The FT817 Group averages over 500 (+/-130 one-sigma) messages per month. Because the volume of messages is rather large, I would like to remind everyone of a...
Depends on the band. There are several 817 sites where the authors have spent a bunch of time testing the accuracy of the indicator. IIRC, the bottom line was...
Check it against a 3-5 watt resistor used as a dummy load. After that put a meter in line. Mine is spot on with the end fed tuner I built from Steve Yates site...
Yes, with a purely resistive load it will go 1:1 with an SWR meter, IIRC. However, if the load has some reactance it will be off slightly compared to the SWR...
Actually, I think I got that bass-ackwards -- see the KA7OEI site posted previously for an explanation. http://www.ka7oei.com/ft817_vswr.html I use one of the...

... Right, I use one of those too, and it does do a good job, but it still doesn't give any numbers. The NorCal power/SWR meter that Song designed, is great. ...
Hi all I recently put an old (probably 25 years+) 2m & 70cm collinear up on my mast and have an odd problem with SWR readings on my meter (Avair AV-601) not...
If you have an MFJ-416, (NOT 415B) plug-in CW Board/Module for MFJ-9402/06/10 (enables CW) that you don't need, please contact me and advise price you want. ...
Can you beg, borrow or steal an MFJ antenna analyzer? Alternatively, <gasp> get a CB SWR meter. They work Ok on 2 meters. Go from there. Also, make/get a...
Sorry for the late reply on this. Just back from 2 weeks portable ops in the Maine woods. Happy to report the pack preformed very well. Better than I...
On my FT817ND when I try to transmit out of band the display blanks and then shows TX ERR and NOTHING else. Not much help on figuring out what frequency it is...
Hmmm.--I guess we might have to select REVERSE to find the frequency, as it would then become a "Permitted" frequency, for RECEIVE??--(My radio WILL transmit...
Yes - I was thinking that mine works just like that too. But there are some on the list that are just not worth arguing with. Very happy you got it figured...
I have been given a Elite Lipo battery 48oo mah.. 25C.. What battery charger do i need to charge it ? I do have a multi 4 charger for A123 batteries.. Will it...
NO, the A123 charger will not properly charge a Li-Poly battery, as the cell voltages are different, as is maximum safe charge current. The charger you need...
Yes Bill - the multi-4 charger will charge just about anything. BUT... you must select the proper battery chemistry from the menu. I use mine on A-123 s,...
I came across some reading material on how to make the radio transmit at 10 watts. This would seem a bit risky to do and I wouldn't expect much of a ...
So you have not noticed any difference between 5W and 7W versions? ... The internal battery connectors are rated for 2A current(5W TX), something may fail if...
I operate almost exclusively QRP CW with an odd collection of QRP rigs: -- Small Wonder Labs rigs for 80, 40, and 20. -- Old S&S Engineering 80, 40, and...
Go into the message archives, and pull up the thread "817 problem", starting with message 77916. Bottom line: there is an internal SMD fuse that is probably...
Thaks for the reply to this. It looks like another job for Yaesu UK to play with. Best get on the phone to them for to get that fuse replaced. Will 2E0WHN...
Yesterday I received Signalink USB and setup was a breeze. Using PSK-31 Deluxe I was able to send out a signal with no problems. I have run into an issue...
Dick, could it be that your FT817 was in USB or LSB mode instead of DIG? Can you connect an external power meter between the RTX and the dummy load/antenna and...
