I don't believe it! I have been trying to implement frs for casual non-license communications for many years between neighbors on our block with no luck.
I know it's not my indoor antennas as I can hear plenty of sinals including an occasional weak signal from a 70cm ham rig near by.
Any form of radio by non radio/internet/cell phone devotees is frowned uponed.
What is the url of CERT member holding frs radio?

|I have not really made many "friends" on Facebook for many years.
The only Facebook members that I seem to have any thing in common is other hams! but I have not been able to search or have them show up in my "possible friends" list, how can I search for more ham radio (preferably hams having a tough time financially as I am) operators on FAcebook?

|It's not the battery!
When I opened the case the first thing I did was check the (second battery I replaced with a holder 8 years ago) voltage which was 3.01v and the + battery lead looked soldered.
Since the battery was ok it must have been something else.
I had to pull the shield up to look under as I thought the + lead must be broken.
I couldn't get the shield loose as the tiny sheet metal screw was blocked by the ptt button GLUED! in place.
With the new battery (3.5v no load) in place I couldn't get the screw that holds the speaker and the shield on tight.
Unless the factory battery was attached elsewhere then soldered to the shield as I had done, this caused an intermittent over the years.
There was even a plastic tape insultating the shield from the ground!
I could not get the screw under the ptt switch so I left it out.
I placed a star washer between the speaker mount and no 4 sheet metal screw.
I almost had a heart attack when the display went on indicating 144mhz! after what I had been through.
I think soldering the negative lead to the rf shield (unless I did this) was a factory goof.

|I recently got the message er-2 on my Radio Shack htx-202 handie talkie.
I assumed this was the same message I got 8 years ago and changed the memory backup battery.
When I replaced the battery I got the message in the window er-1.
Perhaps it wasn't the battery.
The manual was stolen out of my storage locker some years ago so I had no instructions on how to turn the radio on again.
I fear the tiny wire connecting the battery under the lcd display is broken and there is no way to fix it.
I tried every thing, holding different buttons and turning radio on, holding buttons the placing battery on base.
It appears toast! I can't believe it I have had so much luck with this radio over the years.
|ghz frequency loop yagis||WD6EJN||on 19/2/16|
With the exception of a qst article some year back a loop yagi for Wi-Fi made out of key rings!
I notice most of the loop yagis above 1296 are just metal discs.
As one goes higher in frequency loops made from wire become inconvenient.
I wonder if the gain goes up (besides bandwidth) when metal disc are used? capacitance would be an issue and wonder if the disc elements should be mounted perpendicular to each other.
I have seen loop yagis where this was done, this may have been for static collection on a weather station, rather then an antenna.
Also, measurements using my common tape measure and calculator are becoming obsolete, maybe this is why it is so rare to find this information, actually I found inches to be more accurate then metric, as it is easier to estimate the final value, remember measure ten times and cut once!
I also can't find if these are attached (brazed, soldered) to the boom, which would dictate the antenna would not work if the boom went through the center.
