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

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

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

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,

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,

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

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

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

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

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

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

Mike (call sign?) wrote… If you use AM for tuning, the carrier is reduced to 1.5 W or less no matter what power level you have the radio set for. It gives you a reduced power signal for tuning

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

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

Thanks Eric. I think I understand your reply. Yes, I can change the CAT rate to 4800 in the FT817 menu and the display will work when connected with the mini din cat cable. The Z817 tuner requires a

The Elecraft T1 only uses the analogue voltage band data. I made up a splitter cable with 3.5mm jack and TTL RS232 converter to 9 pin serial for CAT (which works with a USB adaptor). I set the FT817

Unfortunately, the Z817 does use proper CAT commands to set the FT81x to low power transmit when tuning. It's fixed at 38400 baud, so the pass through won't work for the OP. You can use the Z817 as a

Hi Michael, If I’m not mistaken, the tuner only uses the Band Data pin from the radio to tell it what band you’re on (plus Gnd and power, of course). The CAT Tx and Rx pins are different
