It can be a challenge to find antenna configurations where the MFJ-1026 actually improves the radio listening experience. The first few days of trying the device seemed transparent and switching it ON or OFF did not make any difference to the radio. Neither did any of the settings of the front panel dials change the signal at all. I tried a wire antenna as MAIN and the MFJ whip as AUX,  the wire as AUX and one of the GRAHN loop antennas as MAIN, both GRAHN's next to each other on the desk, a GRAHN away from the radio and the whip as AUX. None of that nor any dial combo made a difference and it seemed the MFJ-1026 was transparent / indifferent.
Now I found one configuration that works on a frequency that I tried.
Both GRAHN antennas are somewhat distant from the radio. One is on MAIN and one on AUX of the MFJ-1026. While alternatively dialing MAIN and AUX to the max exclusively, I tweaked the direction and toggle options of the GRAHN antennas to each their optimal signal. Next I used them both and used their dials on the MFJ-106 to have them deliver an equally strong signal. Next I turned the PHASE dial and it turned out the most clockwise position had least noise.
Next, switching the MFJ-1026 to the OFF position (this feeds the MAIN antenna direct to the iCOM IC-R8600 radio) delivered a noisy signal as can be heard after a second or two. Switching the MFJ-1026 back ON considerably improved the signal as can be heard after a second or two.
Still, the most significant 'cleanup' of sound is done by activating the little bhi DSP device ;-)

Finished Pavoni & Fuji PXG4 pid: Probe Inside the Ring

Delicious cup: all the work was well invested! At the end of the previous blog about the pressostat and PID working together , I mentioned that I would like to clean up the xmas tree of wires and have as few cables and probes as possible to visually disturb the classic design of the La Pavoni. Getting rid of the probe that was fastened with copper tape to the top of the brew group was a priority. I wanted to hide a new probe in the cooling fin as close as possible to the brew group. This morning I asked Tije if he could do that. He would need to drill a straight hole of 3mm diameter in the 4mm inner ring of the cooling fin that sits as a tight clamp around the brew group. Always the optimist, Tije set to work: First, Tije made a piece of aluminum to fit the inside of the ring. Drilling a thin hole straight through the curved aluminum, if possible tangentially going through the inside of the ring to touch the brew head directly, you need the support of the temporary insid

Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics.  On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan

KiwiSDR2 [radio]

  Despite selling one and giving away two of the five monster vintage 'boat anchor' receivers that I had, I still enjoy listening to shartwave radio. The modern iCOM R8600 that I also have has a wider range plus some decoding options but it's not easy to figure out what encoding is used on which frequencies. The SDR-Control app from Marcus Roskosch at https://ham-radio-apps.com/ makes this much easier and also allows some remote control of the receiver so you can place it and an antenna at the top floor of your house while listening downstairs. I also got the SDRplay RSP1B box: This offers a great listening experience at a very low price compared to the iCOM hardware. I had one before and bought one again after a (somewhat limited) Mac version of the software became available. This device needs a computer to be connected to the receiver. For some time now a nifty little device has appeared which not only works standalone, it even allows you or anyone else to utilize the
