What i need to put multiple receivers with one antenna in my shack all advice is welcome

Banggood is a Chinese vendor of a myriad of items. (A few years ago I bought a tri-band HT, Bluetooth-programable, to use on Allstar, and it's been great.) I see there are a number of IC shortwave receivers that might be interesting or fun to play with. The "SI4732 Pocket Radio Receiver...

I am interested in your experiences in combating QRMs, especially in agglomerations and how the selection of receivers and ancillaries helped to mitigate that problem. How would you compare older professional-grade 19" rack-mounted HF receivers used with preselectors to what is currently...

I need to know why an FM broadcast can't travel too far (from one side of the earth to other) like an AM broadcast that could travel thousands of miles after getting reflected from the ionosphere. Why can't FM signals be sent to the ionosphere for high range broadcast?

I need to know whether the radio receivers that are highly sensitive, like having sensitivity less than 0.0224 micro volts for AM reception, encounter less fading than the others with less sensitivity? Which specification of a radio receiver is responsible for mitigating fading?

So i have been struggling to figure the answer out to this question for a while now. I bought the RTL-SDR kit and i don't know how to configure the antenna, videos on youtube have conflicting answers i see one person say use it one way and then another person in a different video says to use it...

I need to know which antenna among the monopole, dipole, and discone is best for HF reception?

Hello, I am currently about to buy a police scanner sds100 uniden and what i am looking for exactly is to detect the presence of law enforcement officials nearby by only picking the signal (such between 1 and 5 mile away) but i am not 100 percent sure if this device can only pick cell tower...

There is no category that this fits in perfectly, but I think this is the best fit. I am wondering how much RF power (field strength) does it take to blow out a generic handheld AM receiver? If I am about 200 ft away from a 1/4 wave MW antenna and it is producing 1kW, will I blow out my...

Hi there. Might be a bit of an odd one, but I'm trying to research the plausibility of movie story line. During the 70s there used to be clunky old FM system hearing aids (Phonic Ear was a brand) that kids would strap the receiver to their chests and the teacher would wear the...

Pretty straightforward question: Is there a standalone device that can receive such a large spectrum as an RTL-SDR dongle? I'm new to radio usage in general, so I'm open to any suggestions that could make this post and future posts better.

Hey guys, I'm working on getting a mobile setup installed and had a question regarding my scanner. I'll have three radios and my scanner.. 4 antennas total. Scanner has a dedicated antenna. My question is, is there anything on the market that can disconnect the antenna from my scanner if I...

Hello, my team and I are launching a cube sat into space. We are fairly new to radio and are not sure what radio transmitters or receivers to use. We would need to transmit to a distance of about 251 miles, we can have a fairly large ground station, but the transmitter and receiver would need to...

I am trying to figure out how I can hook up a HP2 scanner to my audio system and leverage my speakers. I have a Yamaha RX-V673. But it doesn't have a "line in" interface. Has anyone tried something similar? any suggestions? Thanks,

Hi Guys. I just got a THF6A. The reception and clarity is a bit disappointing. Is this the norm for this radio? See the video I made: http://youtu.be/s9EbIWmlJeg Thanks in advance for your input. Mike

I just watched Apollo 13 and noticed that in the scene where Jim Lovell's wife is in her bedroom she is listening to NASA communications on what appears to be a "NASA" receiver of some sort. I'm just wondering. Was this a legitimate device or a movie prop to bump up the drama? If it IS real...

Hello. Ever since I was playing around with my portable today and I accidentally hit a ceiling lamp (metal..) with the telescopic antenna I've been hearing a "buzzing" sound on my portable. No matter what I do it doesn't go away, there's this "buzz buzz buzz buzz" sound. The radio still works, I...

Hello all, I've been looking in to upgrading to a new receiver. I've been looking at the Yaesu FRG-100 for awhile now, looking possible I could purchase it. Could anyone with experience with this radio give me it's pros and cons? Also, is it good for DXing? able to pull in weak signals good...

We've released more information about the SDRplay RSP... (SDRplay - Downloads) Detailed Technical Information Conceptual Block Diagram Schematics As well as details on the digital AGC scheme and a SDR# plugin. The Windows & Linux APIs are also available for download and Android & Mac are...

Hello, Currently, I was going through thereceiver architectures of navigation satellite receivers. The sensitivity of these receivers is pretty low. One of the technique is to extend coherent integration time for increasing the sensitivity. Can anyone explain me what is the significance of it...
