You are very wise to acquire a 12V auto battery locally, when you arrive in Thimpu. \u00a0While Bhutan isn&#8217;t as commercially &#8220;developed&#8221; as many other countries, you can find\u00a0basics like batteries, connectors, fuses and accessories in the capital city of Thimpu.

No gazillion dollar receiver with a four mile wire strung up?<\/p>\n<p>Correct! It\u2019s a fun challenge in a great location. I want to use the radio I use now to see what I can pick up. It\u2019s a good location to pick up stations from the otherside of the world that I normally can\u2019t get, but dream about what it would be like. The PL 660 isn\u2019t a slouch when it comes to receiving, and it has SSB and the Airband! This is a fun challenge and it\u2019s a great time to enjoy listening to the shows, not just seeing what I can get. Up in the mountians, I would need to rely on my shortwave for news around the world. I mean, what day is complete without Radio Havana Cuba\u2019s slant on the news? I would hope over there I could get Iran\u2019s Voice of Justice!<\/p>\n<p>The FR-200 would be my back up to use if the solar charger breaks, or it\u2019s cloudy for awhile. It\u2019s a great portable with a built in dynamo. Plus its fun to use. Scanning the dial on an analog dial makes for relaxed listening. Kick back, pour whatever the locals drink, and see what comes in!<\/p>\n<p>As an english\/science teacher, I could introduce the students to the world and improve their english skills, while they teach me some of their language.<\/p>\n<p>Anyway, great challenge!<br \/>\nTimothy Johnson<\/p>\n<p><em><strong> I have had a lot of experience with the Grundig FR200.

It is time tested having been on the market for over a decade. In my opinion it has by far the most robust build quality in it\u2019s price range. SSB is a must, and the Sony performs well in this department, and the AM sync is a bonus feature. The main reason for my choice however, is the frugal power consumption &#8211; about 50 mA. The Sony also happily runs off a 5 V supply like a USB charger which simplifies the power issue significantly. <a title=\"eBay\" href=\"http:\/\/rover.ebay.com\/rover\/1\/711-53200-19255-0\/1?icep_ff3=9&amp;pub=5574879351&amp;toolid=10001&amp;campid=5337064312&amp;customid=&amp;icep_uq=Sony+Icf-Sw7600Gr&amp;icep_sellerId=&amp;icep_ex_kw=&amp;icep_sortBy=12&amp;icep_catId=&amp;icep_minPrice=&amp;icep_maxPrice=&amp;ipn=psmain&amp;icep_vectorid=229466&amp;kwid=902099&amp;mtid=824&amp;kw=lg\" target=\"_blank\">Price $ 130.00 on Ebay<\/a><\/p>\n<p><strong>HEADPHONES<\/strong><\/p>\n<p><a href=\"http:\/\/www.amazon.com\/gp\/product\/B003Z6AF2E\/ref=as_li_tl?ie=UTF8&amp;camp=211189&amp;creative=373489&amp;creativeASIN=B003Z6AF2E&amp;link_code=as3&amp;tag=swlcom01-20&amp;linkId=IZQL4HP2Y6I66J7Z\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-11081\" src=\"http:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/SC5GS-MainImage.jpg\" alt=\"SC5GS-MainImage\" width=\"600\" height=\"400\" srcset=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/SC5GS-MainImage.jpg 600w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/SC5GS-MainImage-300x200.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p>Headphones are a must to keep power consumption low and my choice here are the \u201cSleep Phones\u201d\u00a0<a href=\"http:\/\/www.sleepphones.com\/\" target=\"_blank\">http:\/\/www.<wbr \/>sleepphones.com\/<\/a>\u00a0The fantastic thing is that these also keep your ears warm (Himalayan winters) and of course you can use them in bed without the discomfort normal headphones or earbuds usually give. <a href=\"http:\/\/www.amazon.com\/gp\/product\/B003Z6AF2E\/ref=as_li_tl?ie=UTF8&amp;camp=211189&amp;creative=373489&amp;creativeASIN=B003Z6AF2E&amp;link_code=as3&amp;tag=swlcom01-20&amp;linkId=IZQL4HP2Y6I66J7Z\" target=\"_blank\">Price $ 40.00<\/a><\/p>\n<p><strong>TRANSCEIVER<\/strong><\/p>\n<p><a href=\"http:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/Anil-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-11082\" src=\"http:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/Anil-1-1024x683.jpg\" alt=\"Anil-1\" width=\"640\" height=\"426\" srcset=\"https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/Anil-1-1024x683.jpg 1024w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/Anil-1-300x200.jpg 300w, https:\/\/swling.com\/blog\/wp-content\/uploads\/2014\/10\/Anil-1.jpg 1498w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><\/p>\n<p>Being a ham, it is obvious that a transceiver will have to be a part of the plan.

What I like best is that your kit is based on your experience both with alternative energy and the equipment you&#8217;d plan to use. Having built a solar house myself, I also consulted a solar isolation map when\u00a0first tackling this Bhutanese challenge. You&#8217;re right: unless you have a semi-permanent PV system\u00a0to trickle charge a battery anytime you have solar gain, you could be disappointed if relying on portable solar alone. Though I had heard about <a title=\"BioLite\" href=\"http:\/\/www.amazon.com\/gp\/product\/B00BQHET9O\/ref=as_li_tl?ie=UTF8&amp;camp=211189&amp;creative=373489&amp;creativeASIN=B00BQHET9O&amp;link_code=as3&amp;tag=swlcom01-20&amp;linkId=VTF4UXJ6KPX6Y2DL\" target=\"_blank\">the BioLite<\/a>, I&#8217;ve never used one. I&#8217;m very tempted to buy one now. \u00a0I see where it could provide two important resources at once: heat and power. I also love the idea of the\u00a0<strong>Mizuho MX-14s HT transceiver; though it&#8217;s limited to 20 meters, that would be one of the best and most useful bands if you decided to get on the air. I&#8217;ve read that the\u00a0<strong>Mizuho is nearly bullet-proof. Still,<\/strong><\/strong>\u00a0like Ariel with the K2, I would consult <strong>Mizuho MX-14s users in advance of the trip and perhaps stock up on components that commonly fail. Looks like they would be relatively easy to replace in the field (with an inexpensive battery-powered soldering iron).
