The Cat5 ethernet cable that goes between the head unit and main radio for the D710 is kind of special. Here is a picture of it showing the cable. I'm pretty sure those are solid core wires.

I'm looking for something that might be easier to operate than XASTIR. I need to teach someone how to run a D710 with computer interface and there is too much hacking in the terminal for it to be very feasible. The software only needs to plot APRS packet GPS coordinates from a Kenwood D710...

I am looking for a logic high from inside a Yaesu FT-1900R when the radio decides to output audio. I have a complete paper circuit diagram, but can't find a .pdf one to share. The inside is really accessible and I have been able to poke around with a logic probe at various things. I have not...

Is Narrow/Wide FM a setting for the transmitter and the receiver, or just the receiver? What is the difference and what works better in different situations? tnx

I would like to run this by the WWRF expertise before I connect everything and break something... Wacom WP-637 Band-Reject Duplexer Two pics attached (before I tuned it) One datasheet One response curve graph 1. I thought I would measure the resistance across the center and outside of...

Are deep-cycle batteries good for backup power for radio gear? I figure going to Checker or Autozone and buying the biggest battery would be the best way to do this. Checker sells a very large $125 "regular" automotive battery and a medium sized $75 marine battery, but rated in "cold cranking...

Most all mobile radios have this specification for the transmitter maximum deviation, +/-5kHz. I want to find out the range of frequencies that a transmitter will cover in addition to the tuned frequency. What information in the datasheets says how much that deviation is at a given power output...

I have a question about who signs where on the club callsign form, here is the page that has a link to the form. ARRLWeb: Instructions for NCVEC Quick-Form 605 Application for Amateur Operator/Primary Station License Specifically There is a professor and student scenario. Would it be...

How easily is to to remove an antenna after it has been installed? I have a Diamond MR77 Diamond MR77 Dual Band Mobile Antenna and the antenna "wire" could be removed but the mag mount would have to be cut off if someone wanted to steal "the whole antenna". Most other antennas I have looked at...

Green Light Labs GPS-710 Found this, anyone have experience using this or another GPS for the D710? UR doesn't list one specifically, Kenwood TM-D710A TMD710 APRS Mobile Radio. From reading, it seems like a pretty standard GPS. Thanks jm

Recently I have been ranting about monoband/dualband HT antennas, to be honest the last antennas I have been looking at were for mobiles and I for some reason though that there were monoband HT's as well. There are quite a few monoband mobile antennas, but when I went back and checked there...

What is the difference between the squelch knob accessible on the front of a radio and the "S" or "RF" squelch that is in the menu? For example, the Yaesu FT-1900R has a squelch knob on the faceplate and an RF-squelch on menu item that goes from OFF to S9. Thanks!

How does a variable power supply work? I am thinking of the kind that have the knob to vary the current as well as the voltage. It is the current part I don't understand. I am imagining my HT radio that wants ~13.8 VDC, if I hook it up to a power supply that doesn't have the current knob it...

Is the 50W max transmit power on 2m, 1. 50W coming out of the radio or 2. 50W ERP coming out of the antenna?

pl tones 1. They are a continuos part of the transmission right? 2. They are sub-audible (low amplitude), but does that sub-audible tone go through the audio output (speaker) on the receiver? 3. I can test this by transmitting with a pl tone and have a receiver plugged into my computer (via...

The 8r has preprogrammed into it all of the marine band memories. You can access these by pushing "Function", then "SP Bank" secondary key, and finally hitting the "Band" key until you see the "INTVHF" memories. My question is, can these frequencies be transmitted on via this memory mode...

Just tried this. It is not possible to clone a MARS/CAP mod radio with a regular unmodified radio using Yaesu's CT-134 cloning cable. Regardless of what is programmed in memory of either radio. See VX-8R man pg 135. Yaesu VX-8r mod - first on the internet! Just did the mod to the second...
