Since you didn't get one you need to call MFJ and tell them it was missing and they will send you one free of charge. Their catalog states they come with the jumper block but the ones in the stores are missing them. This kind and size of wire was commonly used for household telephone wiring and Ethernet wiring found in some homes. If you are good at DIY, you can use ga insulated solid copper wire for the jumpers. Actually on the bottom of the top board, so you have to remove the 2 screws that attach it, turn it over, and you will see the socket for the jumper block. Oh well, project on hold until I get this jumper block if they mail it to me. It is suppose to come with the cable but some old stock in the stores are missing the cable.Ĭould you clarify this? The Tech I was able to reach seemed somewhat familiar with this but stated it should be there. This mistake is repeated every time that either jack is shown in the manual.From: RigPi groups. This jack has been added directly next to the Receive Antenna Connector.īoth are phono RCA jacks.

The PRO appears to have more available microphone input gain, and I can drive it fully with both dynamic and electret condenser elements. I had to use an electret condenser element or a dynamic element with a pre-amp.

With theI found it difficult to drive the transmitter to full output with a dynamic microphone element. I have written about ICOM radios and microphones on another page. Since I made my first comparisons, I have made a closer look at the S Meter. The meter readings are not the result of analog signals changing, they are the result of a numeric computation. The meter itself, which reports several different qualities, is driven from a microprocessor. The S meter on the seems to follow syllables in words, and the dits and dahs of CW.įinally, there appears to be no adjustment on either radio for S meter calibration. Their S meters indicated the same strength for the same test signal. On the other bands, the two radios basically tracked. The difference was about 5 dB on 40 and 15 meters, again the reported a higher value. The mismatch was the greatest on 20 meters, where the read the same signal as 8 dB stronger on its meter. I also found what I call a tracking difference between the two radios. The difference between S1 and S2 may be as little as one decibel or two.
Below S8, both meters becomes increasingly more sensitive. On both radios, the difference between S8 and S9 appears to be 6 dB, a typical value.Ībove S9, the meter readings are fairly accurate, which is to say that meter markings track real relative decibel changes. Still, they are all we have to measure signals, and they are often quoted. S meters are not calibrated against an absolute signal strength reference. I think we have all learned that S meters are, at best, relative signal strength indicators. So, for me, spending the extra money made sense. On top of that, there is the color display and a number of other enhancements.
Contesting on the IC-756 Proīut if there were more slots, it seems as if I would need to add 6 or so filters to be able to get the SSB and CW selectivity choices I would like. Of course this is not even possible because the has a single filter slot at each IF frequency.

Ajpw hacksįor me, I decided that the upgrade cost made sense because of the equivalent cost of the filters necessary to turn a into a PRO. In fact, given the cost difference between the two radios, I think that both are well worth their respective prices. I really do not want to give the impression that either radio is bad. Because I am comparing two radios here, it may appear as if one is good and one is bad. A few of my observations are contained at the end of this page. The ghost and the darkness netflixĪs of this writing, the radio is still quite new, and comments and observations are just starting to emerge. If you have any of your own observations, please email me, and I will add them to the list if appropriate. This gave me an opportunity to compare both radios side-by-side.
