Yes. Me.
Gene, I usually agree with your posts, but not today.
There are three kinds of hams who benefit from the dx nets.
First, the small station with a dipole, qrp and poor conditions, who could work the control well but is lost in a pileup.
Second, the new ham, unsure of how or when or what to say. He/she can listen and learn.
Finally, the dx. Yes, I was portable TF a number of years ago. On a dipole at the NATO Base Keflavik. I could geerate an EU pileup in a heartbeat... But couldnt cut thru the callers to work one. Try to be on the other side. I really appreciated the net controllers on 20 meters for sorting the US stations so many more could work TF.

Just a sidebar comment.... I am surprised at the large number of "regulars" participating in the several "WAS nets" who also do not use LOTW. I assumed that most WAS net users would also LOTW. Unfortunately, Not true. 73! John, Annapolis, MD

Concur with GWY on NooElec. I just received the dongle (VHF) and upconverter (HF). Works. The challenges were finding the connections (F to SMA, SMA to PL259 etc) and realizing to offset -100,006,000 in SDRSharp. Nice job.

eHam Forums / DXing / RE: Logging Date Format: DDMMYR?

Web developers have been frustrated with this difference for a while.
The W3C says:
"Visitors to a web site from varying locales may be confused by date formats. The format MM/DD/YY is unique to the United States. Most of Europe uses DD/MM/YY. Japan uses YY/MM/DD. The separators may be slashes, dashes or periods. Some locales print leading zeroes, others suppress them. If a native Japanese speaker is reading a US English web page from a web site in Germany that contains the date 03/04/02 how do they interpret it?"

Good idea, Tim. You certainly have options. Several have and will be presented. However may I add some comments, since you noted the FT-897D. An FT-817 or other QRP rig, coupled with a 7-12AH AGM/gel cell (Battery Warehouse) and a good high HF dipole will certainly meet any minimum emergency comm needs. The FT-817 draws .4A on RX. I recently used that combination during our 5 day Irene power outages. Investigate PowerPoles for your 12V connections. Went well. For effectiveness, I even worked QRP DX into A6 on 20M SSB. An FT-897D with batteries is ok. Frankly, I haven't added batteries to mine, since the two 4AH batts limit you to 20W. They drain fast. The FT-897 draws about 1A on RX. For battery ops, connect to that aforementioned gel cell. Also, you might investigate solar generation. The CT Solar site, http://www.ctsolar.com/solarpowerforamateurradiofaq.aspx, might be useful. 73! John, Annapolis, MD

Chris, thanks for the clarification. Got it now. Good question.
Frankly, I've never worried about it. Just set the charge time for 6 hrs. That charge time, splitting the difference among the CHG choices, has allowed me to charge the internal batteries no matter what the remaining charge. Its never overheated in well over 5 years of use.
For the FM LEO satellites I run portable using the FT-817, an Arrow yagi, and the internal batteries.
With regards to some other replies, I too have a 12AH battery that I use for contests.
Hope this helps. 73! John, Annapolis, MD

Chris, the time shown is the charge time remaining since you started a charge session. It is not in any way a sense of the battery charge.
Take a look at the manual, page 15 on CHG, and page 61 on Memory Item #11, time to charge.
I usually charge a low battery for 6 hours. The voltage display then reads about 11-12v. I run it until the voltage shows about 9 or less, then recharge again. The low power display, page 15, usually shows itself at about 8v.
Have fun with the FT-817 es 73. John, Annapolis, MD
