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.

Hello all,

I came across a deal that folks here would likely be interested in, so I'm sharing it here - I have no relation to the seller, just a happy customer.

Bioenno is having a BOGO (Buy One Get One) offer on 9 Amp 12 volt LiFePO4 batteries - and as a friend on another group proved [0] these are very nice battery packs.
?
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.

Re: No transmit function on 2M
Thank you very much. Here the same, but a couple of hours after turning it on, the power goes back to normal.?
I'm not sure I want to spend 130� for the 2m band only... I'm thinking about a heater? ;-)

Hi Neil
Thanks for the info,
Yes it is a big job, but I have done a lot of smd work so I changed the diode myself,
Good luck

Re: No transmit function on 2M
Hi Neil
What did they charge for the repair,
Dave 2E0DMB
Hello from the UK.
?
I have a gen 1 FT817 that I still love.?
?
I have just had your problem and it was fixed by Yaesu here in the UK - they take 3 to 4 weeks to repair and always do a fantastic job.
?
Basically I blew the front end a couple of years back and Yaesu replaced the PA board with the new rugged version.
?
I then lost the power output on 2m a few months back, like you are experiencing.
?
Karl, head of tech.sales at Yaesu UK, diagnosed the fault over the telephone as I was transmitting on all other bands and still had receive on 2m, but extremely low output.
?
If it helps you, there was a faulty switching relay and diode that are used to switch between the VHF and UHF section … the service note from the Yaesu service engineer says “replace Relay RL3001 & Diode D3003 on PA Unit”
?
I hope this helps!!

Yaesu XF-122 C, 500 Hz Collins Mechanical
Filter For Sale:
I have a Yaesu XF-122 C, 500 Hz Collins
Mechanical Filter For Sale. It is sometimes
called a YF-122 C. It also has the 528-8686-030
Collins number on it. It is for a 455 KHz IF.
My understanding is that it fits YAESU FT-817/
857/897/818, and maybe others.
It includes the PC board with connectors.
This one works 100% as it should. It also
looks like new, as if that matters for a
filter inside a rig.
Buy it for $250, plus shipping from Florida.
Thanks.

Hello,
I think I know the answer, but let's see: by the end of the charge (say, 1/5th of estimated battery charge), if I'm TXing SSB or DATA, on 5 W, ALC goes to zero. If I set power to 2.5 W or less, ALC goes back to normal.?
When the former happens, does it mean the battery is not providing enough voltage to the radio?

Re: Winlink with Vara HF and FT-818 via Digirig
The line-level radio "DATA" (really audio) output is almost certainly overdriving the default mic-level input of the DigiRig. The solution is to enable the Digirig's built-in 20db attenuator.
Here's a good video that show's how:
I've done it to 2 Digirigs for Winlink on an FT-817nd, an FT-897d, and an Icom IC-208h. Really brings the transmit audio into reasonable levels. I consider it essential for my puposes.
Here's a good link that explains line vs mic levels:
Hope this helps,

Re: Winlink with Vara HF and FT-818 via Digirig
Rod,
?
is your digirig setup in the duplex serial CAT with logic levels configuration? It can be changed after the fact if necessary. The 818 works with that config but I have heard the trusdx can work in any config.
good luck,

Winlink with Vara HF and FT-818 via Digirig
I've been experimenting with Winlink on my radios and had success with my little trU(SDX) but cannot Tx/Rx winlink with the FT-818.
I have CAT control set up OK as the radio tries to connect with various local RMS gateways, but Winlink always reports that a Failure to connect."
Ive tested a few different Baud rates without success, and have checked the Digirig settings under SoundCard and it seems to me that there needs to be an adjustment to the transmit audio to the radio from the PC where the ALC is adjusted (that was the key to success with the trU(SDX).
?
Anyone with the above combo who have been successful and can chime in? Or anyone with a depth of knowledge about this radio and soundcard combo.
?
Thanks!

Re: Ft817 shuts off at 10 volts?
I just checked the display and yes there is a squarish icon which may actually be a clock that shows just to the left of the L. I guess with my eyesight, I thought it was an square, in place of the L, but on highest power the L disappears. Thanks Mike Davis WA1MAD
