Can any of you give me a suggestion on what might be going on with one of my FT-818nd radio. I have two 818nd Radios but only one has a Collins Mechanical 500Hz CW Filter. I wanted to add one to the other radio so I bought one on eBay. It’s the same as the other which is the XF-115C. It’s my understanding that this filter is compatible with the ND versions of the 818/817. It says Collins Mechanical and Yaesu on the Filter. It was said to have been tested and it’s 500 Hz. The same filter works perfectly on my other radio. After installing the filter (all the menu settings are correct) I did not hear the distinct change in sound when turning on the filter (NAR). I assumed the filter was bad and returned it. I bought another from a different vendor. Same XF-115C Filter. Same problem. This radio is virtually literally brand new. I bought it from HRO when Yaesu announced the end of the 817/818 and am just now getting around to using it. It seems unlikely that both filters could be bad and also unlikely to be the radio as it’s brand new. When I turn on the filter (press NAR) I hear the click, no error messages but the sound doesn’t change in the way it’s supposed to and as it does on the other radio. Sorry for the long question. Anyone have any ideas on what might be wrong?

Does it matter which antenna port you use for VHF/UHF versus HF. In other words (assuming the proper connector) can you use the rear HF Connector for VHF?

Is there anyone in the U.S. that knows and can work on the Neptune 50w external amp (manual band ) sold by 60dbm.com? I purchased one (used) almost a year ago and it does not put out any power on the 6m band. The other bands are fine. Yes, I purchased it used and it arrived DOA for the 6m band. Buyer beware. My fault. Had a local tech look at it and he said there were some issues with the wiring and even with the schematic, was not able to fix the problem. I've since also replaced a whanky BNC connector and the power push on/off switch now needs to be replaced. Yes, I've contacted the supplier/builder in the Ukraine and he said send it and I'll look at it.But, with back and forth shipping costs and then the labor/parts costs I would be out more than I paid for the amp. I recently emailed them for specs on the power switch and still no response. I appreciate Ukraine is still at war with Russia but expected some response. So, while I currently have a 80m-10m external amp I would like to get it to work for 6m with my FT 817ND. Any suggestions? thanks, T, 73

In order to get ful coverage on 23cm 13cm and 10ghz I need to expand my rigs coverage so to give me expanded coverage via my tranverters. I have some optional switches on the local oscillators on the transverters but still will leave me insufficient coverage on those bands any help would be appreciated Mike GD6ICR

..was going sell my unit bot had second thoughts. Anyone know if the Android software is available somewhere? Anyone got a copy? Thanks in advance! -- William, k6whp -------------------- "Cheer up, things could get worse. So I cheered up and things got worse."

I wonder of anyone has “The One Big Punch” adaptation done to their mic by W4RT when he was modding the 817? If so it would be neat to see the difference between “The One Big Punch” and the Sotabeams processor. I think “The One Big Punch” is just a capacitor or a few other parts to knock off the wasted frequencies in the audio but for the price the Sotabeams processor is probably better for one reason or the other. I know the W4RT (BHI I think) audio processor that I had i stalled does make a difference in the receiver but that was the most expensive upgrade W4RT did back in the day. Any thoughts on the transmission audio between the two transmitter processors? Dave K8WPE

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. Andy

is there someone outhere who i could send my radio to so i can have it repaired? as i had it hooked up to a 2 meter amp and something wierd happened and it was backfeed with rf somehow and burned something up somewhere so i need my radio repaired? thanks, jerry w5kaw

Hello, My FT-817ND (bought new in 2004) takes some time to reach 5 Watts after first powering on. Example: apply 12V external supply, power on rig, key down on 28.060 MHz CW. Power is initially about 3.5-4 Watts, and current draw is about 1.6-1.7 Amps. Keep keying down. Current draw drifts up and power output drifts up. After about 5-10 seconds, the rig reaches 5 Watts output at 2 Amps. Thereafter, the rig puts out 5 Watts as long as the rig is kept powered on. I observe this more pronounced on a few bands, e.g. 30m and 10m. If I give the rig 13.8V, the time to reach the 5 Watts output after power-on is shorter. If I turn the rig on, leave it on in receive mode for a several minutes, and then key down on 28.060 CW, I get the 5 Watts at 2 Amps immediately. Is this normal behavior for this rig, or is it a sign that something is aging and should be replaced? 73 Mike N9OHW

My FT-818 shows 3 bars on the SWR meter on 70 cm at the 5 W setting, when connected to a good quality UHF/microwave dummy load. On 50 or 144 MHz it shows zero bars. This is true for both front and rear antenna connectors. The output power is indeed 5 watts, measured on a Coaxial Dynamics meter. I have tried a couple of good dummy loads. Can anyone comment as to whether this is normal behaviour? A local says his FT-817 shows zero bars on 432 MHz on a good load......so is there a change from the FT-817, or is there something amiss in my '818? 73, Steve VE3SMA

Hello, Does anyone use the Digirig for APRS? How does it work? Daniel PY2TDB.

As a long-term straight key operator trying to get to grips with iambic keying I would like to know whether the 817's internal keyer is mode A or mode B. Whichever it is, there isn't a choice, and I'm convinced that I would find the other mode easier! Any advice, please? 73, John G4EDX-- John Fletcher

Anyone had a look at fitting one to an FT818 as the spec seems to same but what attachmnet point for the tap and power Mike GD6ICR
