THE FCC PERMITS LANGUAGES BESIDES ENGLISH?
SteveShannon replied to JHENRY's topic in FCC Rules Discussion
Yea, but it’s a pedantic take. After 20,000 - 30,000 years of having evolved languages, tribal customs, and even recognizable physical characteristics Native Americans deserve the title. Or, for the pedants, we’re all simply immigrants from Africa. -
That’s right; the software works differently than Chirp. As others said click on the caret. Disregard Socialmisfit. In fact add him to your ignore list. He never has anything useful.

I put together a hotspot for ham radio. Tonight I picked it up while driving on the interstate about half a mile from my house. It continued until I was nearly a mile away. It has 10 milliwatts and a 3 inch antenna. I was surprised. I already owe you beer!!

Comet 712EFC -- no ground plane radials
SteveShannon replied to WRTC928's topic in Equipment Reviews
KY jelly is water based, not petroleum based. -
You have to match levels and impedances. That’s frequently done using an audio transformer. What is the output impedance on your radio? It’s probably 8-16 ohms, but your manual should say. Is it a speaker output or a headphone output? They have different levels. What are the specs of your audio input on your PC? Amazon sells cables that match outputs to inputs, but you really need to know what you’re matching first. Another way to do this is by placing a speaker and microphone close to each other and letting them couple audibly, but there are drawbacks to that as well. Good luck, Jacob!

Comet 712EFC -- no ground plane radials
SteveShannon replied to WRTC928's topic in Equipment Reviews
Once upon a time aluminum was used for house wiring but there were fires in some places. It’s a little trickier to work with aluminum because aluminum oxidizes very quickly and aluminum oxide is a pretty good insulator. We still use aluminum for utility conductors but with quite a bit of extra training to do it right when joining copper and aluminum. Gil @WRUU653 would be much more likely to understand the process than me. But that’s at DC and and 60 hz. RF travels through molecular thin oxide layers pretty well and I agree with you that stainless steel and aluminum don’t appear to bother Comet. -
I wasn’t thinking about cross banding as much as having a dedicated antenna connection for the 10 meter antenna.

Nice review, entertaining and informative. I apologize if I missed it (and I did go back and reread it), but does it have a single SO239 or one for each transceiver?

Retevis RT97S repeater service required
SteveShannon replied to WRUY699's question in Technical Discussion
Karl, Although it was the voltage regulator that failed that’s probably just a symptom of a high current problem with the boards which draw from power from it. Repairing or replacing the power supply will be repetitively frustrating unless you find and fix the actual problem. I would recommend sending the repeater to Retevis after contacting them using the email address Gil provided above. Best wishes! Please let us know what you find. -
Wouxun KG-935H beeping during area change
SteveShannon replied to 73blazer's topic in Equipment Reviews
Turn it into Wouxun support. Maybe it’s unintentional and they’ll fix it in a firmware update. -
You can’t unless you’re a premium member. Don’t worry about it though. T-sql requires a tone on receive. Tone doesn’t. You can hear a repeater in T-sql IFF (IFF = if and only if) you have the correct rx tone programmed. If you use Tone you will hear everything on a frequency, regardless of if it includes a tone.

I’m sorry I cannot give you the trophy and the laughing emoji both!

TD-H3 transmitting but not showing up on SWR meter
SteveShannon replied to hxpx's question in Technical Discussion
How many were DOA and how many died after being programmed? I’m not saying you made a mistake; I’m simply mildly curious about the sequence of events. -
He didn’t initially bring broadcast TV up; you did. All he did was reply to your comment from Saturday:

Anyone know where to find a Kenwood TK-890H?
SteveShannon replied to WSHF732's question in Technical Discussion
There’s a guy named Steve who sells them to people all fixed up for GMRS. Of course for GMRS use they must be limited to 50 watts. -
Nope, no stars between us and Voyager. Voyager is 15 billion miles away. The nearest star (other than our sun) is 23 Trillion miles away.

Question: Paid Subscription Repeaters?
SteveShannon replied to wilbilt62's topic in General Discussion
But why not just setup a repeater on one of the other pairs? Nothing is gained by intentionally running interference (and yes I appreciate that you said you wouldn’t.) -
That’s correct. For UHF it’s several percent further than the visual horizon.

GMRS repeaters northwest Louisiana
SteveShannon replied to WSGH650's topic in National and Regional GMRS Nets
I'm sorry. In the context you intended it was not snarky. I must have been overly sensitive that day. -
Although Diamond doesn’t specifically say no ground plane, they do declare that the antenna will work nearly anywhere on a vehicle:
-
Not the radio battery but perhaps a small battery or super cap installed on the pc board whose only purpose is to support the chip that stores settings. But I agree; the failure you’re talking about would destroy your confidence in Wouxun.
-
I’m the worst at thread-creep, but this sounds more like the battery or capacitor than a chip failure. In a computer it would be like the battery for the real time clock.

High Frequency (HF) amateur bands have the greatest range, but propagation can vary. Yesterday I was easily able to talk to a ham many hundreds of miles away (Butte, MT to Chelan, WA), but at the same time I could not hear a ham who was thirty miles away in Anaconda, MT because our signals were passing over each other’s heads. GMRS has no range advantage over amateur UHF. Neither does amateur UHF have a range advantage over GMRS. Their ranges are practically identical. But, there are many times more amateur repeaters than there are GMRS repeaters and unlike GMRS the amateur repeaters may be linked together in networks. On Saturday I used my 70 cm handheld and talked to a repeater 30-40 miles away which was linked to a worldwide net at the time.
