All filter switching is controlled from the buttons on the radio. You do have to move the speaker over slightly inside the housing to make space for the module though.

Re: Sotabeams speech compressor
Hi all,
My mic gain is 50 ssb mic.
With the compressor switched off and radio set to 5w and a 12v car battery operating into a dummy load an external power meter shows peaks of 2.5 to 3.5w. With compressor switched on peaks are 4 to 5w.
Tried listening to my audio on my ft450d with a piece of wire stuck into the antenna socket but too much distortion and feedback. So I will be using an online websdr to listen to the audio.
P1 and P2, I tried adjusting them but due to not being able to hear clearly I reset them as delivered, the top just pops off the case to access them.
I did notice that the ALC on the 817 increase a lot when compressor switched on.
Will report back after further testing.?

Re: Sotabeams speech compressor
Hi Andy,
?
I have the same speech compressor from Sotabeams, just out of interest what mic gain setting do you have the FT 817 at with the speech compressor switched on?
?
Thanks

I have no experience with the BHI filter, however I installed the sotabeams filter in my 817 and it's great.

Re: Sotabeams speech compressor
Hi Andi, I don't quite understand how to adjust P2? I haven't read the manual yet, because I thought it was a plug and play product, so you have to adjust the voice a bit as I understood you? I wonder how long it will take until I have everything I need to go up the mountain.?
?I have an Ft817ND with Z-817 tuner and then the sorabeams filter and the sprach amplifier and I'm still thinking about whether I'll also install the parrot microphone. Let's see. Thanks to all of you for your help and tips. Now I just need a good antenna solution, I have long wires with splitters, I just need to mark the length and then I only need a single wire, what do you think? At the moment I still have the beginner's license as HB3 (i.e. DO for Germany) I am not yet allowed to use any bands.

Re: Sotabeams speech compressor
Thanks for your feedback Andy.?
I tested in ssb an FT-817 with a external swr/wattmeter and was very surprised to see no more than 2.5w even with ssb mic gain set to 95 and shouting into the mic !
I better understand now why such compressor been developped… HI?

Hi guys,
?
I would like to install a DSP filter, who can tell me where the advantages and disadvantages are between the sotabeams filter LASERBEAM-817(FTFM-100) and the BHI filter NEDSP1901-KBD. Is it possible to operate the sotabeams filter from the outside, whereas the BHI filter requires two holes to be drilled.?

Thanks Clyde, it may only be an 817 thing. I've used it ok but am leary to do so.

Re: CAT Display with an CAT Splitter for FT-817ND and others?
I t's very easy to build up an interface between?2 different baud rates with a raspberry pico (a few dollars) because it has 2 uart. So you can set up the FT817 at the slower baud rate and interface the two peripherals.
Maybe you can also set up the highest baud rate if there is no high traffic at 4800 baud.

Re: CAT Display with an CAT Splitter for FT-817ND and others?
Hi again Martin, understood. I also have used an bluetooth Android app called pocket rxtx lite. It is a very nice program but I am leery of using it much since reading that it can possibly brick the radio, or somehow write to the eprom and mess things up…and Yaesu will not fix it.?

Sotabeams speech compressor
Now that better weather is hopefully not too far away I have put together a grab bag of kit for portable working.
I have a Ft817nd and a ft818 for /p use, the 817, z817 plus a couple of wire antennas and patch leads all fit in a padded dog treat pouch, ideal. However it can be difficult getting contacts especially if a couple of stations call at the same time as you.
I also have a sotabeams inline speech compressor, first time I used it was an eye opener. Usually I have to repeat my callsign as the other stations miss a letter or two and ask for a repeat, sometimes more than once if my signal is low. With the speech compressor though I had no repeats asked for last week, 5w from a linked dipole in inverted V in back garden worked all over EU and into Russia. I? was heard first call and received good audio reports, switching the compressor off? and there is a definite drop in signal.?This was with the compressor in as delivered configuration, this weekend I will use another rig to monitor my audio and adjust mic gain on 817 plus P2 on the compressor board to set it to my voice.
Really good addition to my portable setup along with my K1EL K16 keyer.

Re: CAT Display with an CAT Splitter for FT-817ND and others?
Hi Martin, I’m using the Chinese clone on my FT817, non ND w the Z817 LDG tuner. It works well, but the difference in baud rate requires a change for each device. That may be the case for any type of hookup. I watched Chris’s youtube video, but I’m not computer savvy enough to know what conflicts you may run in to. Good luck

CAT Display with an CAT Splitter for FT-817ND and others?
Hi guys, how does it work?
I am looking for a way to add a CAT display?
My question:
Is it possible to add the AT display with a Y-cable?
I have an Ft817ND and an LDT Z-817 tuner in use, and would like to use the original CAT display from the Cris from Australia and not a copy.

Re: Bioenno 9A battery BOGO deal
I bought this, 2 9AHr batteries $100.? I have another I have been using with my IC705 for about 4 years.? The Bioenno are great batteries, much better than the Chinese versions.
Also will work with my FT817.

Im pretty sure the deal is only good in the U.S. (sorry), but I encourage you to look into it, it's a great deal, esp if you goo in with a friend and split a pair of batteries.

I ordered a pair of these batteries, each with its own 2 amp charger for $115 with $10 s/h, so final cost was $62.50 for a quality 9 amp batter and a nice charger. Here is the link to the deal in their website:

Re: Possible place to look " finals "
After 5 days trying different searches I found there are fuses on the main board. Followed the 12 volts in all the way to the fuse which then passes through and to the side where the finals board gets it's power., however the power stopped at the fuse. Now have fuses on the way here to see if I can get the new finals board to power up.

Possible place to look " finals "
No 12 voltage passing through main board to the finals board. Any ideas what components to look for.
