Did you try to measure the power? Regards Lou VK3ALB Regards Lou VK3ALB [email protected]> wrote:

Re: PWR level
Not quite right. Blinking will only indicate, that voltage is lower, but power will be 5 watts. 73, Andy DC3AFA

Re: PWR level
This only means the voltage (not power) of your Bioenno battery is not high enough to allow 5W output mode. When a battery voltage is greater than ~ 11.5 volts the 5W output is enabled, when a battery

PWR level
Hello, If I use a Windcamp 3 Ah battery, I can choose the power among the values LI, LII, LIII and LIII (blinking). If I turn off the windcamp switch and plug in a 9 Ah Bioenno, I can only choose

Bluetooth CAT device
I finally got the bluetooth CAT device for my 817 and am using Dan Toma’s Pocket TxRx lite after difficulty on an older Android phone. It is a very slick program. Dan gives all sorts of warnings of

Re: TX Inhibit
Removal of that +Vcc is the final step the sequencer performs when switching to transmit, and the first signal to be output when switching back to receive. Chris Cox,

Re: TX Inhibit
Definitely does work, Andrew. I do exactly the same on one of my 10GHz rigs. If I remember correctly, I have a ~1k current limiter resistor in series between the +Vcc and the TxInh pin. Chris Cox,

Re: TX Inhibit
Hi Andrew, I may help here... My radio is FT-817ND and the plan is to use it as an IF rig for a 10 GHz station. Of course, I needed a sequencer and decided to design and make it myself. Using the

Re: FT-817 compatibility
Thanks Dave, mine is an original non ND. I recently bought a new finals board, just in case. If you’ve seen the external display, it’s a nice option, but does add some clunkyness to the compact

Re: FT-817 compatibility
In my experience of hearing tales of woe (not personal experience) damage to the FT 817 was caused by trying to use a tuner to an unknown antenna for too long of a time. High SWR seems to be the

Re: FT-817 compatibility
Thanks Keith. The 1.5 watts on AM sounds relatively safe. Not sure how much of the 5 watts max might cause the finals damage. I know there have been reported damage, but I don’t know the actual

Re: TX Inhibit
Hi David.....i'm following up a very old post you made back in 2016.? TX inhibit on an FT817.? Did you get to the bottom of it?? Does it work?? It looks like placing 12v on the TX Inhibit pin on

Re: FT817 compatibility
If the LDG only uses CAT to set power and uses the analogue band voltage to know band, then CAT could be disconnected? But maybe it uses CAT to read the frequency. I don't know. As an aside: I added

Re: FT817 compatibility
Mike, I'm glad you are doing the tuning in low power out of habit. Not sure what you mean about removing the internal connection for CAT. Thanks

Re: FT817 compatibility
John, thanks.. I'm wondering if I use manual tuning, by keying the radio on packet, AM or CW mode and not going to lower power, what would be the danger to tune into a mismatch until the tuner matches
