Hello, i am trying to use FT817 9600 baud capability along with soundmodems (agwpe and flexnet). I have good operation @1200 bauds, while absolutely no packet...
Hi all Just found out im being deployed by the US military next week and want to bring the 817 along. Wondering if there is anyone out there who can sell me a...
George, there is one on e-bay, two days left. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3033376817 ... From: George [mailto:ne2i@...] Sent:...

Nice use of formulas. Shame they are all based on a false assumption of what total discharged is. Since you are so adamant in proving that my charging...

On the basis that nothing's free, and no system is lossless, I'd figure on possibly getting 7 AH out of a AH gel-cell and putting at least 7 AH back. 8000 maH...

You state: "Personally, I feel..." Do you have real-world experience in this matter? Is this based on experience or just a "feeling"? ... 3 to 4 ... battery,...
Sorry for Pi---g you off! But I do not believe that you will have obtained even six (6) ampere-hours of service from your 7 ampere-hour lead-acid gell cell...
You are right- it's not rocket science. However, one does not "get 7ah out of" a 7aH battery. The starting point for your calculations must be the fully...
That statement was made based on my ACTUAL, real-world personal EXPERIENCE. (not just a FEELING) I have been active with solar power for over 20 years, and ...
... This means it will take two days to charge a battery you used up in one day or you have 21 hours of sunlight. You have to allow if more if you are using a...
The cold, hard fact that you seem to be ignoring is that the 817 (and most other radios) will cease operations at around 11.7 volts. At that point you have...
... Do you even have a FT-817? The internal battery pack is a 9.6V NiCd or NiMh battery. Of course, it works at less than 11.7 volts and even down to about...
hello group! I have a question on something that might have just gone unnoticed up until now... Today using the 817 at two meters, I saw that the power bar...
Did we ever establish what one bar, two, bars, and so on means with the SWR meter on the FT 817? If so, I would like to know. I cannot find any such ...
Okay Mr. EE, prove me wrong with the math. Here is my assertion: Starting from the fully discharged voltage of 11.9 volts, an AGM or gel cell will recharge in...
Ah, now we're back to the 817. The 817 will continue working all the way down to about 8 volts. This is of course much lower than the end-state voltage of a...
I've mentioned this before- the ill effects of recharging a $10 7aH battery do not concern me. If I get three less charges out of my $10 investment I'll not...
... Math is the easy part, I fail to see where you have used any. Which part of AH (ampere hours) do you fail to understand? Your aforementioned 7 AH battery...
Aparently you failed to test your FT-817, and also failed to notice in the YAESU manual, but the FT-817 is operable at FULL ratings, down to a voltage of 8.0...

This is easy. Assuming your charging at 15v for easy computation 15V X 7 AH = 105 WHr of energy must be put into the battery 105 WHr/5 W = 21 Hours. Mark KC9C ...
