Am, FM or SSB has nothing to do with whether or not signals are absorbed by the D-layer. The factor affected by the D-layer is frequency. And contrary to stated beliefs, it does not disappear at night, it simply becomes less ionized and therefore more permeable to RF.

Well I'm sorry that I lost 45 minutes of my short life on that.

New flavor: Butt-ered popcorn. I always thought it strange that corn will pass right through the digestive tract intact.:whistle:

The radios which you linked to are both marine VHF radios. That means that they may not be used (legally) for point to point on land. That being said, there many hunters in this country who use them for hunting, but occasionally one will get caught and fined. The range you can expect is...

In most cases HF frequencies need a license. There are some marine frequencies which do not, as well as the 11meter band in the US. You will have to investigate which frequencies are legal in Tahiti. Even if some frequencies require licenses, there may not be an organization to enforce...

Most people report that VHF is the superior mode in the forest, especially if there are a lot of pine trees. You didn't say where you Will be using your radio and there may be different restrictions where you live(France?). Do you have a ham license? That would open up a lot more frequencies to...

The learning curve with mine has been very steep but very fun. Not having had any previous all band radios to compare to. It seem to run very warm when turned on. I'm not talking about getting hot with full power transmitting (it seems to handle that just fine). It seems to get hot while just...

Indeed they are, but a half wave Marine VHF antenna is not 12' long. I'm just picking knits. It's a bad habit I have. I know that Wire Weasel knows the difference.

Since when does Marine VHF operate on 7 meters? A 160Mhz half wave antenna should be around 3 feet long. Perhaps you are refering to a colinear high gain array. Marine VHF radio - Wikipedia, the free encyclopedia

Yes, both the author and myself are referring to VSWR, being that the cheap SWR meters we are discussing don't directly measure ISWR or PSWR. My beef with the article is not that his reasoning isn't sound regarding misconceptions about antenna/feed line matching, But rather with the fact...

I may be off on this one but I'll put it out there anyway. I have a problem with The author's myth #8. The writer makes the statement that a particular coax length can not change the SWR of the line . He is very correct in that The coax length has nothing to do with the antenna or feedline...

For ultimate transportability, the Diamond SRHF40 which is the SMA version of RHF40 could simply be left on the radio permanently without the need for a SMA to BNC adapter. Diamond RHF40 Amateur HT Antenna

Ok then yes, all three Yaesu radios you mentioned will handle the marine frequencies as well as WX. I have honestly never ever used the 6meter or 1.25meter capabilities of my VX-8R, mainly because there are no 220 or 6meter repeaters in my area. I have not really used the APRS feature either...

The VX-8R has VHF marine frequencies programed in as one of the special banks, however it will not allow transmission on any of the special bank frequencies. In order to transmit on the desired frequencies, you will have to perform the wide band mod which is very easy for someone with fair...

Yes.

AM and FM are not related to frequency or how the propagation occurs. They refer to the way in which the radio signal is produced and decoded by the transmitter and receiver. The most common mode used on VHF(30Mhz-300Mhz) and UHF(300MHz-3GHz) frequencies, which are both generally considered line...

They knew better than to piss you off Mole. :wink: For your next move, tell them to provide a firmware update for the FT-8900 which will create memory banks, and open up 11Mhz.

Well I finally got some time to play with my radio today. This afternoon I strung up a 20meter folded dipole about 60 between two spruces. The band was closing this evening as I was trying to make a contact or two and got two returns to my CQ but the band closed up just as they were replying and...

Yes 14.275. There was some clown on there who didn't give his call, who was going on and on for like 45 minutes about how he was going to sue some other guy and some really foul insults were flying all around. It was honestly worse anything I have ever heard on CB.

What gives? How is this allowed by the FCC?
