After committing this configuration to my Yaesu the result was the full VHF / UHF range became unlocked while HF remained restricted.According to Yaesu's guide, Jumper pads 6,7,8 need to be CLOSED, 4,5,6 need to be OPEN, and 1,2,3 remain OPEN / unchanged. After committing this configuration to my Yaesu the result was the full VHF / UHF range became unlocked. As for HF... HF transmission was not completely opened, however, some placed did open up, some of the MARS specific locations and also some others, yet some MARS frequencies were still blocked. Citizen Band remained blocked. WWV was open to transmit! Weird.# 4041 ... no ... MARS# 7302 ... yes ... MARS# 7500 ... yes ... Military# 7540 ... no ... MARS# 7635 ... no ...

Citizen Band WidebanderV4.exeNote: This software does not work with the ND model, only the original ft-817. If you have the ft-817ND you will have to perform the hardware modification as described above.When using a USB FTDI programming cable:<BR>Using FT-817 WidebanderV4 was easy once Windows was forced to allow it on one of the lower comports. This software must have been designed for computers prior to the virtual COM port driver (VCP). You will not be able to use the software if once your FTDI data cable is using a VCP higher than com:6. Force it to com:6 [[Image:device-manager-vcp-com6.png]]<BR>Windows Key + R, type "devmgmt.exe" press enter. Look for Ports (COM&LPT) and find the USB Serial Port, right click, Properties, Por Settings tab, Advanced button, and set your com port. The software did not need to be "installed" as it ran directly from the exe file! This is good.With the FTDI cable connected place the radio in cloning mode. Do this by holding down BOTH mode buttons while turning the power on. You should see "CLONE MODE" on the display. Run WidebanderV4.exe and click the option in the "Wideband Radio Now" group "817." 1.8 Mhz - 33.0 Mhz 34.0 Mhz - 56.0 Mhz 140.0 Mhz - 154.0 Mhz 420.0 Mhz - 470.0 Mhz== Accessories ==There are many accessories for the ft-817. Some noteworthy accessories are mentioned here.===external display===[[File:ft817catdisplay.jpg|thumb|none|200px]]CatDisplay plugs into a Yaesu transceiver CAT port. It reads EEPROM data from the transceiver, detects & decodes any changes then updates the display. The custom algorithm also monitors transceiver use and slows down data requests when idle.CatDisplay reads information from the transceiver only. It does not write information to the transceiver and cannot be used to control the transceiver. Unlike computer programs that control the transceiver, CatDisplay will not cause EEPROM wear and will therefore not cause damage to the transceiver. Fail: Does not show SWR, works best if radio in VFO.===QRP whip Antenna Miracle / Miracle Ducker===*Review: [https://www.eham.net/reviews/detail/1606 The all-band rig-mounted whip] for the FT-817 (and lots of other radios too...) *Review: [https://www.eham.net/reviews/detail/5032 Miracle Ducker IL]*[https://www.universal-radio.com/catalog/hamantht/5046.html Miracle Ducker TL on Universal Radio]The Miracle Whip Antenna its cousin the Miracle Ducker are compact HF/VHF antennas for use with small portable handheld rigs like the FT817. The antenna functions via a multi-tapped toroidial inductor. An article [https://sites.google.com/site/g3xbmqrp3/antennas/mwhip here] explains, "''Its gain without a wire counterpoise was measured as 29dB below a dipole and 10dB below with one on 20m i.e. some 5 S points down using just the MW alone (i.e. poor) but only 1.5-2 S points down if a decent counterpoise or earth was used too (not at all bad).''"===MFJ-1899T HF telescoping multiband antenna 80M THRU 6M===Covers all bands 80 Meters through 6 Meters including WARC Bands.Its ten section telescoping whip is 52 inches fully extend-ed and is 7 inches when col-lapsed.*[http://www.mfjenterprises.com/Product.php?productid=MFJ-1899T MFJ-1899T] at MFJEnterprises.com
