    Home duplexer / notch filter tuning

    Pardon me but I was not trying to "hijack the thread", I was simply asking about tuning a duplexer that came in the desk top package of a Motorola Radius repeater. The total bandwith of the device I was using covers 144-174. If it had been a 70c (440) machine I wouldn't have needed to retune it...

    Home duplexer / notch filter tuning

    I have tried to put a GR-1225 Motorola Radius unit on within the allotted spectrum using the usual split of 600 kHz and it won't work with the supplied duplexer. I have been told the duplexer supplied with this unit is good for a maximum 3 mHz spread and is better suited to 5 mHz. When I got...

    Who in the club has a D-Star radio?

    I just signed up and have that capability. The next question is what are the frequencies along with any necessary tones to access the repeaters for this group? I live in Claremont and Sunset Ridge as well as a number of other spots are accessible to me. KG6ABF Scott

    Entry Level HF Rig

    I would agree the IC-7000 is head and shoulders above the others mentioned. The fact it has VHF and UHF is a bonus and I can tell you you will be glad to have it when the situation arises that you need those bands and don't have access to your other rigs. I own the FT-857D, it is a great...

    Ic-7000 power level

    Here: Download Details That is the link to the download of the manual for the rig. It used to be the practice when a Ham got a new rig or a new to him rig, the first you did was READ THE MANUAL several times while going over the rig to (gasp) familiarize yourself with your new toy. Of course...

    Help me pick a radio

    Just curious since you mentioned the lingering smoke odor as a major reason you didn't like the rig and then added the DSP didn't work as the secondary reason you were returning the rig, did you ever sit down and really work the rig with a thorough understanding of the manual? I owned a field...

    Ameritron AL-80B

    I have an AL-80B. Running it on 240v, I see it hit peaks over 1kw. I don't use the alc cable but turn down the radio's drive into it to only the minimum it needs to key it and allow the audio to drive the amp. IF you set your modulation vi mic gain and processor/compressor to maintain the level...
