    Has anyone had bad luck with BT-9 and BT-32 alkaline battery packs for models like the TH-79A? I recently received two of each, and they appear to be junk. The are made in China, but that appears to be the only models that are available. The BT-32 packs don't want to close once batteries are installed, and neither one will power up the radio. The BT-9, 4 battery, packs close better but of the two I have only one works, and that is sporadic. I'm really surprised to see such poor quality.

    I'm starting the journey into amatuer radio kind of late in life but the first step - studying for the tech license - is somewhat overwhelming. I spent 20 years with one of the major wireless carriers, but I was mostly a real estate guy with occasional forays into the regulatory arena and special project. Despite being involved in building hundreds of cell sites, I still know very little about HAM, GMRS, etc. I should have hung out with the RF guys more often. :ambivalence: Looking forward to learning and growing. My primary motivation is alternate communication. I know first hand how fragile wireless phone networks can be. Kevin

    Here is the wiki explanation, it says the bandwidth necessary is 50Hz, whereas a CW could, theoretically, be narrower at 1Hz. I have personally not used WSPR, but it looks like a system like RTTY with the advantage of "in-between" tones, allowing for more throughput. Actually producing the tones can be done several ways, all requiring a stable timebase. You could modify the transmitter frequency of a continuous wave to give the FSK, or, more commonly, send different tones to an SSB transmitter.

    KVS - If you can find a used Ramsey FM stereo transmitter on eBay or wherever, and it's in working condition, that might fill the bill. I built one WAY back when Ramsey sold the kits, warning the user that the output was greater than ten mW, or 100 mW. One thousand milliwatts! I found a nice wide spot on FM that wasn't being used, connected my 2m/70cm antenna and played "Carmina Burana" while I drove in a radius of about half a mile from my house. Not a problem at all. Then I put it away. Still toy with it now and then.

    Apostolic ;). We are able to have in person services here, it is more of a communication need than anything. I was looking at the low power fm transmitters recently considering a mini drive in theater. Give people something to do at least.

    What do you do on the VHF bands? I'm a new licensee, and haven't really thought of anything to do with my license yet.

    Hi, I recently learnt a bit about WSPR, and it's very narrow bandwidth. I wondered why, as CW has less information than the short sentence used in WSPR does it need such a wide bandwidth, compared to WSPR. I understand that WSPR is sent at intervals, where CW needs to be live or as near to live as possible. When I'm thinking, I prefer to be uninformed, so as not to be too biased. so far I know that WSPR send a short sentence of location, callsign etc and CW has Dots Dashes and spaces. I've seen an image of what a WSPR signal looks like and would like to know how the varying wave is produced, in as simple way as possible please. C.

    Hi from Nottingham UK Gary. Notice that you have a vanity call sign. Sadly, in UK we are stuck with the call signs that we are issued with for life. It's like a breath of fresh air to see an experienced ham posting in this section. It's mostly guys looking for the easiest way to get a ham licence. Your novice exams are now so simple that 5yr olds are passing them. Yet l still see full grown adults looking for an easier option to obtain a ham license. Talking about exams. All schools & college students in UK had their grades "estimated" due to this virus. Ofcourse they are all complaining that the grades are too low. Many have now been retracted for review. So now in UK we have the great qualification giveaway. Ham exams can be done online. Therefore why can't these school exams be done online?

    Churches in this area use VLP (very low power) broadcast band FM in the church parking lot on Sundays. They seem to do pretty well. Apostolic or apocalyptic, though?

    I did not give background, my apologies and thanks for bringing that up. Current is vhf, if it was licensed at one point it has possibly lapsed, or it was not known a license was needed. I have done some digging to try to find out to no avail. I was able to contact the company the original radios were purchased from and obtain frequencies and tones. I need to remember to see where it falls in the band chart<this is a note to myself < MURS is something Iíve considered, but thought the same that if there is a license, there is no point in foregoing that. I love the point about inter-vehicle communication and had not considered that. Iíd only considered other venues. Thank you Brandon.

    Apologies for the lengthy story, this one is for people professionally acquainted with cellular sites... I recently went camping with the family, and of course, a few people really needed their internet. There is no signal in the hole this campground sits in. Anyhow, I knew the signal was really good up the hill 100 yards from the camp site so I took my fishing pole and a hookless spoon and casted a line over a high tree branch and taped the phone to the lure to raise it up in the air 30 feet. Suddenly, "tree wifi" was up and running well. This started a whole new project... I have known about passive repeaters (yes, i know, not repeaters at all) for years. The thought was to take my old aluminum 10m 5/8 vertical, run a coax through the center, and add a directional antenna to the top and bottom such that it can be stuck into a truck box pocket and used to fill in the camp site with signal. Everything sounded good until theory turned to doing it. Ive been doing some research into how cell sites work...

