You can buy a genuine Collins 500hz CW filter for about $103 (from Japan, UK etc.) and solder it yourself to an FT-817 compatible board made by Artur, SP6AB. He sells them as a service to fellow hams for $16. Contact Artur to confirm pricing and availability: sp6ab@.... 73, Howard, W6ZZ Here's one possibility to buy a genuine Collins filter (w/o board): https://www.reneegrocery.shop/product/Aor-Mf-500-500hz-Mf-Series-Collins-Mechanical-Filter-526-8693-010-Radio_woy5996ad95856d.html AOR MF-500 500Hz MF Series Collins Mechanical Filter 526-8693-010 radio $111.67$67.00 12 IN STOCK

FT-818 Jedis: Recent owner of a FT-818ND. The book and Nifty manual state there should be four symbols for determining TX power: [blank] - full 6W (5W internal battery) L))) - 2.5W L)) - 1.0W L) - 0.5W I'm using the internal Windcamp battery mod. My screen will only display L)), and L) regardless of the number of times I push the B button. It also seems like there are some extra button pushes in the cycle that don't change anything, i.e. it takes two button pushes to get from L)) back to L). The battery is fully charged. FT-818 veterans, need a brief explanation of the symbology for internal versus external battery sources. Also is 6W achievable with the internal battery? Is that why only two symbols are displaying? If using an external Bioenno 12v, 3Ah battery, is full power an option or am I limited to 5W? Thanks in advance, Matt W7MDN

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,

Hope someone in the group can help. Have a FT817non ND with flashing display. Did all the resets I could find and even did the battery reset mod just in case that was the problem even tho I never did the battery mod or leave the battery in the unit. Had a tech look at it and told me it could be firmware issue. I called Yaesu and they said it's the pll not locking in. Can anyone point me in the right direction to repair it myself. Has anyone had this problem with their radio? All help is very appreciated.

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 bands. thanks for your help 7s de OD5SB Ramy FINGE

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 https://groups.io/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.

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
