Re: radio shutting off when I press PTT
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

Re: radio shutting off when I press PTT
New batteries usually show 8.4 volts fully charged. Older batteries will start to weaken after a while. Your battery showing 7.2 volts will need to be replaced.

Re: radio shutting off when I press PTT
Hello Jayne,
I would say you need a new battery.? They are not very costly.? You could try this link: https://www.hamradio.com/detail.cfm?pid=H0-007324
They are around $35 - Can't think of

Re: radio shutting off when I press PTT
I had just taken the battery off of the charger. The reading was 7.3V. I've taken it apart and there's no sign of fried circuits or bulging capacitors. And I do know that it won't function when

Sounds like the battery needs charging.

Re: radio shutting off when I press PTT
Battery needs charging or replaced. Cannot transmit when plugged in to wall wart.

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

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

Re: DIY Programming Cable
I am defending my laziness!
OK. I will modify the schematic and I will put a link to the schematic you sent me.
Thanks for the interesting discussion

Re: DIY Programming Cable
The official programming set is: Yaesu CT-42 which contains CT-28 cable and the CT-29 Interface unit
The resistor inside the radio is for the Clone function between 2 radios, a resistor is absolutely

Re: DIY Programming Cable
If you look to the FT-60 schematic you will see that on the data line there
is a pullup resistor,
R1168, 47 k, which goes to the 3 V bus (regulator Q1001.)
So no need for an external resistor.

which specification? Is there a specification? You are the only person in

Re: DIY Programming Cable
The specification requires a pull up resistor and a diode end of discussion. To say it's not needed is careless and could damage someone's radio. There is simply no need to be ignorant and

Re: DIY Programming Cable
The way it reads and writes is by pulling the TX and RX lines low, without the resistor the MCU is "Floating" it's neither high or low. There can't be a pull up resistor inside the radio as the same

Thank you for the remark. However I found a diagram of the Yaesu

I thought that the somebody put the diode was there to protect the

Re: DIY Programming Cable
It may work for you, but you do risk bricking the radio if even one byte fails when writing to the radio. I was just being helpful by giving additional information on how it is done officially and to
