Sheesh.  Should read ‘9600 baud packet and 1200 baud packet are not compatible’.

Clearly I need to drink more coffee.

From what I understand a station running VARA FM Narrow can connect to a VARA FM Wide station, everything just goes more slowly than wide to wide.

Packet and VARA are entirely separate.  So the VARA configuration does not affect the packet configuration at all and vice versa.

Is the chimney aluminum flashing going to screw up my GP6?

Howard E. Mahran / WA1HEM
 
Edited

Hi all,

I'm planning on mounting my GP6 on the highest point on my house, the top of the chimney. As I evaluated the placement I realized that the top of the chimney is surrounded by ember protection in the form of aluminum flashing (see pic). I'm now thinking I should avoid mounting my GP6 near this as it might cause bizarre distortions/reflections. What do you think?

Re: Battery Chemistry Discussion

Paul Butzi (W7PFB)
 

I keep my SLA (sealed lead acid ) batteries fully charged. The ones not in active use get topped up once a month.

All my HT’s work on LIPO batteries. In theory the battery life is shortened when they are stored with a charge over 80%. The batteries in the get home bags in the car I store fully charged anyway. They get topped up every 2-3 months. This means their service life will be shortened. Ah, well, they’re cheap Baofengtech batteries, and basically the stuff in the get home bag is all considered overhead costs of being somewhat prepared. I just don’t worry about it.

I have fairly expensive batteries for the Kenwood HT’s at home. They tend to be kept fully charged. I know this is not optimal, but frankly the optimal thing is just not very convenient. My policy is that, if the battery on the HT is over 80% I don’t generally put it in the charger. But I have a bunch of batteries, I cycle thru them, and when they get charged, they get charged up to 100% and then put in the stack for use.

This is all in defiance of the best advice. Sometimes the optimal policy is just too much of a PITA for me to follow it, let alone care.

I have to say, I’ve used rechargeable batteries using NiCad, NiMH, and LIPO technologies. In terms of longevity and freedom from hassle, LIPO is the clear winner even with my staunch defiance of ‘best battery maintenance’ practices.

I know lithium ion is probably the worst chemistry for this kind of situation because it doesn't like to be stored at max capacity and the life of the battery is directly determined by how many times you fully charge it. Knowing that, I looked and found every single one of my HTs using Li-ion. So, some references would helpful as well as alternative chemistries, their pros / cons, for both HTs and portable rigs. Thanks!

For radios, the LFP (Life, Lithium Iron Phosphate) have the best characteristics.  Most of the RC hobby batteries are LiPo (Lithium Polymer).  LiPo batteries do not like to be stored charged and lose charge and capacity fairly quickly if they are stored charged.  LiPo batteries are also quite volatile, can catch on fire if they are charged wrong, discharged wrong, or damaged.

 

LFP batteries are completely happy to store in the charged state, have extremely low internal resistance so the charge lasts a very long time, and are almost impossible to catch on fire.  The reason the LFP batteries aren’t very popular in the RC hobby is that they have slightly lower energy density and quite a bit lower peak current capability.

This information source may be of help to you.  My experience is with portable radios.  Every radio I own now use lithiums except for the cheapo FRS radios.

https://mpoweruk.com/performance.htm     Make sure you check out some of the references noted within the article.

Lithium batteries might be what you are looking for.  They have a very low self discharge rate on the order of 2% per month and have no memory.  The depth of discharge is the variable for determining the number of life cycles.  https://mpoweruk.com/life.htm#dod    

Some lithium battery packs like used in the KX2 have built in circuitry that control the charging and discharge limiting temperature during charging and maximum discharge voltage.  This makes sure you do not accidentally damage the battery and shorten usable life.

Raw lithium batteries used for RC application must somehow be monitored remotely during use to prevent over discharge and special chargers are used to monitor individual cells to make sure the cells are properly charged.

Re: Tolt Dam False Alarm

Paul Butzi (W7PFB)
 

Wikipedia suggests the altitude of Carnation is 82 feet above sea level. Where, exactly, in Carnation that would be, I have no idea.

But if the altitude in town is *generally around 80 feet* then a depth above sea level of 4 feet makes no sense, as there will be no place in Carnation that is that low.

Re: Repeater ID question

W7ABD
 

The software for the Cougar Repeater has been updated to reflect CW: KE7GFZ/R and will be applied the next time there is a need to drive up to the mountain and reprogram the repeater.  Such a minor change does not warrant a special trip.

The Bell Repeater (now located at my QTH) Voice ID was changed quite some time ago to distinguish it from cougar.  It is referred to as the "Amateur Repeater" while cougar is just the "Repeater"  It's CW ID will be changed from /D to /R when cougar is updated.

Glendon is correct.  When we moved the original SNOVARC repeater to the Bell's residence we happened to acquire the Cougar Mountain repeater.  While monitoring the activity on both at the same time I wanted a quick way to know which one was active.  The idea came from one of the other repeaters in the building on Cougar mountain where their main repeater was on Tiger mountain and the one on Cougar was the backup.  I can't remember what they used but I think Tiger was /R and Cougar was /C

 

About a year ago I mentioned to Jim  K7ABD that it should probably be changed to /R unless they use the /C and /D when monitoring both repeaters.
