is only one indicator for a battery. The ability to produce current is more important. Older batts may show voltage but can't supply the current . The FT60 wants 1.5 amps at 5 watts (high) power transmitting. High should only be used IF needed. Generally you can hit a repeater with the Low or Mid? power settings. The voltage you are reading with the radio or a DVM is a surface charge and not under a load. Just like a 12 batt which starts out at 13.3 to 13.5? volts surface charge and drops to the 11.0 to 12.5 needed for use under a load, your 7.2 batt is not able to stay above the needed 6.0 volts minimum and provide 1.5 amps current.? Using the DV VLT menu option, you can see the voltage at idle. Then key up and see what it says. If it goes below 6, it is not charged and able to handle the load. You can watch this with the menu option while you operate a test. It is a valuable function when in the field. At this moment my FT60 reads 7.7V on startup. It reads 7.6V under idle load. If I transmit on high, it drops to 6.6V. If I transmit on low it reads 7.2 V. If the radio goes blank then flashes its display on transmit then comes back on, it means a low batt but can still listen or maybe even transmit on Low power setting. If it goes blank and shuts down, most likely a very low to dead or bad batt. My 2 cents worth. |

Please don't take it in that way. You are getting good advice. Fact is, for the FT60, 7.2 VDC straight from the charger pretty much only nominal as the manual states. It also states 6 volts in minimum and it wants 1.5 amps to transmit on High setting. High is rarely needed when using repeaters, Low generally works just fine. A 12 volt batt routinely starts at a surface charge of 13.3 to 13.5 and works it way down. Under load it will drop to 11.5 to 12.2V. The available current is more important than the voltage. Especially if you transmit at full 5 watts. Your good 7.2 V batt should come off the charger close to an 8 V level. In the field as my FT-60 approaches 7.7 VDC I consider a batt change IF I am having to use High power setting. Again, voltage is only one indication of a batts condition but the amount of current it can produce produce is more important than the voltage level. Older batts can still get to the voltage but not supply the current. Before tearing into the inner workings of your radio, try this, use the DC VLT menu option [FW>0> turn knob or use up/dwn buttons to DC VLT option then press FW to see the current idle voltage] and see the batt voltage is while the radio is receiving. Typically mine is about 0.1 to 0.2 volts less than the startup reading. Leave it there then transmit while watching the screen, you will see it drop. At this moment my batt is 7.7V on start up, 7.6V in the menu. If I transmit on Low it drops to 7.2. If I transmit on High it drops to 6.6V. I use this when working events and such to keep an eye on the batt status. I am never without a BU batt AND a dry cell pack with fresh energizers for that unforeseen situation. the 'Murphy' law as one gent indicated. If the display goes blank and or flashes, then recovers, it is a low batt good enough for receiving at the power level you are trying to transmit at. If the display goes blank, it is a dead or bad batt. Just my two cents worth. Have a great day.

It just hit me.... We didn't ask Jayne, if she has? the proper charger to match the chemistry of the? battery you are using?????
