    Never heard of anyone, ever, ID'ing a crossband radio. When you ID you are ID'ing both radios at the same time. I feel like KW has the feature for using the 71a as a stand alone crossband repeater, not for your application as a single user.

    All I did with the ones in my bedroom was install switches in the power cords for the lights. Eventually I'm going to rip the guts out of them and just make them into switch lights.

    Im just beginning down my electronics journey but id guess that a ferrite bead on the gate pin of the triac (likely a BT136 or similar device) would solve the issue. EDIT: This site makes other suggestions http://www.arrl.org/touch-lamp

    Here's a question for the circuit board designers. My wife loves our cheap chinese touch sensitive bedside lights. So do I, but the slightest whif of RF switches them on and off. So a CW contact has our bedroom window flashing like the bridge of a warship! I'm told that it's because the cheap chinese circuit boards have no filters. So, is there a designer out there who can design an easily built, small, circuit board that won't be so hellishly sensitive to rf but will still do the job of providing touch sensitivity to our lamps? I'm happy to experiment and build something, provided it won't blow us up!! Richard G4JJP

    MikeAlex replied to a thread Base Radios ICOM -725 - fault after storage in Icom
    Hi Brandon & Martin and thanks for the replies. I see my first two replies have now appeared. I can confirm that having the radio from new, from a reputable UK dealer it has not had a Mars mod performed. All the diodes check out okay in situ although I appreciate that is not necessarily the case under power. There's an awful lot of board connectors to disconnect before i can remove the PLL board to check out diodes by lifting one end.Guess now that is the next step. I'll check out your idea martin and look at the voltages at band edges. I wouldn't have thought that Icom would have programmed the microprocessor per region and I have come across diode matrix selction before but in this case everything is as per the schematic and basic in situ tests seem okay - hence the mystery. I had though about using it as a dedicated PSk31 or other digimodes unit as I have a Yaesu 450AT in use at present.

    K7KBN replied to a thread New Ham Here in Introduce yourself
    When I got my novice ticket back in 1959, I had NO HF voice privileges, and small chunks out of 80M, 40M and 15M for CW. Since I'd just passed a FIVE words per minute test, my first several thousand QSOs were on CW. Even though I got my Conditional* ticket in March of 1960 I stayed on CW: (1) It worked for me. (2) My transmitter was CW only, and crystal controlled. I upgraded to a Heathkit DX-100B which weighed as much as I did. Now I had a VFO and AM capability as well as CW. Digital was hardly a glimmer in most ham minds back then. Do a little operating on modes and bands your license allows. Get your feet wet by learning on the air, not from an "app". *The Conditional class license was administered by one volunteer examiner who had to be over 21 and had to hold a General or better. On a family vacation down near Los Angeles I visited the FCC office and got the Conditional changed to a General. Had to retake both the code and written tests, but I think I aced them both. The experience...

    Try not to worry about the missing posts. That same thing happened to me, when I first joined. My first 2 or 3 posts never happened. When you first join the group, your posts have to be vetted by the administrator. If it's OK, he/she should let it post. But apparently, that doesn't work too well. At first I read this as "735", rather than "725". I have a IC-735 and thought I could help. However, I did look around the internet. I couldn't find anything related to your problem. Except for that D5 modifications, there very little on the IC-725. You might want to check the voltages on that diode to see how they act when you go out of the band edges. On my IC-735, the diodes that restricted the radio to the ham bands were already removed when I got the radio. But I never let it bother me. Except for my early days as a Novice, when I was crystal controlled, I never let the radio tell me where I can go. I was always well aware of my band limitations. In the early 80s I spent several years in Germany,...

    Hi guys, Can anyone help? I'm replacing an old molex type connector on the power cord going from the Tentec power supply to the back of the Omni 6. I have to order it on the internet. It's a four pin molex connector that takes female pins. I'm concerned there might be a variety of 4 pin molex connectors out there with different pin sizes. So does anyone know the specs (or part number) for the molex connector so I can be sure I'm ordering the correct one with the correct female pin sizes? I've sent an email to Tentec but it was bounced back with no response. Thank you.

