Having a problem getting the baby loop to tune in 10mtrs.

It trys to tune but blue light is flashing to suggest motor is ok but refuses to tune to selected frequency,any suggestions?

I too have had the same problem since installing the antenna over a year ago - I have tried repositioning the loop and altering the height as suggested by Ciro Mazzoni - any other suggestions would be gratefully received.

Same here Brian,itwas tuning ok till a few weeks ago,i put a new ratator on and it increased the height about 12 ins,so dont know if that had anything to do with it or not.When it was at 1.5 mtrs all was well so when i get the time i will lower it and hope for the best.I can get it to tune if i select increments of no more than 50 Khz.

I am not sure there is an off the peg solution - I am still waiting many months on for a suitable reply :(

Hi Brian,think i have solved the problem with mine.

I only switch the internal atu off on the switch on the front panel of the radio,so having a mess about yesterday i went into the radios menu and disabled the atu from there,since do that i have not had a problem tuning the loop on 10mtrs.

Hope this helps.

That would do it :)

Hi, I am also experiencing the same problem. After replacing a faulty actuator the antenna will no longer tune above about 26MHz. There were no installation or alignment instructions, and I was left to use 'trial and error' to get it to work. On the bench I found that the actuator has built-in limit switches. I set it to the inner limit and mounted it on the antenna, and fully closed the loop before tightening the mountings. Then I measured the resonant frequency with my AA-230Pro antenna analyser and carefully moved the mounting until the antenna was resonant at about 6MHz so as to ensure thatI I could reliably set the antenna to its 'parking' frequency of 6600kHz. Here in Cyprus at high temperatures in the summer the nylon mounting bars expand such that it was sometimes impossible to get the antenna to tune below about 6800kHz. When the actuator was set as described, it would then reliably tune to 6600kHz as well as reliably auto-detect using the controller, but still I am unable to tune above 26MHz. I have requested the installation and adjustment instructions, even if they are in Italian, but so far no reply. I should add that my actuator failed after water got in during the winter, and was replaced under the warranty by ML&S (UK) from whom it was purchased.

Adrian - Great news on the replacement part - Maybe (assuming Ciro Mazzoni monitor this page) we can get some clarification on what we can do to rectify these problems ??

I have now conducted some more tests. Ciro-Mazzoni were kind enough to send me their adjustment instructions. With the actuator mounted exactly in accordance with their instructions, with the antenna driven to its inner electrical limit, the resonant frequency was 6,355kHz. With the antenna driven to its outer electrical limit, the resonant frequency was 29,790kHz. As before, when attempting to tune to a frequency higher than about 27,000kHz, the controller would enter an infinite tuning cycle. For example, when attempting to tune to 28,000kHz the controller would display a frequency oscillating between 27,840kHz and 27,845kHz, but would never settle. The only way to stop it is either press and hold the Back Space button or turn the power off. As an experiment, I re-connected my old controller, the previous version, and it tunes the antenna over its entire frequency range apparently without a problem. So, I am of the opinion that there is a firmware bug in the new controller.

Adrian - Great work.

Can you send me the adjustment instructions?

Mine does exactly the same except mine will not tune above 26,000kHz.

Maybe there is a bug in the Firmware

Have you gone back to them with your findings ?

Hi, Brian, if you email me at: adrian04@cytanet.com.cy I will send you a ZIP file with the C-M adjustment instructions, as well as my SWR sweeps of all the amateur bands from 40m through 10m, as well as my other data related to this antenna.

Still not able to tune 10m!! - Is there any feedback or fix available from Ciro Mazzoni ????

Hi Guys

I have a problem i updated the firmware from 3.14 to 3.22 the latest firmware

Downloaded onto a usb stick loaded into the atu and tryed to setup again and all failed

cant tune the loop and when i try it keeps saying tuning fail no resonance

loop still in its same place no change

only had this problem since updating to the 3.22 firmware and ive even gone back to the 3.14 but still no joy

Waiting for Ciro to come back to me

Did Ciro get back to you? - If so what was the outcome ?

HI

Hi has anyone got the same problem as me when the wind is blowing the SWR bounces all over the place on your Rig. ???

brian

Mine has been up for 2 years now and I have not noticed the wind causing any problems.

Hi

my swr does bounce at times so maybe the wind but dont know why ?

My Baby Loop will no longer tune past 21 MHz. It just drives to the extreme limit and says "Motor Fail No Load". Any advice??

brian

It maybe a problem with the actuator not adjusting correctly... I've given up with trying to get my loop to tune on 10M - There is little or no support for the product here in the UK unless you are prepared to send control boxes back to the manufacturer which can take up to 6 weeks - Great product a huge price tag but lacks the comparable support.

Thanks, Brian. It sounds like maybe the limit switch for the higher side on the actuator, although others have commented about it not occurring until they upgraded to firmware V3.22. That's also what I have. You'd think for the price tag of the antenna they would address this issue. Thanks for your reply and if I hear more about it I will post it here.

Hi.. an EZNEC model suggests that the gain is maximum at antenna heights between 1.5 and 2.5 meters, which is probably the reason they say to mount it between those heights.  Looking at the maximum gain only, the gain difference between 2 meters and 10 meters height is about -2.7 dB on 40 meters.  However at the higher height the difference at low elevation angles isn't that high.  At 20 degrees elevation the gain is only down about 1.2 dB from the 2 meter height.  The antenna produces less high angle signal at the higher height.  I didn't look at the other bands.  Mounted on a roof it will be difficult to determine the height the antenna sees because what is inside the roof is probably unknown.
