Suspect Operator error The Dosy FC-50 is a direct reading freq counter, as such, a poor swr or higher reflect will throw off readings or make it impossible to read the tx freq. Try using a dummy load and it will read. Insertion loss is negligible and so is impedance disruption at HF bands. I...

The Dosy's are not mass made by machine like you think, and they are calibrated. Components are manufactured, circuit boards are soldered either by hand or by waveline, but I doubt they use full robotic automation in their plant, as I see that at least 10% of the meter to be hand soldered...

calibration and Dosy quality Sorry to hear of your experience with your Dosy. Curious, you mentioned that you had your Palstar calibrated prior to shipping to you, did you consider having your Dosy calibrated prior to using? It may have fallen out of Cal in rough shipping. This is all to...

Peak reading vs RMS, Dosy vs. Bird As have been said before, a Bird without a peak reading kit will read like a Dosy 4000 series set on RMS and the Dosy can be calibrated to the Bird or to any other RMS measuring standard. A Dosy set to peak reading mode will read about 70% of true PEP (when...

Looks good and integrated with that Bigfoot Looks good and integrated with that Bigfoot but I intend to mount my Dosy FC50S sideband capable freq counter centered on the top cover of my TC-4002-PSW-V when I get it. I do have another brand new Dosy of the same model that i might setup with...

watch out the Diamond meters cannot handle full rating for long- ParaDynamics better watch out the Diamond meters cannot handle full rating for long, read the instructions, duty cycle info it quite limiting- ParaDynamics and the recent Astatic 600 have heavy duty line sections that do the job...

I agree, I have two TC-4002-PSW-V from him, both perfect I agree, I have two latest design December 2011 production TC-4002-PSW-V from him, both perfect functioning and calibrated. After dealing with second hand abused meters, I decided to get what I always wanted, a top of the range Dosy and...

BTW, the calibration pots are labled on the board in the Astatic 600 BTW, the calibration pots are labled on the board in the Astatic 600. On one board are pots for each calibration power setting 4x. On the other board is the modulation adjustment, I presume as it is not marked. This meter...

For general system monitoring the Dosy cannot be beat for the price. It is mechanically durable, easy to read, ranges fitting most station power levels, and has features that aid not only in antenna health monitoring but it will also help adjust modulation setting over the air, especially if...

So much misinformation on the web.. Dosy are calibrat-able meters So much misinformation on the web.. Dosy TR-1000 as well as the other meters in their line are calibrat-able meters. The TR-1000 can be calibrated to another standard if needed. The Dosy professional architecture meters are not...

Audio check using Dosy audio monitoring function The final check is always with the on-air audio. The Dosy 4001 and 4002 P versions have an audio monitoring function that will allow you to hear the quality of the audio peaks. You can calibrate your meter according to the audio quality. Quite...

I just read up on this thread, thanks... I just read up on this thread, thanks for the continued input plots showing top hats, Marconi. I for one have just compared my originally 80" MM antenna to a modified version that I made and have found no discernable difference in signal in a two mile...

Excellent, thanks! Excellent, thanks!

Has anyone of you experienced performance equal to or exceeding 9 foot whip on 11m using the same mounting vehicle setup but with a vertically challenged antenna? Wouldn't it be nice to somehow exceed the range of the 9 foot whip in less vertical footprint? It may sound like a pipe dream but...

My own antenna incorporating efficient loading. Measures only 50 inches tuned on my vehicle. Does very good compared with my Francis CB50, no noticeable difference on the local scene. Same tx rx capability reports compared with my whips. Like the 55 Immortal but a little longer, smaller cap...

CP antennas are required when orientation of antennas vary Old topic, so if anyone is interested. CP antennas are required when orientation of antennas vary as in satellite to land based antennas, i.e. GPS, etc. Because there is tremendous difference in gain when polarization between antennas...

Not so important how it looks under a microscope Not so important how it looks under a microscope. What is more important is how structurally sound and durable it is and its actual performance. I was told by Charger that those antennas are made of 6061 aluminum, that is among the best around...

There's some magic to this cap hat thingy, but I don't have time to get into it There's some magic to this cap hat thingy, but I don't have time to get into it right now. If I could afford it I'd love to give the Immortal some key time. I use a Monkey made long shaft MM7 with MM capacitance...

Critique on Immortal Antenna ingenuity, no doubt. It is a double loaded design with capacitance top hat for additional physical height reduction. The sheer thickness of top hat and top mast components ensure good signal handling from surface area which thin antennas cannot match. The top...