    Sounds like a mars cap mod was done to the radio at some time. I would take ICOM's advice and just watch your TX frequency if the radio works as is.

    Located at DM26. No call sign yet, taking Technician exam on March 7th. Confident that I will pass with no issues. Will update my user name when I get my call sign. Being a noob, I'm definitely going to be looking for knowledge and practical information on this forum. If I can't find answers to my questions online, I will definitely be asking them here. Hopefully, the "There is no stupid question" phrase reigns supreme here. Currently, I have an HT, 8watts (lol). Looking to get a couple RF power amplifiers (30-40watt output) and an antenna to set up a modest home station. Low power but, it's a start. The amps I'm looking at are also suitable for mobile so I can easily take one amp when I go off-roading, mainly for emergencies. Looking forward to an enjoyable experience here on HRF.

    MikeAlex replied to a thread Base Radios ICOM -725 - fault after storage in Icom
    I have replied to this thread a couple of times but nothing has been posted. I am using the 'reply to thread' button. My previous replies were based on the one reply I received and I responded that all the bands were available but that the span of the bands, with the exception of 160 M, was much broader than either regions 1,2 and 3. This suggested to me that whatever method Icom use to determine the appropriate coverage for each specific region had failed. I was hoping that somebody might be able to enlighten me in order that I can investigate further. Is, for example, the specific region programmed into the microprocessor or is it selected by some other means. Icom UK were unable to help but did suggest using it but keeping a close eye on band edges here in the UK. Any comments would be appreciated. Mike GM0OXS

    Greetings from western Montana. I just earned my Tech ticket and am studying for the General. A long...long time ago, when I was a kid, I loved using our old shortwave to listen to whatever I could find. Finding the GMT signal was even fun! Recently bought a Chinese HT and been listening while I learn about antennas, and radio in general. I plan to become involved in ARES; I'm interested in digital stuff but I want to be able to operate mobile and self-contained. It's obvious to me that understanding propagation better is something I need to do. I'm going to order an SWR meter and a 'better' antenna for that HT while I decide what next transceiver to get, and mess around with antennas a bit.

    Hello HRF! I live in KY, USA, and passed my Tech exam on 12/31 and wow, the whole process was a blast! Starting in November, I studied W4EEY's videos on YouTube and tested my knowledge with James Thomas' iPhone app called Ham Tech. I haven't ever enjoyed learning something as much as I enjoyed learning this topic. When I sat for my exam, I was pretty nervous but the hams at the EMS building were welcoming and encouraging. Now, I'm studying W4EEY's General Class videos, Buck's "Easy Way" book, and the General version of the same app for the iPhone. I could probably get by with one of these three things, but I usually listen to the videos when I'm driving, read the book when I'm at home, and fill in the gaps (and check my comprehension) with the questions on the iPhone app. I'm not sure exactly where to go after this. Hams- what did you do first after getting your ticket? What about when you got your General? Extra seems like a far-off dream for me, so I'm not sure what to even ask about that one. The...

    I think I miss worded about the ID freq. it will TX the ID on the freq that you are Xbanding, the ID will be retransmitted over the repeater, not the frequency that you would be using locally ( unfortunately ). “ Unless I want to duct tape and superglue a Diamond X200A antenna to my HT and drag around a ground rod with me wherever I go on my property.” You would be like Doug on the gieco commercial when they gave him the key to the city : )

    That's the first I've heard that some of the 71's could auto ID and some can't. Guess I would want to talk to Kenwood about that one. At least I know now that the auto ID only happens on the input signal. I still don't like the idea of it auto ID'ing on UHF all the time. Which would still probably be illegal, because if I walked away without shutting off the 71, then the 71 would be automatically transmitting without being under anyone's control. At least it wouldn't be auto ID'ing on the "in town" repeater input frequency all the time lol. That would be really bad! Sadly, I think no matter what, I'm going to be tethered by coax to the antenna on my roof. Unless I want to duct tape and superglue a Diamond X200A antenna to my HT and drag around a ground rod with me wherever I go on my property.
