Re: Measuring the output power
You can build a simple RF probe but you need to calibrate it. ?A simple SWR meter does not measure power over a wide range of frequencies. ?If possible, borrow a Bird 43 wattmeter from a local

It sounds like you need to look at the radios reference frequency/tcxo if it has it fitted, Or the std module, Dave 2E0DMB [email protected]> wrote:

Re: my ft 817 flashes unstable
thanks for you reply i have everything on display but the bands flashing dont work? only when i put voltage up to 14 volts some bands about 4 only become stable

Flashes?? Does it indicate anything on the display?? HSWR, or something else?? Do you have a battery installed? -- Al Skierkiewicz WB9UVJ

Re: Measuring the output power
Multimeters rarely will measure above a couple of hundred Hz.? You could use an RF probe and a dummy load.? I bought a Surecom power meter on Amazon a few months back for UHF and VHF.? They also

And with a good dummy load. Or use a terminating wattmeter such as the Bird 6104 Which has scales down to 2W FSD. 73….Eric VK2VE. Sent: Wednesday, June 26, 2024 1:55 AM To:

Re: Measuring the output power
The best way is with an accurate wattmeter. I have a Bird 43 with an assortment of slugs, including 5 and 10 watt slugs for HF, VHF and UHF bands. Zack W9SZ [email protected]>

my ft 817 flashes unstable
Hello , Have you encountered this problem? my ft 817 worked very well for 2 years in digital mode, now it flashes on all bands if I increase the voltage towards 14 volts it stabilizes on a few

Re: Measuring the output power
And don't forget to check the rf output on the 6 bands mentioned in the service manual in case a golden screwdriver has been in the alignment menus, there are 24 outputs in total that can be

A swr meter aint gonna give you a power reading is it, its gonna give you a swr reading, unless you get something like a cross needle power/swr meter or the like, as for the mulitmeter, err i dont

Hello, Beside getting a SWR meter is there a different way to measure the actual power from the ft817? ?Could I use a multimeter? regard,

Re: Power question - Battery related
Hi, I personally use 4 Li-Ion cells and I get more than enough capacity to tackle mountain outings in QRP. with an excellent power/weight ratio. Since 4 cells produce a higher voltage than the

Re: Power question - Battery related
Well it turned out to be the battery. It’s been working well for a while (10 months or so) but didn’t have enough poot for the radio to recognize it. I ended up putting my much larger 12ah that I

Re: eBay filters
Thanks John. I don’t have much use for the CW filters as I am an SSB op. Haven't used CW since my test haha. I think I’m going to skip the filter entirely. Doesn’t seem to make enough difference

Hi all. I am experiencing a weird situation, I apologize ahead of time as I am a newbie to the 817. When I plug in an external battery the radio is not seeing it. I have a car power adaptor which it

The only good filter is a cw one by Yaesu The Yaesu SSB filter is a bit better. qRP ARCI has an article on them and the graph showed some tighter skirts but I found it wasn't worth $279 Canadian for
