Hi P, I have a few amplifiers, they all seemed to need a higher input to them. I think this element would be better suited to someone more skilled than I am, so I think I'll sell it, and let them appreciate it more than I would. I have an FT 817nd, where it's mic is fine, and I hope to aim for...

Hi B, Thanks, but not much information really. They talk about High low impedance, and I see this one is 2,000Ohms at 1,000Hz, is this high or low? An I want to konw about buying an amp to go inside a mike too. C

Hi, I won a Heil HC-5 mic element in my club raffle, and now I need to know how to get it going. I have an instruction sheet, but it doesn't say whether it is a dynamic, electret or condenser type. Does any one have experience with these and can advise me about an amplifier please? Cheers, Camerart

Hi D, I've just got the sound going. I was using a USB speaker, then changed to computer plug in type, and had to set the sample rate, then it worked. Cheers, C.

Hi, I've just installed SDRANGEL, and it's receiving FM ok, but so far nothing else. With FM I can see signal on the waterfall, and no sound output. I just tried AIS. A plane was registering on DUMP1090, so I switched that off and SDRANGEL on, but nothing. Can anyone see what's missing from...

Hi L, That did it, I can now use the Funcube. Thanks, C

Hi, Just re-read my post. When I said how do I re-install it, I mean the microphone icon, not the program. C

Hi, I have SDR-CONSOLE V3, and am trying to learn it by playing with buttons etc, while reading instructions. I have RTL-2832U dongles also a Funcube +. When using the Funcube, I noticed a microphone icon on the bottom task bar, and deleted it, and the SDR stopped. I think I understand that...

Hi F, I didn't miss it, I came up with a possiblity in #59. If this works, then 2mtrs will 'go' 1000s of miles by relay. (I have my doubts:)) C

Hi m, Yes, I'll think about synchronization later. I use GPS modules, that have accurate timers, this may help. What i referred to as 'the antenna box' will not only have a switch, but electronics also. Again, if this was a viable solution . Yes, I have my doubts, but i'm only idling so...

Hi M, Another good point, most things have been thought of. Anyway? C

Hi, the others concerned with chopping the signal and it's quality and compression. I always try to get round problems. (having said that I know I can talk nonsense sometimes) How about the transmitter, transmitting FM as normal----the antenna box gets the signal, chops it every 20KHz, speeds...

Hi T, All good points. I was hoping that it may make a web similar to the internet. We had a repeater, but it is now in a garage (covid related) I'm only thinking about the idea, not particularly the consruction. I won't go into details, but I've had a ideas in the past, with the same feel...

Hi M, No DMR, as this will only work with existing radiosor it's not worth persuing. c

Hi M, Ok, I haven't investigated compression yet, just the antenna switching. Cheers, C.

Hi all, Sorry for the confusion. Perhaps I'll leave it there, and test to see what this sounds like with only a receiver, and an antenna switcher. From what I gather from some of the replies, it does seem as if it isn't viable. If anyone is still interested, I can let you know how I get on...

Hi A, The radios won't be programmed at all, only the antenna switcher. C.

Hi M, There still seems to be missunderstanding. When you say the receiver jumps back every secondm where did that come from. The receiver will be receiving all of the time, and the antenna will switch back to the receiver 20K/second. C

Hi T, No DMR. The transmitter won't power up as it doesn't power down. More than 20K/second switchng. No repeater. C.

Hi all, I've just had a thought ! When transmitting, then on the switcher will be only switched to transmision, on this radio. When receiving, in order to relay, it will need to capture, a 50% section of the received voice, then transmit it in 50% time, then back to receive. Less than 50% of...
