    ST2 Scantenna tested with NanoVNA

    Which 50 to 75 Ohm resistive matching pad did you buy or build? The one I linked with SMA male to F female, or something else? That will tell us all if an adapter is needed. From your note, it seems like you are trying to take a shortcut and not include the 50 to 75 Ohm matching pad. I could be...

    ST2 Scantenna tested with NanoVNA

    Thank you for sharing that professional cost to keep things in perspective. Still, these low cost VNA's are reasonably useful, but always knowing the results may be incorrect. Fortunately, that lesson only cost me $40 in microfarad capacitors, time, emails and probably lots of head shaking by...

    ST2 Scantenna tested with NanoVNA

    Yes definitely and thank you for pointing that out. I should have noted that and not assumed performing a calibration was understood step after attaching the pad. I thought it was already mentioned in this thread, but reminders are good. I would never use a 50 Ohm VNA with 75 Ohm coax connected...

    ST2 Scantenna tested with NanoVNA

    Exactly - I have connected a VNA to my 75 Ohm coax which is connected to the ST2 300/75 Ohm transformer and the results were a mess due to the mismatch of using a 50 Ohm VNA. A search provided this matching pad, but I am unfamiliar with it. There could he others for more/less. Are you already...

    ST2 Scantenna tested with NanoVNA

    If you are using 50 Ohm coaxial cable to your AT197, connect your VNA to that and see what should be a normal plot. The result should not look erratic. Set your VNA to look at 200-500 Mhz. (I use LMR-400 with my AT197) I have connected a VNA to 75 Ohm coax to my ST2 and the result was an...

    Recomendations for legally learning and training on motorola RSS/CPS

    For me, an APX is a wonderful tool and I use P25 quite often. My other newer ham handhelds (Yaesu FT3 & Kenwood D74A) have only recently caught up with some of the features it offers. I definitely do not think my VHF/UHF 7000xe sucks. Like most things once you get used to programming it, and...

    Icom: IC-705: New QRP rig from Icom in the works

    I found some Japanese vendors selling the IC-705 for $1100, but I also found a few others that are selling it for around $1070 and that is with tax included. Whether we see USA vendors selling it for sub $1000 ($975 +tax) right off is an unknown. I hope so as I plan to get a 20 Ah LiFePO4...

    ST2 Scantenna tested with NanoVNA

    I agree that the ST2 performs better than various discones I tested in the frequency ranges it advertises. (30-50, 148-174, 440-470, 470-512, 800-912) If one enjoys 118 - 144 MHz for civil/mil aircraft, or 225 - 400 MHz for military aircraft, a discone wins. Well, at least in my testing and...

    You and or several others could be the coordinators for your region or state. The authority is derived from the amateurs in that area. It's just us amateurs agreeing to have others coordinate. If one creates, maintains and coordinates an updated list that would be a good start. Reaching out to...

    Could anyone help ID this antenna?

    Those panels are aimed at the horizon. I was thinking it may be a Ham omni mesh antenna. If so I am not familiar with that design. To the OP, does your neighbor have any other antennas on their roof or vehicle? Could this be a someone’s idea of a digital TV antenna? I have seen some weird thngs.

    Repeater coordinators are volunteers. Testing repeaters constantly to ensure they’re working is to much to ask due to time, distance or whatever reason. It is the responsibility of the repeater trustee to contact their coordinating body and advise of changes. Still, the trustee can become an SK...

    I am surprised you do not have the antenna launcher upgrade, so you can get that "wire" up high and work some DX.

    Recomendations for legally learning and training on motorola RSS/CPS

    Agreed on the 2 meter FM. I use a VHF/UHF APX 7000xe but rarely use it for FM, as we have plenty of P25 repeaters in my area. Is the 7000xe brutally expensive, hell yeah. It was given to me though. Still, I have purchased an XTL5000 for under $500 and 3000 & 5000 XTS FPP handhelds both with...

    R30 Squelch on HF USB?

    Thank you for the clarity with the performance examples of the R8600. This would be acceptable to me. I would just prefer to have that in the R30 and save a bunch, as well as the portability. I have other stuff I do not need in my immediate purchase future (IC-705), so I'll need to call K-Mart...

    Question on Ham Digital modes.

    1. First and foremost analog is king. If you have an analog radio now you're fine. You'll catch more people on analog. 2. As for traveling and digital modes, Yaesu Fusion is quite easy to program on the fly. Just enter in the frequency and hit a button to select the digital mode. The offset is...
