I got my first hustler in 1969. I had a bumper mount and what you have appears to be the part that connected to the bumper strap. I am still using Hustler antennas for portable use on stake mounts or on my trailer hitch mount. I have new masts but my old 1969 mast is still good. It was a fold over mast. I now use the one piece 54 inch masts. All of my original resonators are still good but I have added several new ones. I also use the quick disconnects. I like the top loaded antennas. They have a better current profile that most of the other bottom loaded antennas. That means better radiation from the same length antenna. I have worked over 90 countries mobile with my Hustler on my truck.

It was very adjustable to fit almost all bumper shapes. It was also common for the CB whips of that day. There was one piece that was held tight against the bumper at a fixed angle depending on the bumper.

Congratulations on your new purchase! And sorry for the QMX probs :(. There could be any reasons for it , but my own experience is that the SPS blocks are not so easy to kill :). My first intuitive move would be check and re-solder the encoder's legs with really powerfull soldering iron. I had a problem with my QMX right-hand encoder as it was tuning the VFO somewhat strangely ... Resoldering, esPecially of the ground leg, fixed it. I'm now in the QMX+ building process, and I need a 100W soldering iron with fine tip, as ground points are even more difficult to solder than in QMX, as in PLUS the multilayer ground plane is much bigger.

Hi Linus, any chance of you repeating this but with a QMX ? So comparing SDR vs SDR.
@Linas_LY2H
@Linas_LY2H 20 күн бұрын
Hi OM, sure, why not :) But not because of "comparing SDR vs SDR". In my experiments, I compare the performance of radios, independently of technology, employing the parameters that are universal for all, thus, comparable, like sensitivity of the receiver, or ability to cope with strong signals nearby etc. BTW , the radios in the Sherwood's list are ranked exactly by their performance, independently of their technology. And it's only natural to do so , IMO, otherwise , what should I compare the hybrid radios with if following the principal of "comparing sdr vs sdr"? Hybrids to hybrids, as they are neither pure analogs, nor pure sdrs? :) Comparing the performance , independently of technology, IMO, is the only way to get more or less objective picture of the radio and it also helps a customer to make a choice between the technologies. Like, I see nothing wrong in comparing , for example, the performance of digital filters in my FT-710 to a crystal filters in my Elecraft K3. They, obviously, are incomparable by their nature , but they both do the same job- digging out for me these weak signals out of the noise, so I can hear the difference, if any , and I can make a comparison. Analogy in the automotive world, for better understanding, would be a perfectly legal comparison between the mileage on one charge of an EV car and the mileage on one petrol tank of an Internal Combustion car.

Thank you very much Robert! I don't use the capacity hat in this video. If you are asking about the capacity hat to the AX-1 antenna in order to use this antenna with IC-705 and other tunerless radios, it's in this video: kzfaq.info/get/bejne/iatieNeH3J_QmKM.htmlsi=sqYEAaVFWf8jHUEW My answer to a similar question is in the comments section there: "One rule of thumb reads that the capacity hat electrically lengthens the antenna 2 or 3 times its diameter. It's like, the hat 10cm in diameter should lengthen the electrical length of the antenna by 20-30 cm. In my case, 1 needed to electrically lengthen my whip for 40 "electrical" centimeters (from resonance at ~15.3 Mhz, calcualted electrical length of 1/4 quarter wavelength ~ 466cm, to the wanted resonance at 14.1 MhZ, calc 1/4 wI ~ 506 cm. 506-466=40.). So l chose the diameter of the cap ~20cm, which turned to be pretty much in tact. But again, the size/geometry of the hat is not critical, it gives a big room for experimenting. " Hope, this helps. 73! Linas LY2H

Hello Angus Macgyver ! You can be inventive and do whatever you want to :). The log within the FT8CN just offers you a way to organize your log. You can mark the contact as "confirmed" manually by just sliding it left (not right, unless you want to delete the contact). This might be practical if you use paper QSLs and want to mark every single new contact confirmed in the FT8CN log. Alternatively, you can export all the contacts to a file, upload all these qsos to a LoTW ( or wherever else), get them confirmed by the service and then import them back into the FT8CN after which these contacts should turn into green "confirmed". In theory :), as I don't use this option, because I export all my logs from different devices into one big file in some other logger and then send in one piece to the LoTW. HTH, 73! Linas LY2H
