Although the Delta IV Heavy is a massive rocket, I do not expect the launch to be very visible beyond 50 miles. The most visible part of the launch for observers in outlying areas will probably be a short white contrail created when the Delta passes through altitudes of about 30,000 to 35,000 feet.

re: "I heard the other day that another 7 cube SATS have been released into orbit."

I don't want to sound like I'm doubting you -- but I heard that another 7 Iridium satellites (not cube sats) were launched into orbit.  I wonder if one or the other of our stories got them mixed up.  It seems many press stories get passed around so many times, these days, they might get the details wrong.

Re: Vandenberg Launch

LAUNCH UPDATE: The ULA Delta IV Heavy carrying the NROL-71 mission launch date is under review. A new launch date and time will be provided pending the results of additional testing.
 
“We continue to remedy the technical issues that caused the last scrub of the Delta IV Heavy, and are working with our partners, the National Reconnaissance Office and the U.S. Air Force, to ensure that we fly when it is safe to do so,” said Gary Wentz, vice president of Government and Commercial programs, “we understand that this is a high-priority mission for the nation’s warfighters and we take our commitment to safety and mission assurance seriously.”


QSL Card for ISS Reception

Clint Bradford
 

Did you know you can receive (pun intended) a QSL card for merely receiving signals from the ISS?

You do not need to complete a voice contact with an astronaut ... If you simply receive signals, or receive 
SSTV or packet - you can acquire a QSL card!

Per the ARISS.org Web site - 

Please send your QSL report by mail  to the address of the office listed below for your region. Include in your QSL report: date, time in UTC, frequency and mode (voice, packet or sstv). If you wish to receive a card, you must include a self-addressed, stamped envelope with proper postage or with sufficient International Reply Coupons (at least 2 IRCs). 

Email addresses listed below are provided for inquiries only-- you must apply for QSL cards by mail.

Re: Extending HT Battery Life

Clint Bradford
 
Edited

According to the Cadex Corp ...

"The Eneloop NiMH by Panasonic and Sanyo has reduced the self-discharge by a factor of six. This means you can store the charged battery six times longer than a regular NiMH before a recharge becomes necessary. The drawback of the Eneloop to regular NiMH is a slightly lower specific energy."

The manufacturers of Eneloop also state their cells can be charged up to "2,000+" times - which is a little 
contrary to existing literature on the NiMH chemistry. The Eneloop "Pro" only "500" charges.

First inquiry of 2019 ...

I tend to stick with local dealers or otherwise well-respected battery suppliers for aftermarket cells/packs. 
There's a lot of rubbish out there ... with either no one to contact for support, or expensive or non-existent 
return policies.

The stock NiMH pack for the Yaesu FT-60R is the 1400mAH FNB-83. About US$36 at Yaesu dealers everywhere.
Properly charged, you should achieve about 1,000 discharge-charge cycles from quality NiMH packs. 

Personally, I still use the empty Yaesu FBA-25 AA "shell" and populate it with 2700mAH Maha NiMH AA
cells. That instantly nearly "doubles" my run time (from stock 1400 to 2700mAH).

I further increase my run time by improving my antenna, and turning DOWN the TX power to 2W. I mean, 
if you are not making it line-of-sight with a decent antenna at 2W on 2M and 440 - then you're probably not 
going to make it at full TX 4-5W power. (Example: I worked the ISS FM voice when it was a few hundred
miles downrange at 2W and a handheld tape measure beam.)

I FURTHER increase my battery run time by using a headset or speaker-mic. What eats up batteries? Keying 
the mic and transmitting, and turning up the VOLume of the received audio. What is the first thing you do when 
you have a shoulder-mounted speaker-mic or are wearing a headset? You turn the VOLume DOWN.

SO ... Just using the stock 1400mAH battery packs - there's how to more than DOUBLE time between charges: 
improve your antenna, turn TX power down, and use an audio accessory!

There are Li-Ion packs for the FT-60R. The advantages pf Li-Ion are that they will maintain their charge longer 
than NiMH, and they perform better in freezing temperatures. And they weigh a little less than their NiMH 
counterparts.

Personally, I do not charge up a radio and put it away for months - to be used later. And I do not live in 
a frigid region. And the minimal weight difference? Nothing to get excited about.

BUT - quality Li-Ion packs will only provide about ONE-HALF the total number of discharge-charge cycles 
as NiMH provides.

And so it goes ... Happy 2019!