    Hi everyone. My name is Gary and I've been involved with amateur radio for around 50 years now. I enjoy VHF operations the most, but am somewhat active on HF also. I have mostly Kenwood radios, HF, VHF and UHF. Have also accumulated quite a few Motorola mobile and HT radios. I'm looking forward to using this site and forums on a regular basis. Gary / WA7IEP

    I would ask if their current radios are licensed as abandoning an active license would seem unwise. What frequency do they currently run on VHF, a MURS color dot one or something licensed? Id also be curious if there will be mobile radios set up for the vans used on away events. I know the church I used to go to took trips. I recall once going skiing with the church. Also, if you intend to go with a MURS frequency moving forward, i would spend some time monitoring the frequencies for activity (is there a walmart nearby?)

    KD9KVS started a thread Church Radio Set in Non-Ham Radio
    This is not specific to ham radio, but I am assisting the church with their radio endeavor. Weíve used vhf radios since I can remember and they work well. That being said, they are discussing adding to the set, with a possibility of replacing them all. The questions I have for them so far are... ...aside from being able to communicate across the campus will these be used elsewhere for outreach or events (distance). ...how important is security (others not being able to listen in without some knowledge of radio operations) I am thinking dmr/800 or 900 MHz if it is. ...Do they want independent operations or is WiFi operation okay, if so maybe an app like Zello. ...price they are willing to spend on the system set into place.

    Hi John, Have you tried hard reset the transceiver? If that does not help, I think it will remain to take the radio to an authorized Yaesu service center. This is a very unusual symptom. I had the ft-857d and ft-897d and never experienced a similar problem.

    Serious as a heart attack. I have newer operating systems, but full dos operation is required to use the C.A.T. On the 757. I love the rig, and prefer solid state over digital personally. I have seen some cool things about digital, but I cannot afford to upgrade. The 757 was a gift from someone who Repairís wwii radios and wanted his shelf space back. I like to use what I have and keep it in good repair rather than upgrade and spend money I donít have. I have the emulators for my newer machines, and may wind up using that to start, but I like the feel of the old machines. May seem odd to some, itís just me :). Thank you for responding.

The one thing I was unsure on about the cards, is I could not remember if the software was on the cards or how they operated. I suppose google probably has the answer, but Iím more of a hands on, letís communicate guy. Thank you.

    I would take the hard drive out of the 3.1 system and temporarily connect it to the XP system via IDE cable just like the XP systems HDD and use XP OS to copy the files to the other HDD then reinstall the HDD in the 3.1 computer. If the XP system uses SATA instead of IDE (which i doubt), you can find a usb to IDE controller used with older external hard drives to do the same job.

    You could try laplink if your XP machine has a serial port, transfer the files over that way, otherwise, try an ethernet PCMCIA card?

    Big step for me using C.A.T. To control my rig. The problem that I am having is getting the information from windows xp format floppy, onto my ibm windows 3.1 laptop. I cannot seem to get the information to transfer either way to operate. The serial port works on both machines, but terminal is missing off of the windows 3.1 laptop. Does anyone have any ideas for me on this? I donít want to run it through an emulator, but an original machine. It is an original 3.1 ibm, no usb, no Ethernet, does have pcmi slots, but getting the software on 3.5 floppy to run that does not seem a possibility. Thank you.

    I am hearing them at 6-7 years old on the repeaters here. They are knowledgeable about the hobby and seem to be having fun. I think the younger generation is beginning to be drawn in. Iím 32 and was to busy before I became disabled. Now memory is an issue of course, but I have to study hard and work for it. If you look online many schools are doing ham radio programs beyond talking to iss. Hope this gives you some hope.

    Good evening. After about three months after passing My foundation exam, it seems to Me that the hobby is full of over 40. (I Myself is a young 61),I may be wrong. My question is how will the hobby attract young/younger members?. All the contacts I have spoken to are late 40s on wards. How do clubs or RSGB plan to address this situation?. Also in all My contacts, none were female so far. Do the general public know what armature radio is all about? True that the practical part of the exam has been stopped or put on ice, but a exam has to be taken. I think that the radio hobby should publicized or more approachable. How many carry a handheld in the street, the only radio the public see in a store is a security guards, with a ear plug in. I have walked through shopping centre with a handheld on, quietly, and asdas. If We are licenced, we can do this legally. Any coments welcome. M7ATX

    Since getting back into radio last year when I got Yaesu FT-991A and selling my old FT-897 I've been using 2M0SQL (Admin on here too) online logger called Cloudlog. If you run own Server running PHP & MySQL can setup for free or can have a low cost hosted solution from him. Visit http://cloudlog.co.uk to download the software. So many features, but the one I like is I can use on any Device (I've even tested on a e-Ink Kindle), can connect to some radios, and is actively updated, has features for managing satellite contacts, award tracking, QSL management, and more.
