    I just got off the rig a few minutes ago after joining a roundtable on 80/75 meter bands. Yes, there were discussing politics, Covid-10, conspiracies and all, but in a civilized fashion. I was the "new" guy, and quite frankly felt welcomed when they learned I was just as conservative as they were!

    80 m is s great band I only run at 50w using a end fed half wave in a inverted U , I often work states up on 3790 or there abouts it’s the only band I know where I could be working someone 5 miles away whilst also some one in USA I also have most success in calling cq on 80

    80 meters is perfect for my area. There are mountains all over and my signal shoots up and bounces back down on the other side of the ranges. My first contact on this band was actually during the day and was about 300 to 400 miles away. I was using a mobile antenna and was in a narrow mountain valley. I was able to talk for about ten minutes until it started to get pretty noisy. I was blown away by how clear the signal was. I thought it was coming from a nearby town at first. When the conditions are good i can talk to people all over the state (Alaska) with 100 watts on my car mounted antenna.

    I really appreciate this series on the bands. I have been an on and off again operator for several years and have learned much. I agree that 80 can be fun but there are some really uncouth operators for sure. I sometimes wonder how they get away with the language and intentional interference they use on other operators..

    This is a great series and a channel I really enjoy. I am an Electrical Engineer but just passed my Technician and General at the end of the year. I am still considering what to do and where to start in ham radio. I have been interested as a kid since the '80s, but I never dug in enough to get licensed until I started following podcasts and KZread channels. I have really enjoyed hearing your thoughts and recommendations on QRP gear, antennas and digital modes. There is so much to explore and study here that it is really helpful to see some down to earth practical advice and how-to guides. You have some great resources for new hams and these don't require a lot of electronics background. They key is to get started learning and experimenting and just enjoy the journey. You do a nice job conveying how much fun this can be. Keep up the good work!

    Made my first contact on 75m when I got my general license. Guys had a roundtable going, they all meet on the same frequency every night,and we were very warm and welcoming. But I have heard the bad side on the Band ,sounds like anything goes.lol

    Antenna.... 130ft dipole with 600-ohm ladder line with a link coupled tuner (Johnson Match Box) is the best, most flexible antenna for 75/80. Ladder line is 14 gauge wire spaced 4 inches. Old school but it works!

    My first contact on HF was on 80m QRP with a long wire flung up a tree, while camping. Lots of contacts to be made on this band local (zl4**) and over the Tasman (vk4) after dark any time of the year on 5 watts. Power isn’t everything. Thanks for the well presented video. 73 ZL4KRS

    Something to note for people interested in listening, but not talking very far. For people with limited space, DXEngineering has plans for a 40/80m NVIS which worked great, easy antenna to build to get you on the air on those bands. No DXing that way, but very interesting, and able to start using the band and listen to more than you can talk to. Another great video, Eric. I am hoping to hear about the 630M and the 2200m. They are new to us, and would be very interested on a more laymans explanation. As always, looking forward to your next video. KY3M.

    The wavelength at 4.000 MHz is at 75m while 3.500 MHz is at 80m. Under the old band plan, the voice segment was from 3.750-4.000 (75m) MHz while C/W and Data starts from 3.750-3.500 MHz (80m).

    I put up a windom ocf about 2 years ago. Most of my hf work was at 3.845 and I fought with high SWR for most of those two years. Finally I shortened the longer lead by about 5 feet. Now I don't have to use a tuner! I know doing that changed the center freq's of the other bands it "used" to cover, but I'm not too worried about it, yet! How about doing a bazooka build, giving formulas and real world experience? KF5AQF Jim

    Lot's of OG's running a ton on 80/75. It's not too bad here in NorCal. I've made a few contacts to Oregon and Washington, but, yeah. It's mostly the good ole boys club. I prefer 40. Gettin my computer set up now so I can go CW or digital modes on the lower end.

    I've been a Ham since Oct and made my first HF QSO on 80m. Or was it 75M? I didn't Log it. So great video and looking forward to seeing the videos on the other bands. I've been working the others as well, lately 20m mostly, DXing and some nets and just some rag chews. A little of everything, having a lot of fun. The different bands do seem to have their own culture sort of speak. Greta Job, thank you.

    From what I have heard myself on “75 meters” at least it is FULL of a late evening and late into the night. It is full of legal limit signals and like you said, older operators who have the “us 4 and no more” mindset. It is good for local and regional operations as it uses ground wave propagation mostly. I have personally heard 11 meter type of operations and have been tarred and feathered and run out of certain groups. There are also certain groups on there that are quite welcoming. You just have to pick and choose which ones you try to partake in. It is a noisy band. I’ve tried tuning 80 & 75 both on the 75 meter resonator mounted on the bed of my truck and it just will not tune. It could be a faulty resonator or grounding isn’t good. I’m not sure which. Anyhow just giving stating my observations on the band. 73 Carl KB9HPM

    Glad ur doing this, it’s helpful for me. Does the receiver ( listener) which is me for now, need the same length antenna for 17 Meter 20Meter to listen? Is this why nice $40 radios with sw come with 25’ long wire?

    Thanks for the 80/75 info. This is KK4VTC up in Havana, FL. My antenna is a ZS6BKW . It works 3.5 to almost 3.8 mhz. So, what antenna is capable of working all of 80/75 or at least the upper end of the band? Thanks...

    It's a very reliable nighttime band...but the antenna requirements...unless I piss off my neighbours off, I don't think I'd ever realistically be on this band.

    The people that exhibit poor behavior on 75/80 tend to exhibit poor behavior on every band they use, so it's not like 75/80 is any worse than any other. For every dirtbag, there are twenty great guys who are happy to talk. I've yet to hear a net that isn't inviting new people every night. Personally, I love 75, and it's my escape from all the idiots on the local vhf/uhf repeaters. My first HF QSO was on 160, so I see your efforts to dissuade people from playing with the more challenging bands as a disservice.
