The magnetic in the Palm Radio Paddle attaches to the side of the Eagleįlagpole buddy holds the mast extending up to 35 feet I assured her I'd set it on the seat when not in operation, but I still received "the look". I was using my Ten-Tec Eagle on the dining table, and my wife was not-enthused with having half of the dining table consumed by my bleeping radio. I bought a stellar thing called a "flagpole buddy" to hold my 30 foot telescoping mast on the ladder and wallah, I have a portable Ham shack. That cable TV output now takes my antenna connection out of the camper without drilling any holes. In preparation for the upcoming camping season in our RV, I wired a spare 12v 25A circuit in the camper's inverter to bring 12v rig power to the dining table, and co-opted the 75ohm cable running to the cable TV output outside the camper for watching TV (why would anyone watch TV outside the camper). Surely ham life must be better when I can gaze at the equivalent of a smart phone on the front panel when using the oldest operating mode known to man? The KX3 interfaces wonderfully to my Computer The GRC/9 has the operating interface of a Slide Rulerīut wow it's fun to operate. or in the case of my GRC/9, the front panel equivalent of a Slide Ruler. It's just not fair that I'm staring at a segmented LCD display. Many of my QSOs now are with operators that have shiny new rigs. The problem is these newfangled rigs with their dang, pretty front panels providing information overload with aluring displays of 3D waterfalls and teleporter controls (maybe I mis-read that last one in the specs). I had to recently replace its T/R relay and the encoders need some cleaning, but it still sounds beautiful. I've been well pleased with my collection of RF generating and receiving gear for quite a while. I also have old crumugeonly radios that require the patience of Job to operate. I have a KX3 that does everything including ironing my pants (well almost) and a Ten-Tec Eagle that has the smoothest CW anyone could ever want. In the video below I demonstrate the signal rejection of a 40 dB over S9 adjacent signal to a weaker S3 - S5 signal. The real benefit should come in the form of adjacent signal rejection. So, from a selectivity standpointthe 300Hz filter doesn't gain you anything over using the digital filtering with the 500 Hz filter. So what you are actually "hearing" when you switch back and forth between the filters without changing the digital bandwidth is the reduction of the higher frequency noise that can be accomplished using the bandwidth control alone with the 500 Hz filter. Engaging the 300 Hz filter lowers the volume a bit (3-6 dB) due to insertion loss. When you digitally narrow the bandwidth of the 500 Hz filter to 300 Hz you will "hear" the same reduction in noise as you have cut out 200 Hz of higher frequency sound. But try this: Select the 500 Hz filter and narrow the bandwidth (using the bandwidth control) to 300 Hz, then switch to the 300 Hz filter. If you casually switch back and forth between the two filters on a noisy band, it sounds like the 300 Hz filter markedly improves selectivity and quiets the noise. The 300 Hz roofing filter is twice the size of the 500 Hz filter so it must be twice as good right?
