    Bear with me as I am not messing with you. But we used trees as antennas in the military Hybrid Electromagnetic Antenna Coupler (HEMAC), and some adventurous Hams have used them as well. If you're looking a great Receive (Rx) Antenna most hardwood trees work great. With a Antenna Tuner you can...

    My Beverage antenna is NOISY! Why?

    I built a single wire 40Meter Beverage pointed towards the N.E., 1.3 wavelengths long and 10 feet high (above "antler height"), and it is far noisier than my full length 40M dipole that is up 50 feet. I just can't figure out why; I am using a DX Engineering matching transformer that is...

    TYT TH-9800 Extended Receive?

    Hi all, I just purchased a TYT TH-9800 Quad Band Transceiver. Just curious if anyone has had any luck getting it to receive outside of the preset bands. Specifically I'm interested in listening to 40-45 MHz on it. Thanks in advance! -- Paul W8AFK [or, Wait, Away From Keyboard :-)]

    TX Further Than My RX

    I have an issue I can not seem to figure out. I am able to transmit(TX) alot further than I can receive(RX) I will be on the 52 (146.520) and people can hear me full scale, and I am barely able to hear them. This happens ALOT. So I am confident the problem is on my end. I run an 8800R...

    Question about transmitting

    I bought a cheap low power FM transmitter(one of those little dongle thingys from China) a long time ago and it has been sitting in the junk drawer for years now. I recently got a microcontroller, and was fiddling with the microcontroller, transmitter, and a regular fm radio receiver. My goal...

    I have been looking for MW receive antennas and came across this from Stormwise ( 903-383-7047. Low Frequency and VLF Antennas for research applications. ) and was wondering if anyone here is familiar with these foot-long loopsticks? and if they're worth the mony?

    Receive Audio Quality and Control

    Audio Quality and Control Most scanners and ham radios have mediocre speakers and audio amps. For example my 2 ICOM HF Ham rigs have 3 watt audio amps with 10% Total Harmonic distortion (10% THD). With speakers facing upward, the resulting audio can leave a lot to be desired. Many scanners have...

    XTL 5000 fading receive

    I'm working with an XTL 5000 and it's receive strength starts out fine, but quickly weakens gradually. Nothing has changed in the radio and we haven't had power outages. Also, it's happening on all the channels from multiple radios, so i've narrowed it down to the specific radio being the...
