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 sees perfectly but for some reason it isn’t seeing the lifepo4 battery. I have checked the battery voltage and it is fine, I have a power pole adaptor on the radio but it is fine (car power cable is Anderson). I have checked the battery cable and it is showing both continuity and voltage on the Anderson connector going to the radio, nothing seems to be loose in the connection and I did check the contacts on both sides for corrosion and everything seems to be fine. I’m suspecting the power pole connectors even though they seem fine but I don’t have any to replace these with at the moment Are there any settings that I am missing? It was seeing the connection yesterday just fine but not today. The onboard yaesu battery is suspect right now, I think it’s probably very weak due to age and I am planning on replacing it with the windcamp battery but would really like to know what I am doing wrong. thanks and 73 Kevin K5KTM

Hello, I am aware that this group has nothing to do with /g/ft5dr but I keep getting rejected because my call sign and email address does match QRZ and that is false. I have sent a message but no feedback. Anyone have a contact for that group? regards

Hello, is there still a chance to get a filter for the Yeasu 817nd? I saw some on EBay, but the asking price is a lot. I saw some compatible filters that could be used with a custom filter board. regards,

Hi all, I am making myself some field-notes for the FT-817, referencing the existing cheat sheets and the manual. On page 20 of the operating manual: "If your transceiver is configured for "RF Gain" use, rotating this control fully clockwise in the SSB/CW/Digital modes will provide best sensitivity. To reduce the receiver's RF Gain somewhat, rotate this control counter-clockwise slightly. You will observe an increasing number of bars on the S-meter as you rotate the SQL/RF control counter-clockwise; this indicates increasing AGC voltage, which is causing the front-end gain to be reduced." I am presently confused, as I would expect the S-meter to be more active with the RF gain increased, but the way this is written (and in my experience), the S-meter decreases when the RF gain is increased. This also reduces the relevance of an RST based on reading the S-meter. Am I misreading things? 73

Picked up one of these which turned out to be very good quality. https://www.aliexpress.com/item/33006915461.html?pdp_npi=4%40dis%21GBP%21%EF%BF%A140.96%21%EF%BF%A117.61%21%21%2150.83%2121.86%21%40210384db17169104486316288e4ce9%2167103488115%21sh%21UK%212681419577%21&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2007521708592.33006915461 Basically what Portable Zero sell as their 817 Sherpa II but without the Molle side bags. https://portablezerostore.ecwid.com/#!/817-Sherpa-II/p/57782043/category=21722042 The Portable Zero option with extra bags is probably a fair price but shipping cost ex US is prohibitive. No affiliations etc, just thought it might be of interest. B

Hi all, I've noticed that there are "compatible" knock offs of authentic Anderson power pole connectors at lower prices. Anyone have any experience with them? Springs, contacts? Thanks. Joe N1KHB Sent from AOL on Android

Hello, I was not looking for this specifically, but just found that Aliexpress has TCXO boards for the FT-817. I have no idea if they are any good. I also have never had an issue with the stock oscillator. 0.5PPM Temperature Compensated Crystal Module Compensated Crystal Element for Yaesu FT-817 857 897 - AliExpress 73

Hi folks, I updated the document about the Collins mechanical filters for FT-8xx radios. More Collins p/n and used aliases on the market added to the document including the real pictures as a proof.

The Sotabeam “Laserbeam digital audio filter fitted to the main board would appear to be a serious alternative, or at least worth considering. True or false?? P Burnett -- Peter Burnett G4BLL

Is anyone using this amp with an FT817/8? Is it possible to modify the drive input to obtain 100watts output for 5watts in. With the newer bdx version their is a switch to select 5 or 10 watts drive for 100watts out so I thought the b model might have the same circuitry but just no switch. Where can I obtain a copy of the manual and circuit diagram, pdf or paper. I have only been able to find details on the bdx version. Thanks for any comments/info -- Peter Burnett G4BLL

Hello, I am replacing the SEL rotary encoder on the FT-817 and want to make sure I do it without breaking anything. What size allen key (hex wrench) do I use to undo the VFO knob? I tried using a 1.5 mm allen key but I can't loosen the screw. I don't want to apply undue force and damage something by using the wrong tool. How do I get the knob off the SEL encoder. Do I just pull it outwards while the unit is still fully assembled? Again, I tried pulling it off with some gentle force but it didn't budge. Since the encoder is being replaced anyway I'm OK with applying more force but I want to make sure that I'm approaching this the right way. Thanks Ed

Hi All, Hamvention is just around the corner and QRPworks is looking forward to being there again. We'll be in the same inside booth as last year in building 2...booth 2804. If you're going, stop by if you can and say hi. (BTW, our custom FT-817/818 CAT cables to connect to our SideKar Decoder Edition are back in stock) 73, Shel KF0UR & Steve KB3SII QRPworks, LLC

Hi all, I'm considering a solar panel purchase for portable qrp. Something in the neighborhood of 20-30 watts. Many on the web have sketchy, ambiguous, or contradictory specs. Any guidance would be appreciated. Tnx. Joe N1KHB

I finally decided to attach the side rails that came with my Portable Zero Pack to my 817nd. The two screws on either side are so tight I can only barely loosen one of them. The other three are way to tight and I don't want to damage the Phillips head screw. Does anyone know of a method of loosening screws that are so tight? Appreciate any and all advice. 73 Rich KB3OMJ

Hi All New firmware version V1.3 is already working in Maxicom CAT display for FT8xx transceivers A new IF for 28MHz transverter was added. This video shows Maxicom used in FT8 with FT857 and MET-4 4m transverter https://youtu.be/c9ik0IWgvbE?feature=shared Of course you can also use it for digital modes in other bands not needing transverters like 432, 144, 50, 28, etc https://youtube.com/shorts/Ad4p7K7qG7k?feature=shared Kit price is EU200 plus shipment. ??m sending the main pcb already assembled and tested Anyone interested please contact directly luis (at) vigilant.es 73 de Luis EA5DOM

All, Is anyone using an H-250 military handset with their FT-817 ? Perhaps in a field pack configuration ? If so, I have a bunch of questions; How did you interconnect the handset to the radio? In other words, did you buy a special cable, build or buy an adapter, or lob the U-229 connector off the end of the H-250 cable and add the '817 mic connector? Is the output level from the handset mic high enough to drive the radio ? Is there enough drive from the radio to drive the earpiece ? Thanks es 72, Gene K1NR
